Does anyone have an idea how bad is the ARM version? The reviews online say they did not fully adapt it from MIPS, and that the instruction set is partially made up instead of using the real one, which means listings won't work on real hardware.

- lostmsu 3y agoDoes RISC-V version include GPU? I am more inclined for ARM version since that's applicable to both all current Apple hardware and school Chromebooks.
- delta_p_delta_x 3y agoThe ISA doesn't really matter (at least, not between MIPS, ARMv8, and RISC-V) when you're first diving into computer organisation. That's why one book can be sold with three different ISAs. The overarching concepts are mostly the same: you have digital logic, IEEE-754, basic assembly (add, sub, and, not, xor, load, store, shift), pipelining and hazards, caches. Only afterwards do the differences between the ISAs come to play, when you have complex vector and ISA-specific instructions, superscalar pipelines, atomic instructions, etc.
- lostmsu 3y agoIt matters for engagement, e.g. if you can actually run examples painlessly.
- snvzz 3y agoThe open standard ISA RISC-V has the advantage there, with open source hardware implementations (like C906 and C910) and good tooling and simulators. RISC-V is rapidly building the strongest ecosystem.
