Thanks a lot for these. Which CPU architecture would you suggest to begin with first?

  That's a good question. Probably either RISC-V or ARM. MIPS is interesting, but I'm not sure that it has much of a future. OTOH, there's plenty of choice and availability of both ARM and RISC-V based computers to play around with. RISC-V is newer and probably still evolving more rapidly, so I guess you'd want to weigh whether you consider that a pro or a con. For me personally, I have recently gotten really interested in RISC-V, so I lean that way a little bit. But that's more personal preference than anything concrete I can really cite.

    >RISC-V is newer and probably still evolving more rapidly Yet RVA20(RV64GC) and RVA22 are set on stone.

      That's fair. But there's still changes going on in terms of extensions, and then there's the implementation level stuff (both hardware and software). So I guess I was really thinking more in terms of the overall ecosystem than just the instruction set.
