      What is RISC? https://danluu.com/risc-definition/ … Hint: it's not about the number of instructions.pic.twitter.com/2YLL4tBWkS

      Periodic reminder that basically every "RISC is obsolete" / "RISC is unscalable" article is based on a faulty assumption. RISC has never been about not having instructions like FJCVTZS.pic.twitter.com/1ozoH5MWgL

      "I wish I could also be excited, but to me, this is just a reminder that RISC architectures are fundamentally unscalable, and inevitably stop being RISC as soon as they need to be fast. People still call ARM a “RISC” architecture despite ARMv8.3-A adding a FJCVTZS instruction, which is “Floating-point Javascript Convert to Signed fixed-point, rounding toward Zero”. Reduced instruction set, my ass."

          No worries, a lot of people had the same problem! I think new Twitter makes it much harder to follow conversations? I didn't used to get this kind of response to multi-part tweets but it now happens all the time. I wonder if confused replies make the engagement #s look good? 🙃
