A Posit Arithmetic Unit Enabled RISC-V Processor - Aneesh Raveendran & Vivian Desalphine, Centre for Development of Advanced Computing, Bangalore, India
Posit arithmetic is popularly being discussed and analysed in research community about providing better accuracy and larger dynamic range than conventional IEEE 754-2008 based Floating point arithmetic. Such analysis has catalyzed the efforts in applying such new arithmetic for various applications domains viz. scientific, signal processing, AI/ML etc. This work presents a Posit Arithmetic Unit (P16, P32, P64, quire: parameterizable) enabled RISC-V processor (RV64IMAFD) architected with 6-stages in-order pipeline and FreeRTOS bootable. The RISC-V processor supports either IEEE 754-2008 FP or Posit (RISC-V F and D ISA based) arithmetic. The Posit unit has been verified with an in-house developed Posit domain specific verification suite, PositGen. RISC-V GCC software toolchain has been suitably enhanced to support Posit data representation in applications. Posit enabled RISC-V core and IEEE 754-2008 FP enabled RISC-V core have been evaluated independently with a set of computational programs and the results have been compared and analyzed for accuracy. Further, Posit and IEEE 754-2008 FPU unit has been compared and analyzed for hardware resources (area) complexity and latency.

Lightning Talk: A System Level Verification and Validation Environment using SweRV - Anupam Bakshi, Agnisys, Inc.
In a SoC development cycle, a vast amount of time is consumed verifying a given specification for its functional correctness before the actual tape-out of the design. The earlier you can recreate the final environment that the IP/SoC will operate in, the faster you will tape-out. We propose an advanced verification and validation environment involving the SweRV core from Western Digital to show how to automatically generate and run reusable tests, both standard as well as custom at different levels of IP/SoC verification and validation to ensure functional accuracy of the design along with 100% out-of-the box coverage.

Lightning Talk: How to Extend RISC-V to Accelerate AI/ML - Veronia Iskandar, TU Dresden & Dr. William Jones, Embecosm
We present the development of a simple ISA extension to the Open Hardware Group's CV32E40P core, extending earlier work from the University of Southampton (https://youtu.be/t0Fpy4TzLUE). We have created a physical realization on the Nexys-A7 FPGA board under the 2021 Google Summer of Code program. We add a subset of just 8 instructions from the V extension to the Open Hardware Group CV32E0P core. The CV32E40P features an Auxiliary Processing Unit (APU) interface. This follows a subset of the OBI interface used to communicate with system memory. We use this interface for the accelerator. Several modifications were required to the core RTL in order to better support the architecture of the accelerator, primarily in regards to multi-cycle instructions. The accelerator and core RTL are then taken through the stages of FPGA development, starting from bitstream generation to debugging binary files on the FPGA. The result is a small RV32 core which speeds up the standard TinyMLPerf benchmark more than 5-fold. An important result for those looking to accelerate low energy AI inference at the edge and a free and open reference code base for others wishing to build on this work.

Open Hardware for the Open Cloud - Daniel Mangum, Upbound
While RISC-V is revolutionizing the world of Instruction Set Architectures by taking an open, community-based approach to development of the ISA itself, reference implementations, and the software ecosystem that surrounds it, a parallel movement is also taking place in the world of cloud computing. Similar to ISAs other than RISC-V, cloud platforms have traditionally exposed an interface for users to interact with, typically via a REST API, but the implementation details have remained proprietary. Additionally, the heterogeneous nature of cloud provider APIs has led to a disparate ecosystem of software used to interact with the platforms. In this talk we'll examine how the cloud ecosystem is experiencing a revolution similar to the open hardware movement, then explore what a future looks like when these two efforts coalesce.

Lightning Talk: Open-Source RISC-V Cores with Industrial Strength Verification - Simon Davidmann & Lee Moore, Imperas Software
This case study explores the background, development and implementation of the OpenHW verification environment for CV32E40P known as “core-v-verif”. Since the goal of the project is to support adoption on of an open-source IP core, the initial deliverable quality is not the only concern. One attractive aspect of an open-source core is the potential for adopters to modify, adapt, or extend the base core features. Thus, the verification plan needs to anticipate the future use case with flexibility built in to the testbench to accommodate future modifications as adopters extend the core features.

