The OpenHW Foundation (formerly OpenHW Group) is an international non-profit organization that develops open source processor cores and related hardware IP artefacts based on the RISC-V instruction set architecture. Founded in 2019, the organization coordinates collaborative development of production-grade open semiconductor hardware among semiconductor companies, research institutions, and universities. Since 2025, it has operated as an Eclipse Foundation working group.

History

The OpenHW Group was founded in June 2019[1] . According to EE Times, the organization was established to address the gap between academic RISC-V research and commercially deployable processor intellectual property by producing industrial-grade open source processor cores[2].

In 2023 Florian Wohlrab succeeded founder Rick O'Connor as chief executive officer[3].

In October 2025, the OpenHW Group announced that it would join the Eclipse Foundation, where it was re-established as the OpenHW Foundation[4][5][6][7].

Organization

The foundation operates under the Eclipse Foundation's vendor-neutral governance model. Technical activities are overseen by a Technical Steering Committee composed of representatives from member organizations.

Projects

The foundation's primary technical activity is development of the CORE-V family of RISC-V processor cores together with associated verification environments and interface specifications:

  • CVA6, a 64-bit application processor derived from ETH Zürich's Ariane processor
  • CV32E40P, a 32-bit embedded processor originating from the PULP Platform
  • CV32E40S and CV32E40X, embedded processor cores targeting safety and extensibility
  • CVE2, a family of compact embedded processors derived from lowRISC's Ibex processor
  • CV-Wally, an 64bit application ready processor from Harvey Mudd Collage
  • CORE-ET, an open source edge AI fabric IP leveraging RISC-V Cores
  • CORE-V-VERIF, an open verification environment for CORE-V processors
  • CV-X-IF, an interface specification for integrating custom accelerators with RISC-V processors
  • OBI, an interface protocol used for point-to-point interfaces to instruction and data memories in embedded systems

The foundation also contributes to collaborative European semiconductor initiatives, including the Chips Joint Undertaking project TRISTAN[8] and hosts the Unified RISC-V IP Access Platform[9].

Industry adoption

The OpenHW Foundation's processor cores have been incorporated into multiple hardware and software platforms.

In 2022 the organization introduced the CORE-V MCU Development Kit, an open-source microcontroller platform intended to simplify development and evaluation of RISC-V systems[10].

In 2023 the foundation announced the CORE-V CVA6 Platform Project, intended to provide a complete software and hardware platform around the CVA6 processor[11].

In 2026, Thales demonstrated a performance model of the OpenHW Foundation CVA6 RISC-V processor to evaluate performance-related modifications before implementing them in RTL[12][13].

In 2026 the Eclipse Foundation announced that the ThreadX v6.5.1 release, made available in June 2026, added support for the CVA6 core and the CORE-V MCU. The project team stated its intent to work on CV-Wally support in the future[14].
