Instruction-level taxonomies
After the commoditization of memory, attention turned to optimizing CPU performance at the instruction level. Various methods of speeding up the fetch-execute cycle include:
- designing instruction set architectures with simpler, faster instructions: RISC as opposed to CISC
- Superscalar instruction execution
- VLIW architectures, which make parallelism explicit