Lightning Talk: De-RISC, the Horizon 2020 Project that will Create the First RISC-V, Fully European Platform for Aerospace - Paco Gómez-Molinero, fentISS
The world market for aerospace computing systems faces a significant shift caused by the loss of momentum of the traditionally used instruction set architectures in the commercial domain. RISC-V offers a unique opportunity to develop EU-based products for the aerospace domain with no dependence on non-European technology or proprietary IP rights, which would impose licensing fees and export restrictions otherwise. De-RISC project brings together leading European entities within the areas of fault-tolerant microprocessors, hypervisors, embedded safety-critical software and mixed-criticality systems in an effort to commercialize a complete technology stack. The goal is to create a multicore platform for the aerospace industry based on the open RISC-V instruction set architecture together with specific features to address the needs of the target industries and to adopt modern commercial technology leveraging technology developments for other domains. This session covers concepts related to hardware Systems-on-Chip, XtratuM hypervisor, space qualification, and use cases for RISC-V based systems supporting high integrity levels, mixed-criticality, high performance, and dependability.

Lightning Talk: Adding 32-bit Linux Support to ARIANE/CVA6 Open-source Application Core - Sébastien Jacq & Jérôme Quévremont, Thales
Together with OpenHW, Thales runs the CVA6 project, to transform ETH Zürich and University of Bologna’s ARIANE famous RISC-V application core into an industrial-grade core available as open-source for the community. From the original 64-bit ARIANE SystemVerilog design, renamed CV64A6 by OpenHW, Thales has created a 32-bit flavor, CV32A6, a resource-optimized version for embedded applications that need to support rich OSes like Linux. CV64A6 and CV32A6 share the same code base “CVA6”. In this talk, members of the CVA6 team will present the journey towards the support of Linux by CV32A6: designing a new 32-bit (Sv32) MMU, debugging the 32-bit pipeline, integrating a bootloader and Linux kernel with Buildroot, running a HW/SW integration and debugging and finally demonstrating a running Linux on a FPGA board. As a takeaway, the audience will be pointed to the open-source repositories that they can use to implement CVA6 and Linux when they return home. The next steps in this open-source project are the optimization of CV32A6 to target FPGA platforms (in addition to ASIC technologies), the addition of a few safe&secure features, more verification to get an industrial-grade IP…

Vitruvius: An Area-Efficient RISC-V Decoupled Vector Accelerator for High Performance Computing - Francesco Minervini & Oscar Palomar Perez, Barcelona Supercomputing Center - BSC
The availability of domain-specific instruction set extensions, like vector processing, make RISC-V a good candidate for supporting the integration of specialized hardware in processor cores. This talk presents Vitruvius, the first RISC-V vector accelerator developed at BSC for the Supercomputing domain. Vitruvius is compliant with the RISC-V vector extension specification V0.7.1. and can be easily connected to a scalar core using the Open Vector Interface (OVI) standard in a plug-and-play fashion. Vitruvius natively supports long vectors: 256 Double Precision (DP) floating-point elements in a single vector instruction. It is composed of a set of identical vector pipelines (lanes), each containing a slice of the Vector Register File (VRF) and functional units (one integer, one floating-point). It adopts a novel hybrid in-order/out-of-order execution scheme, supported by vector register renaming and arithmetic/memory instruction decoupling. When configured with eight vector lanes, Vitruvius reaches a maximum frequency of 1.25 GHz when synthesized using GLOBALFOUNDRIES 22FDX FD-SOI. The silicon implementation has a total area of 1.13 mm2 and total estimated power of 1648 mW.

Keynote: Are the RISC-V Design Freedoms Leading to RISK in Verification Quality? - Larry Lapides, Vice President Sales, Imperas Software Ltd.
Traditional SoC projects estimate that 50-80% of the cost/effort will be for verification, but that is based the traditional approach using mainstream providers with pre-verified processor IP cores. RISC-V offers more options to SoC Developers, from developing a custom core, downloading an open-source project, selecting from one of the new IP providers, plus adding custom instructions to any of these starting points.
The flexibility of RISC-V appears to imply an increase in the DV scope of work for any SoC project with a customized RISC-V core, in this talk we will introduce the Imperas Reference Model based solutions for RISC-V processor verification.

The Open Hardware Diversity Alliance formed in September 2021 with a partnership between RISC-V, Chips Alliance, OpenPower Foundation, and Western Digital with a mission to provide programs to encourage participation and support the professional advancement of women and underrepresented individuals in open source hardware.

