OpenSPARC is under the GPL, which is probably why it didn't go anywhere directly. OpenPOWER is under permissive creative commons licenses, and people are iterating on the open source cores released by them. But the arrangement with efabless didn't go anywhere, and the company shut down last year without warning. So there's nowhere to experiment with producing chips.
- initramfs 2mo agohttps://wafer.space https://wafer.space allows chips but I think tinytapeout became what efabless was doing: https://chipfoundry.io/ https://chipfoundry.io/ Also Hitachi's SH-2 & SH-4 patents expired in 2016, so J-core picked up where they left off: https://j-core.org/ https://j-core.org/ MIPS also went open source around 2018: https://www.datacenterknowledge.com/data-center-hardware/mips-joins-risc-v-as-second-open-source-alternative-to-arm https://www.datacenterknowledge.com/data-center-hardware/mip...
- Conan_Kudo 1mo agoThe "MIPS Open" program never launched. MIPS itself eventually pivoted to RISC-V, and is now owned by Globalfoundries. I don't think the j-core effort is still active? It would be interesting to see it continue, though.
