IBM Open-Sources Power Chip Instruction Set
I have so many questions:<p>- Where can I get the ISA specification?[1]<p>- Where can I get a compiler?<p>- Is there a link to the "softcore model"?<p>With RISC-V you can start very simple and small (micro-controller) and work your way up in understanding and implementation to a very large core (application class). POWER is a monster of an architecture, designed more for "big iron". I guess that might limit the "hobbyist" factor RISC-V has.<p>1. This I think, all 1200 pages of it: <a href="https://openpowerfoundation.org/?resource_lib=power-isa-version-3-0" rel="nofollow">https://openpowerfoundation.org/?resource_lib=power-isa-vers...</a>