We asked ourselves: 
  • Why are there few women and underrepresented individuals in the open hardware community?
  • Is it because open hardware is hard to navigate? 
  • Is career progression a mystery? 
  • Is it a lack of visibility of the talent in open hardware to the community?
Kim and Marjan will talk about the goals of the Alliance, upcoming programs, and how you can get involved.  Sujata will join to share their experiences on how they got involved in technology and the path to success as a Technology Evangelist at Intel and a leader in the open source technology industry.

RISC-V on Edge: Porting EVE and Alpine Linux to RISC-V - Roman Shaposhnik & Kathy Giori, ZEDEDA Inc.
What is special about community-industry collaboration around an open architecture like RISC-V is that the community can join development around key kernel subsystems in parallel with the semiconductor companies and manufacturers as they are producing the new chipsets and boards. Open silicon design, open board design, and open kernel software speeds bring-up of new boards and fosters greater innovation due to the diversity of talent contributing to the technology. For many kernel developers, tackling RISC-V is becoming harder to resist now that commercially viable and scalable hardware has begun to enter the market. A private beta program launched by the BeagleBoard Foundation in March 2021 placed an affordable, yet powerful prototype RISC-V board into the hands of Roman Shaposhnik. What did Roman do? He joined a diverse team of software and hardware hackers to tackle bringing up Linux on the new board. In this talk, Roman will tell you about his experience porting Alpine Linux and LF Edge EVE-OS to the new RISC-V architecture.

Lightning Talk: Accelerating Real-World AI Software using the RISC-V Vector Extension - Colin Davidson & Alastair Murray, Codeplay Software
Software developers and processor designers are looking to accelerate the latest AI and machine learning applications requiring parallel processing architectures. The RISC-V Vector (RVV) extension is a recent addition to the RISC-V ISA providing the basis for translating vector and scalar based computation onto parallel processor cores. RVV defines a way to accelerate AI computation, e.g., tensor datasets, in parallel on multi-core processors. However, the extension only defines the interface, and still needs to be implemented at the compiler level to enable the division of workload across different processors. This presentation will show how Codeplay has enabled neural network software algorithms to execute on the RVV extension with automatic vectorization; all using open standards including SYCL, and open-source software. We will explore the practical steps needed to implement RVV using a Spike simulator, the required software frameworks, libraries, and toolkits to bring together, and how to enable a complex application using a real-world neural network.

Algorithm Acceleration for RISC-V Processors using High-Level Synthesis - Russell Klein, Siemens EDA
Increasing the performance and efficiency of a RISC-V designs can be done by moving compute intensive functions from software, running on the CPU, into hardware accelerators. These accelerators can take the form of new instructions, co-processors, or bus based peripherals. One way to create this type of accelerator is to use High-Level Synthesis (HLS). HLS takes a C or C++ function and synthesizes a functionally equivalent Register Transfer Level (RTL) hardware description. This RTL description can be used to create the hardware accelerator for an ASIC or FPGA. This session will show you how to create different types of accelerators using HLS and how to integrate them into RISC-V processor designs. An AI inferencing algorithm and a an encryption algorithm will be used as examples to show how the accelerator can impact the performance and power consumption of a RISC-V design.

Lightning Talk: Using and Extending RISC-V in an Analog Matrix Processor for Neural Networks - David Luo, Mythic & Dr Zdeněk Přikryl, Codasip
A characteristic of the RISC-V ISA is its provision for custom extensions enabling the ISA to be tailored to the needs of a particular workload. Mythic has developed the M1076 Analog Matrix Processor (AMP) chip for implementing neural networks for applications such as intelligent camera systems, robotics, etc. The AMP includes a configurable array of tiles. Each tile consists of a large analog compute engine, which stores the neural network weights, a local SRAM memory for data being passed between the neural network nodes, an SIMD unit for processing operations not handled by the analog compute array, and a RISC-V processor for controlling the sequencing and operation of the tile. The RISC-V processor is described in an architectural language which means that it is possible to extend the core by describing additional instructions and automatically generating the SDK, RTL and verification environment. This paper describes the AMP architecture and the requirements for extending the RISC-V processor to meet the sequencing and control needs. The paper describes how custom instructions were chosen and implemented in the architecture description language rather than RTL

Advanced Interrupt Architecture and Advanced CLINT - Anup Patel, Western Digital & John Hauser, Independent Researcher
The existing RISC-V platforms only support wired interrupts, machine-level timer interrupts and machine-level software interrupts in hardware hence there is no hardware support for message signaled interrupts (MSIs), MSI virtualization, and supervisor-level software interrupts. The advanced interrupt architecture (AIA) specification defines new interrupt controllers to support wired interrupts, MSIs and MSI virtualization in manner scalable for large number of HARTs. The advanced core local interruptor (ACLINT) specification defines separate devices for machine-level timer interrupts, machine-level software interrupts, and supervisor-level software interrupts in a manner backward-compatible for existing RISC-V platforms. The AIA and ACLINT specifications collectively address interrupt and timer requirements of different classes of RISC-V platforms.

