I would say that the CISC philosophy is about lowering the complexity at the software level to raise it at the circuitry level while the RISC philosophy is the inverse. Philosophies that you can apply not only to CPUs but also to virtual machines. Today ARM SoC are adding more and more ASICs (AI, RayTracing, Photo post processor, GPU, ...) so instead of dealing with a complex ISA you now have to deal with multiple simpler ISAs.
- spear 6y agoI think that's a misleading way of looking at things. There is no "CISC philosophy". RISC designs came out as a new way of doing things and existing designs were called CISC for contrast. It's not like there were two schools of thought that were developed at the same time and the CISC designs intentionally rejected RISC philosophies.
