Explain the fetch-decode-execute cycle

WebFetch: The first step of the machine cycle is the fetch step. The CPU retrieves the instruction from memory that needs to be executed. The instruction is stored in the instruction register (IR) of the CPU. Decode: Once the instruction is fetched, the CPU needs to decode it to understand what operation needs to be performed.

WebPipelining for Instruction Execution ° Same concept applies for instructions! ° We can pipeline instruction execution ° For MIPS, there are five classic steps: • FETCH: Fetch instruction from memory • DECODE: Read registers while decoding instruction • EXECUTE: Execute operation / calculate an address • MEMORY: Access an operand in memory (L/S) The instruction cycle (also known as the fetch–decode–execute cycle, or simply the fetch-execute cycle) is the cycle that the central processing unit (CPU) follows from boot-up until the computer has shut down in order to process instructions. It is composed of three main stages: the fetch stage, the decode stage, and the execute stage. rodger sharp https://dlwlawfirm.com
