The fetch-decode-execute cycle is followed by a processor to process an instruction. The cycle consists of several stages. Depending on the type of instruction, additional steps may be taken: If ...

Instructions Per Cycle (IPC) is a key aspect of a CPU’s design, ... The steps needed to execute an instruction can be broadly defined as: fetch, decode, execute, and write-back.

Most general purpose computers are based on von Neumann architecture. This includes using the fetch-decode-execute cycle to process program instructions. Computer performance depends on cache size ...

The processor's decode unit features two hardware decoders and one microcode decoder, and can decode up to two instructions per cycle. Silverthorne block diagram. Source: Intel ...
