RISC-V architecture, and a few implementations are released under BSD licence. In contrast, ARM Holdings or MIPS Technologies don't allow others to use their architectures without paying royalty fees. For example, the Chinese Academy of Sciences designed Loongson processor from the scratch, but had to pay to MIPS Technologies in order to base it on the MIPS IV instruction set. Zeljko Jovanovic

I hear it's only truly open if you're part of their exclusive "club". Otherwise it's as much "you take what you're given" as any other architecture. If you're willing to do a port, I doubt any here could stop you. RISC-V hardware needs to become available though before such a port will become any practical use. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere.

URLs and PDFs don't help the software development process. PDF isn't turing complete, so you can't write a cpu emulator in it. Press releases are not helpful. Only hardware in-hand helps.