Support for Non-Coherent I/O Devices in RISC-V - Greg Favor & David Kruckemyer, Ventana Micro Systems
The current RISC-V ISA privilege specification only defines a broad physical memory attribute (PMA) mechanism to implement non-cacheable memory regions for any non-coherent I/O devices. While this is an acceptable approach in an embedded world, it is not sufficient for modern-day systems where the number of programmable PMAs will not scale. On other hand, having a fully coherent system is not always feasible due to design costs in spite of performance advantages. Thus, any platform with non- coherent I/O devices relies on the software managed coherency, a widely adopted approach in today's industry. The software can manage coherency either by accessing the memory in such a way that it is never cached or use cache maintenance instructions for cacheable memory. The Svpbmt(Page Based Memory Type) extension was recently proposed to provide a solution to the first approach while a set of CMO(Zicbom, Zicboz, and Zicbop) extensions are the solution to the second approach. These proposed extensions allow the platform vendors to build cost-effective RISC-V systems that are truly on par with other ISAs. This talk will outline the technical details and current status of both extensions.

Performance Monitoring in RISC-V using perf - Atish Patra, Western Digital
Performance analysis using a dedicated hardware performance monitoring unit(PMU) has become ubiquitous in the modern era of computing. A PMU unit consists of several programmable registers that can be used to monitor micro-architectural information using userspace tools such as perf. This was one of the key missing pieces in RISC-V software ecosystem until now. Linux kernel for RISC-V had a very basic perf support due to the missing features in RISC-V ISA. However, an SBI PMU extension and ISA extension ("SScofpmf") were recently proposed. This allows developing a RISC-V platform that is on par with any other ISA in terms of perf capabilities including virtualization support. The SBI PMU extension also added support for a set of novel firmware counters to allow users to gain insight into firmware data during performance analysis. Linux kernel and firmware support for both the proposed extension are under development. This talk will provide the details of these extensions. It will also describe the Linux perf subsystem architecture and Linux RISC-V perf driver that leverages these extensions. In the end, a live demonstration of the full capabilities of perf will be shown using Qemu.

Demo: Formal Verification of RISC-V Cores - Saša Stamenković, OneSpin
Pre-silicon verification of processors is a challenging, time-consuming task. IP providers offering proprietary ISA cores leverage decades of effort and state-of-the-art EDA tools. RISC-V cores for commercial applications must achieve the same level of quality while facing the additional challenge of their own custom instructions of registers.

This demo session presents a fully-fledged environment for the formal verification signoff of RISC-V cores. Its main inputs are the target RTL core and a description of the custom extensions. It produces a set of assertions capturing that the RTL faithfully implements the chosen ISA with its custom extensions and nothing else. These assertions are exhaustively proven on the RTL.

Efficient Issue Scheduling for Hardware Multithreaded RISC-V Pipeline - Dr. Shlomo Greenberg, Ben Gurion University of the Negev & Sami Shamoon College Engineering, Beer-Sheva, Israel
Hardware multithreading is a common approach for tolerating memory latency by utilizing idle cycles and avoid- ing CPU stalling. Nowadays, multithreading architectures are commonly used across many processors and various embedded edge devices to improve performance. This work suggests a new multithreading in-order pipeline microarchitecture design for RISC-V and proposes an efficient event-based issue scheduling algorithm. The proposed scheduling algorithm is based on the unique RISC-V ISA that enables decoding of the instruction type in an early stage of the pipeline. The RISC-V-based mul- tithreading architecture is evaluated using a dedicated software simulator. Simulation results show that the proposed algorithm outperforms the classical Round Robin and the coarse grain algorithms. The proposed architecture is evaluated using the standard MiBench benchmark and other common applications, demonstrating pipeline utilization improvement of up to about 26% in terms of IPC using four threads.

