- Processor design techniqueCPU microcode is a processor design technique that interposes a layer of computer organization between the CPU hardware and the programmer-visible instruction set architecture of the computer1. It forms the translation layer between higher level standard CPU instructions and the lower-level operations specific to that CPU2. Microcode is not a generic term for all firmware that is loaded onto a device at boot, but rather a specific feature of CPUs2.Learn more:โThis summary was generated using AI based on multiple online sources.
