RISC-V Exchange: Cores & SoCs - RISC-V International

This page is a collection of available intellectual property (IP) cores and SoCs in the RISC-V ecosystem. This list is curated by the community – which includes you! Add cores, SoC platforms, and SoCs to the list by filing a pull request on the GitHub repository. If you have any questions about this process, contact us for help.

Please note that the Exchange can showcase available physical hardware on the Available Boards page.