Empowering electronic devices to support Post-Quantum Cryptography (PQC) is a challenging task. Especially for low cost and resource constraint devices, hardware acceleration is usually required. The speaker presents RISQV-HT, an enhanced RISC-V device that integrates a set of powerful tightly coupled accelerators to speed up lattice and isogeny-based PQC. The RISC-V ISA is extended with 41 new instructions and performs roughly 10 times faster than a software solution when encrypting with Kyber and 21 times faster when encrypting with SIKE.

As a twist, four hardware Trojans were inserted into the final chip, threatening the security properties of integrity, confidentiality and availability. The speaker shows how to detect such Trojans with tape-out-tools and reverse engineering.

The RISQV-HT was implemented in ASIC technology and taped-out at the end of 2020.

The Future of RISC-V Heterogeneous Embedded Virtualization Architectures - Sandro Pinto & José Martins, Universidade do Minho
Today’s embedded industries exhibit a strong trend towards consolidation. Virtualization is the de facto technology used to achieve this goal, since (i) it provides strong isolation between partitions and (ii) eases the porting and integration engineering costs. However, a single hypervisor might not be suited for the heterogeneous requirements of different partitions. This results in the selection of feature-rich hypervisors with large TCBs, typically consisting of the system’s single point of failure. In this talk, we share our experience while implementing the latest RISC-V (i) Hypervisor and (ii) enhanced PMP (Smepmp) extensions on the RISC-V CVA6 core, and we explain how these extensions can be synergically leveraged to implement a novel heterogeneous partitioning and virtualization architecture with enhanced security and safety guarantees. In this architecture, a hardened implementation of OpenSBI domains is used to partition system resources (i.e., memory, peripherals, interrupts), enabling the deployment of distinct hypervisors per partition, according to its requirements. We end with an illustration of possible use cases and a discussion on how to orchestrate such systems.

Lightning Talk: Enabling Software Emulation for RISC-V Heterogeneous Cores Architecture - Cui Jin & Ley Foon Tan, StarFive Technology
RISC-V has a lot of optional extensions following different version specifications. When integrating these heterogenous cores in a hybrid architecture SoC, usually it brings a lot of issues for software stacks. For instance, the big core and little core have different version of F extension, or the big core supports V extension while the small core does not.  In such scenario, software stack developers have more concern to support such heterogenous architecture and enable the development and verification far ahead of hardware available. In this proposal, QEMU is modified for such purpose to assist developer to build this hybrid architecture with desired configurations and run software stack on it. With the modifications, a Linux running in AMP way is also shown as an example on this emulation platform. With Linux kernel has per-core capabilities/extensions to be identified (in this proposal, the V and non-V extension is tested), the AMP (relative to SMP) is successfully running with vector and non-vector applications mixed under the normal kernel scheduling.

AI-RISC - Custom Extensions to RISC-V for Energy-efficient AI Inference at the Edge of IoT - Vaibhav Verma, University of Virginia
Numerous hardware accelerators have been proposed to meet the performance and energy-efficiency requirements of AI applications. But these accelerators have been developed in separate silos with little to no infrastructure for integrating these accelerators in the top-level system stack. We present AI-RISC as a solution to bridge this research gap. AI-RISC is a hardware/software codesign methodology where AI accelerators are integrated in the RISC-V processor pipeline at a fine-granularity and treated as regular functional units during the execution of instructions. AI-RISC also extends the RISC-V ISA with custom instructions which directly target these AI functional units (AFU) resulting in a tight integration of AI accelerators with the processor. AI-RISC adopts a 2-step compilation strategy where open-source TVM is used as the front-end compiler while LLVM based custom C-compiler is used as the backend along with complete SDK generation. AI-RISC enables a RISC-V based processor which supports both AI and non-AI workloads for edge applications, flexibly hot-swaps AFUs when better hardware is available and scales with new instructions as AI algorithms evolve in the future.

Sail Specification for RISC-V P-Extension - Bow-Yaw Wang, Academia Sinica, Taiwan & Jenq-Kuen Lee, National Tsing Hua University, Taiwan
RISC-V P-extension (RVP) is designed for digital signal processing (DSP) applications on RISC-V instruction set architecture. RVP supports parallel processing with 325 new instructions. Among them, 173 Single-Instruction-Multiple-Data (SIMD) instructions are added. These instructions divide general purposed registers into 8-, 16-, 32-, or 64-bit chunks and compute an arithmetic function in parallel. RVP also contains special instructions for DSP such as cross multiplication and saturated computation. The RVP specification is a text document maintained by the RVP work group. We present a Sail specification for RVP in this work. To reduce manual and maintenance efforts, tedious Sail specifications for binary encoder/decoder and assembly mnemonics are generated automatically. We explain how dependent-type programming in Sail simplifies our semantic functions for RVP. Writing semantic functions for 325 instructions in RVP is still tedious and prone to errors. Inconsistency between the textual RVP specification and our Sail specification can be embarrassing. Using Spike, we present a workflow to validate our Sail specification for the 325 instructions defined in RVP.

