Sounds extremely subjective. i.e. it does not have my favored instructions or addressing modes, so it must be worse.

- smolder 2y agoMuch like juggling with your feet instead of hands is subjectively worse.
- snvzz 2y agoFrom a hardware perspective, juggling is better without flags and without unnecessary addressing modes. Neither are concepts RISC-V invented, but rather, adopted. Ideas that have been plenty tested out there, and proven beneficial. Large body of evidence trumps intuition and guesswork. Most of this is documented in the spec itself and/or in: Computer Architecture: A Quantitative Approach (John L. Hennessy, David A. Patterson)
- smolder 2y agoI just meant that it's somewhat unergonomic when dealing with the instruction set directly, FWIW. Thanks for the reference.
- jodrellblank 2y agoYou’re replying to the author of the post explaining why he would have to do more in software to emulate RISC-V than MIPS and that would be more effort and run slower, and you’re telling him “that’s extremely subjective”? How is that subjective?
- Dylan16807 2y ago"well known design deficiency" is the subjective part.
