risc-v indeed is getting more and more developers. I also looked into it a lot. In principle, there is a chance that some of the openwifi low level state machines (for low MAC protocol) could be replaced by some simple risc-v cores. -- Just some wild/initial ideas, no resource/action planned yet.

Even "simple" IP blocks like usb support take time. While I really like "chisel" as a design language, it is far behind what arm and intel use. But: With the mips licensees scrambling to reuse their IP, somehow, and move to risc-v, I think this architecture has an ever increasing chance of success. It's been a really good couple of months for open source this or that. I keep hoping someone will seriously fund https://github.com/open-sdr/openwifi as well, for, in order to handle the complexities of 802.11n and beyond, a co-processor with some serious oomph, and a well designed piece of open firmware, is needed. -- "For a successful technology, reality must take precedence over public relations, for Mother Nature cannot be fooled" - Richard Feynman dave@taht.net CTO, TekLibre, LLC Tel: 1-831-435-0729