(*) What do these kernel patches do for communication networks? (*) Why the performance improves compared to historical copy function (*) The way to optimize software from the book, Computer Architecture: A Quantitative Approach on RISC-V (*) Why the CPU design impacts implementation of software The patches to improve the performance of RISC-V were accepted on June 4th at the Linux Kernel Mailing List. The changes were achieved by optimizing copy functions inside the kernel by mainly reducing the misaligned memory access and pipeline stalls. The knowledge and understanding of the internals of the RISC-V is essential for optimizing hardware level software. The discussion of the optimization took place in the mailing list and forum of RISC-V development board. The RISC-V is the perfect combination of open architecture and open collaboration to improve the industry since it is open ISA and anybody could participate in the public discussions.

Lightning Talk: Functional Gap between RISC-V V and SPIR-V: a Study Case on the Graphics Domain - Abel Bernabeu, Esperanto Technologies
The RISC-V V extension opens new possibilities for RISC-V based designs, with big expectations created in the machine learning, heterogeneous computing and graphics communities. In this talk we try to answer the question of what is the functional gap between RISC-V V and the popular SPIR-V standard when handling common graphics use cases. We define the functional gap as the set of SPIR-V instructions that require an unreasonable number of instructions to implement on RISC-V V, but would take just one or two instructions on an ISA specifically designed for graphics. A thorough review of the functional gap is made for a representative study case: using SPIR-V as intermediate representation when translating GLSL shaders from the widely adopted OpenGL ES 2.0 standard to RISC-V V code. The identified functional gap is summarized here for helping the graphics community (represented on the RISC-V Graphics SIG) to familiarize themselves with the areas where work is required.

Lightning Talk: A Zero Trust Security Architecture For RISC-V SoC/ Platform - Suresh Sugumar, Technology Innovation Institute
Zero Trust (Trust no one, but always verify) has recently become a hot topic in the network security world, where it shifts the paradigm from trust-based on physical connectivity to the one that involves always authenticating every access. The US has also issued an executive order on cybersecurity to embrace Zero Trust not just for networking but also for any products/ services that we build, and semiconductors are at the heart of everything nowadays. In this talk, we shall cover a holistic view of Zero Trust right from the silicon up to software-level security, and how can improve the trust of the platform and every component in it. A platform-level Trusted Execution Environment (TEE) design with configurable and dynamic Trusted Computing Base (TCB) will be explored. A platform-level Root-of-Trust (RoT) to facilitate authentication, encryption of data exchanged between every component, and platform-wide remote attestation to verify the firmware integrity of every component in the platform will be discussed. Also, topics related to supply chain security and trusted foundry will be discussed.

Quantitative Methods for Continuously Improving RISC-V Compilers - Philipp Tomsich, VRULL
Up until now, most commercial implementations of RISC-V have focused on embedded use cases; with the emergence of RISC-V as an alternative to the ARM and Intel ecosystems, higher-end applications that include storage and the datacenter are moving into focus. This also shifts the perspective on target workloads and representative benchmarks. We show how quantitative methods can be used to assess the quality of code generation and identify and prioritize potential improvements based on hot-block analysis, dynamic instruction count metrics, and instruction histograms. The difference applicability to small benchmarks (such as Coremark, where this method identifies both a superoptimisation opportunity for the CRC functions and highlights the absence of conditional-move instructions in the RISC-V instructions set) and large benchmarks (such as SPEC, which helps to improve and mature the tools across the board) are demonstrated. The proposed methodology can provide much-needed quantitative data to the standardization of new extensions, guide future micro-architecture development and provide quality-metrics for toolchain development.

