Is there a point where a CPU stops being RISC and starts being CISC, or are there fundamental differences in the two?

- jasonwatkinspdx 6y agoThe key distinction is addressing modes usable in instructions. Even RISC architectures that spiral into complexity tend to keep the basic separation of LOAD/STORE vs other instructions, while CISC almost always allows flexible arguments of registers, immediates, or a variety of memory address expressions to be used with most instructions.
