CORE-V Cores Roadmap

By Davide Schiavone (OpenHW Group) and Jérôme Quévremont (Thales Research & Technology).

This session will present the roadmap for the CORE-V Family of open-source RISC-V cores as maintained by the OpenHW Cores Task Group. Originally developed by the PULP Platform team at ETH Zurich under the names “RI5CY” and “Ariane”, the CORE-V Family consists of a range of embedded and application class open-source RISC-V cores for use in high-volume production SoCs.

Pasquale Davide Schiavone is the Director of Eng. of Core Task Group (design team) of the OpenHW Group. He obtained the PhD title at the Integrated Systems Laboratory of ETH Zurich in the Digital Systems group in 2020, and the BSc. and MSc. from "Politecnico di Torino" in computer engineering in 2013 and 2016, respectively. His main activities are the RISC-V CPU design and low-power energy-efficient computer architectures for smart systems and human-machine interfaces. He visited the Centre of Bio-Inspired Technology at Imperial College London in the Next Generation Neural Interfaces group from January to June 2018. Since the PhD, he delivers training workshops to companies and universities.

Jérôme Quévremont is RISC-V and open hardware project leader at Thales Research and Technology (TRT), Palaiseau, France. He serves as the OpenHW Group Cores TG vice-chair and the technical leader of the CVA6 application core project. He is also the chairman of the Functional Safety special interest group at RISC-V International.

Questions & answers by all speakers.

Any silicon chip is only as good as the software ecosystem which accompanies it. The software Task Group's mission is to drive the creation of this ecosystem for OpenHW Group processors. Not just developing key software elements needed, but also encouraging the growth of a thriving commercial community which can develop and maintain this software for the long term. In this session we'll hear about the four main pillars of our work: compilers, operating systems, IDEs and modeling. The presenters are the engineering leads for their projects. They will focus on the technology they are developing, and demonstrate the software in operation. We hope that having listened to these talks you will be inspired, not just to use the tools, but to join the collaborative teams from around the world who are developing them.

Jeremy Bennett chairs the OpenHW Group Software Task Group. He is Chief Executive of Embecosm, a consultancy developing open source compilers, operating systems, silicon chip models and AI/ML solutions based in the UK and Germany. A former academic, Dr. Bennett is author of the standard textbook “Introduction to Compiling Techniques” (McGraw-Hill 1990, 1995, 2003). He also serves as Chair of the British Computer Society Open Source Specialist Group.

Simon Davidmann is founder and CEO of Imperas and initiator of Open Virtual Platforms (www.OVPworld.org). Prior to founding Imperas, Simon was a VP in Synopsys following its successful acquisition of Co-Design Automation, the developer of SystemVerilog. Prior to founding Co-Design Automation, Simon was an executive or European GM with 5 US-based EDA startups including Chronologic Simulation, which pioneered the compiled code simulator VCS, and Ambit. Simon was one of the original developers of the HILO logic simulation system, and co-authored the definitive book on SystemVerilog.

Alexander Fedorov is ArSysOp Founder and CEO, active Open Source contributor and conference speaker. After 20 years of working in the area of IDE and tools with TogetherSoft, Borland, Micro Focus, Embarcadero, NXP and others, he switched to consulting on architecture and development for Eclipse-based solutions.

Alfredo is the father of three daughters and he lives in Ottawa with his wife Marieke.

Ivan Kravets is founder and CEO of PlatformIO Labs (https://piolabs.org). He founded PlatformIO in 2014 to solve the problem of multi-platform development in the embedded systems industry. Their unique philosophy gives embedded developers true freedom – to personally decide which operating system, integrated development environment, and hardware to use. At PlatformIO Labs, they believe the embedded systems industry desperately needs reinvention. Not only are the IDEs and tools built with technology from the 1990s, but the complex requirements for embedded engineers.

CORE-V MCU & APU

By Florian Zaruba (OpenHW Group).

In this talk, we will give an overview of the OpenHW CORE-V open-source embedded MCU and application class APU platforms. The CORE-V MCU is built around the CORE-V CV32E40P, a four-stage, in-order, embedded-class core with custom instruction set extension for DSP centric applications. Furthermore, the CORE-V MCU SoC comes with an FPGA prototyping flow for the widely used Digilent Genesys II board and a rich set of software development tools and toolchain support. Also, OpenHW will manufacture and make available our CORE-V MCU in Globalfoundries 22FDX together with an embedded FPGA from Quicklogic for custom logic such as accelerators. The CORE-V APU is built around the CORE-V CV64A6 a 6-stage, single issue, in-order CPU which implements the 64-bit RISC-V instruction set. It fully implements I, M, A and C extensions as specified in Volume I: User-Level ISA v2.3 as well as the draft privilege extension v1.10. It implements three privilege levels M, S, U to fully support a Unix-like operating system. The CORE-V APU comes with an FPGA prototyping flow for the widely used Digilent Genesys II board and a rich set of software development tools, toolchain support and bootable Linux image.