Advanced computing platforms for autonomous drone navigation are extremely challenging drivers of Internet-of-Things edge intelligence capabilities due to the mix of requirements in terms of security, safety and high performance. We present a fully RISC-V-based SoC for high-performance and secure autonomous drone navigation. The SoC includes a dual-core CVA6 core with full support for Linux OS managing the main system functions and an RTOS such as Nuttx for time-critical tasks. The SoC is supported by a complete set of peripherals, and a parallel accelerator based on the open-source PULP platform and a root-of-trust subsystem based on the open titan project. As a capability demonstrator, we present a human pose estimation task based on a novel CNN. Inference runs in real-time, up to 135 frame/s, consuming less than 87 mW on a COTS PULP-based SoC aboard a 27-grams nano-UAV, where it achieves 1 GOPS with an efficiency of more than 12 GOPS/W. The in-field deployment of our visual NN demonstrates a closed-loop top-notch autonomous navigation capability. Our novel RISC-V-based SoC is expected to push this cutting-edge end-to performance even further, as much as 2.6 GOPS and 92 GOPS/W.

Profiles and Platforms - Philipp Tomsich, VRULL & Mark Himelstein, RISC-V International
We are always asked how we will stop fragmentation amongst RISC-V. members. The incentive to not fragment is to reduce duplicated effort and share work in the software ecosystem. The "how" is answered by Profiles and Platforms. New to 2021 these standards provide a single group of extensions and OS components that enable us to tell developers and distros alike what to target for upstream projects from boot code to hypervisors, operating systems, applications and tool chains. Come learn about these standards and how they unify the RISC-V community.

A Requirements-based Test Suite for the C Standard Library: SuperGuard - Marcel Beemster, Solid Sands B.V.

Solid Sands has developed a requirement-based test suite for the C standard library, with traceability from individual test results to the requirements derived from the ISO C language specification. It is called SuperGuard and can be used to qualify C library implementations for safety-critical applications.

The ISO C specification is not a list of requirements. From it we distilled the requirements on the C library. This was a huge effort, but required for library qualification. Next we created test specifications and matched them with our existing test suite. Finally, tools were created to drive the test suite and report the test results so that they are fully traceable to the requirements and the specification.

The C library is not insensitive to the application's compilation options: many functions are implemented as macros defined in header files. Functional Safety standards clearly specify that qualification must be done for the application developer’s use-case, so this is what we make possible with SuperGuard.

In this presentation we will show the principles and practice of C standard library qualification.

Keynote: Scaling is Failing - Dr. Ron Black, CEO, Codasip
After 50 years of driving semiconductor economics, the underlying “semiconductor laws” are failing at a time when advanced manufacturing is becoming prohibitively expensive. Photonics and alternate materials such as carbon nanotubes have been suggested as alternatives but the only short-term option is to match hardware to computational workload through heterogeneous computing. RISC-V’s modularity combined with design automation provides a foundation for creating novel processors and domain-specific accelerators. Industry must adapt or die!

Demo: Processor Trace: Efficient Solutions for Today’s SoCs - Hanan Moller, Siemens EDA
RISC-V is being used in complex real-time heterogeneous systems. The software executing on such systems needs to be tuned to provide the best performance possible. Developers need insight into the operation of the software and its interaction with the underlying hardware structures, including NoCs and CPUs. A key element of this is processor trace, which allows development teams to analyze program execution, how many cycles code takes to execute, whether there are stalls and dependencies and how long they last. System designers can use these insights to make optimizations and achieve efficiency gains.

The Efficient Trace for RISC-V (E-Trace) specification supports these needs.
This presentation will outline the latest developments in E-Trace, and provide details of the features of the Embedded Analytics RISC-V Trace encoder, which implements features such as cycle-accurate and data trace, filtering, matching and SoC-wide cross-triggering, that can be used to produce significant improvements in overall system performance.

Systematically Securing the RISCV - Secure Foundation for Embedded Functionality - Marko Mitic, NVIDIA
Drawing inspiration from the academic/industry work around Multiple Independent Levels of Security and Safety (MILS), NVRISCV/Peregrine security architecture is presented that offers multiple isolated execution environments - partitions, all running on the same physical processor with SW defined and HW enforced capabilities. NVRISCV is NVIDIA’s implementation of the RISC-V ISA and Peregrine subsystem includes NVRISCV and multiple peripherals. They show how fine-grain access controls, formally verified for correctness, allow following the principle of least privilege for each partition. NVRISCV provides secure boot that starts with an immutable HW, the chain of trust extends to the Secure Monitor in SW, where partition policies are set up and isolation enforced using HW controls. Boot and Secure Monitor software is implemented in SPARK, formally verifiable programming language with verification toolset. Holistic approach on HW/SW security must consider attacks outside of defined architecture. The HW is hardened against in-field attacks, via multiple countermeasures they present in detail as well as the offensive research analysis against the architecture.

