String Operations! Amazing. Putting the emphasis on “Complex” in CISC.
- userbinator 4y agoARM, which is decidedly considered RISC, has STM/LDM. It also uses microcode and Ken has not surprisingly written about it too: http://www.righto.com/2016/02/reverse-engineering-arm1-processors.html http://www.righto.com/2016/02/reverse-engineering-arm1-proce...
- monocasa 4y agoFWIW, there's a lot of people that consider ARM a hybrid RISC/CISC, among other reasons, because of the presence of LDM/STM. Yeah, it literally has RISC in the name, but the SuperFX is called RISC by it's creators as well, but it's about as far aawy as you can get. RISC was a buzzword to the point that it's still a bit muddled to this day 40 years later.
