Presumably similarly troublesome to licensing SiFive's proprietary IP?
- dkjaudyeqooe 4y agoThe RISC-V arch (instruction set) is not proprietary and freely available. SiFive doesn't licence instruction sets, only implementations thereof. ARM architecture licences are used when you want to do a largely complete re-implementation of the arch, so the instruction set is really the only issue.
- brucehoult 4y agoNo one has to license anything from SiFive if they don't want to. SiFive don't own any rights to the RISC-V instruction set, only to the cores they design themselves. Anyone who wants to can design and sell their own RISC-V implementation (as Nuvia and Qualcomm paid ARM [1] to do with the ARM ISA) without asking anyone for permission, without telling anyone if they don't want to, and without paying anything to anyone. [1] just, apparently, not enough