TEEP (Trusted Execution Environment Provisioning) and Software Updates for Internet of Things (SUIT) on RISC-V - Akira Tsukamoto, AIST
The presentation is about the security technology to expand the are of RISC-V on the devices that require security sensitive software and data, IoT/Edge/Network/Automotive equiments. IETF is engineering and standardizing the TEEP (Trusted Execution Environment Provisioning) protocol and (SUIT) Software Updates for Internet of Things. The TEEP is to remotely install/update a TC (Trusted Component, which was previously called Trusted Application) and SUIT manifest is a format to bundle of metadata about code/data of the TC. The implementation started only on Arm and Intel, thus we have developed TEEP and SUIT on RISC-V. TEEP handshakes between TAM(Trusted Application Manager) and the Devices while installing and updating the TC with code signing and certificates based PKI key technology. The TC would be firmware, applications and/or personal data of the Devices to installation or updates. The formats of TEEP and SUIT are encoded and decoded with CBOR (Concise Binary Object Representation) which has the benefit for small binary size to suit on resource constrained embedded devices. The presentation will also include instruction of basic concepts and design of TEEP and SUIT.

IOPMP Updates: The Protection of IOPMP - Paul Shan-Chyun Ku, Andes Technology
Platform security is an investable issue nowadays. One fundamental requirement is memory isolation. Inside a RISC-V core, PMP creates isolated spaces. In a platform, IOPMPs do it for the other bus masters. However, the system becomes vulnerable if the malicious code manipulates an IOPMP and allows illegal access. Thus, IOPMPs should also be protected. Unlike PMP, IOPMP has no corresponding CSRs whose access right is constraint by processor modes. IOPMP should recognize the legal control operations first, that is, those accesses from the security monitor. Furthermore, IOPMPs should be able to protect some sensitive data even when the security monitor is breached. A dedicated IOPMP can be used to bridge the MMIO bus and all bus masters, and at the same time to block out illegal control operations to the rest of IOPMPs as well as itself as a way of protection. Such a way controls the operations in a grain of as fine as 4 bytes. When we only want to lock several bits in a control register, e.g., enforce a certain source id to associate with a specific memory domain, we need a fine-grained lock mechanism. In this talk, we will also present these approaches to protect IOPMPs.

Architecture Design for Security: Do’s and Don’ts - Gregory T. Sullivan, Dover Microsystems, Inc.
Having ported Dover Microsystems’ CoreGuard security product to several architectures, including RISC-V, we have some lessons learned about how well-intentioned features can make the task of implementing reliable, fine-grained security gratuitously difficult. While some of our talk will focus on subtle instruction set design tradeoffs, we also have a larger, more urgent message to convey to the RISC-V community about designing an architecture that is friendly to future, innovative security products. A non-exhaustive list of gotchas from RISC-V and other ISAs: (1) exception delegation, where was EPC stored? (2) multi-word load/stores operations paused or canceled due to interrupt or exception - what loads/stores were executed; also when are we resuming? (3) lazy register spills - too clever by half! (4) punning JAL for exception return - saves max 2 instructions, adds complexity. (4) register windows and wraparound - complexity better handled in compiler than HW. We strongly encourage a general, trace-based introspection feature to support a wide range of debugging and security products, rather than per-feature-ISA extensions that will eventually throttle the ISA due to complexity.

Storage Area Network Acceleration using RDMA / RoCE and RISC-V - Pu Wang, DatenLord
In this talk, we will introduce an SoC for storage area network (SAN) acceleration. As for SAN, RDMA over Converged Ethernet (RoCE) is the mainstream solution, since its performance is close to InfiniBand and avoids special InfiniBand equipment by reusing existing Ethernet. However, the most weakness of RoCE is the flow control. RoCE depends on the flow control to prevent the underlying Ethernet from packet loss. Whereas Ethernet itself is not lossless in nature. There have been many flow control algorithms proposed for RoCE, such as HPCC, DCQCN, TIMELY, etc. But all require complex and manual parameter tuning. We build an SAN acceleration SoC by combining RoCE and RISC-V, that the RoCE protocol is implemented in hardware and the RoCE flow control algorithms are implemented as software to run in RISC-V. By doing so, we achieve both hardware acceleration for RoCE and flexibility for flow control parameter tuning, which exactly follows hardware and software co-design philosophy. Further, we leverage AI techniques to automatically tune the flow control parameters, which greatly reduces the burden of manual tuning and achieves significently better performance than the manual way.
