CORE-V Cores & RISC-V Profiles

Nov 12, 2021

As RISC-V evolves over time, the set of ISA features supported by each software ecosystem will also need to evolve over time, and new software ecosystems will be added. To manage this evolution, RISC-V is moving towards a model of regular annual delivery of a coherent set of ISA updates according to an ISA roadmap, and architecture profiles are intended to provide the natural structure for planning, packaging, and releasing these ISA updates.

In this OpenHW TV episode the general structure of RISC-V architecture profiles will be discussed. With reference to the OpenHW CORE-V cores roadmap. Speakers will explain how the CORE-V cores map to the RISC-V profiles along with a focus on the Zce upcoming RISC-V extension, that will be implemented in CV32E41P as a proof of concept project within the OpenHW ecosystem.

The session speakers include: Mark Himelstein, RISC-V International; Jerome Quevremont, Thales Group ; Tariq Kurd, Huawei and the session will be moderated by Davide Schiavone, OpenHW Group.

New CORE-V CV32E4 Family Projects

Oct 7, 2021

The CV32E4 family of open-source RISC-V CPUs is a set of processors that target embedded-class devices from edge-computing platforms to microcontrollers. This OpenHW Group TV episode shows the current state of projects surrounding the family of CORE-V IPs as: the CV32E40X for extending the computation capability of edge-nodes easily; the CV32E40S for secure applications; the CV32E20 for area-efficient microcontrollers; the CV32E40Pv2 project for completing the design and verification of the CV32E40P core for edge-computing platforms; and the CV32E41P for proving the newest Zfinx and Zce RISC-V ISA draft-extensions.

In particular, we will hear from Pascal Gouedo from the Dolphin Design team to discuss how the CV32E40Pv2 project is implemented and what are the strategies to complete it. Along with Tariq Kurd from Huawei who will describe why building the CV32E41P is important to rectify the Zfinx and Zce extensions.

The session speakers include: Pascal Gouedo, Dolphin Design; Tariq Kurd, Huawei; Davide Schiavone, OpenHW Group, and the session will be moderated by Rick O’Connor, OpenHW Group.

CORE-V eXtension I/F

Jun 24, 2021

A key feature of the free and open RISC-V ISA is extensibility with the ability to add user-defined custom accelerators and instructions. The CORE-V eXtension I/F project within the OpenHW Group aims to provide a standard reusable interface to simplify how these custom accelerators can be connected to the family of CORE-V cores.

The webinar provides an overview of the CORE-V eXtension I/F, the project structure and roadmap as well as the SW tool chain implications of custom instructions. We’ll also hear from one of the newest OpenHW Group members, Imagination Technologies and their motivations for joining the OpenHW ecosystem.

The session speakers include: Tim Whitfield and Trefor Southwell, Imagination Technologies; Jeremy Bennett, Embecosm; Davide Schiavone, OpenHW and the session will be moderated by Rick O’Connor, OpenHW.

OpenHW CI / CD Environment

May 27, 2021

This OpenHW TV episode highlights the motivation behind the OpenHW continuous integration (CI) environment and the benefits it delivers to open source development.

The episode (broadcast live on May 27) dives into the importance of continuous integration, takes a closer look at the OpenHW CI environment, and examines how CI is employed specifically within the CORE-V Verification Test Bench and the CORE-V MCU projects.

Additionally, the webinar explores the OpenHW core-v-verif GitHub repository, the distributed workflow in place, as well as the branching strategy used to manage multiple CORE-V core verification projects within a single repository.

The expert panel includes Tim Saxe (QuickLogic) and Aimee Sutton (Metrics) alongside Mike Thompson and Florian Zaruba (OpenHW Group).

There is a 30 minute Q&A session moderated by Rick O’Connor, OpenHW Group President and CEO after around 30 minutes of presentations.
