How does the fetch-decode-execute cycle work
WebJul 14, 2024 · The fetch-decode-execute cycle is a process that the CPU repeats continuously in order to execute instructions. To complete each cycle, the CPU goes through three main stages. Fetches a program instruction from the main memory. Decodes the instruction, i.e. works out what needs to be done. What is instruction decode? WebExpert Answer. A) Suppose a MIPS processor uses the simple 5-stage pipeline, where the stages are instruction fetch (IF), instruction decode and operand fetch (ID), execute and calculate address (EX), memory access (M), and write back (WB). In addition, suppose that: - The instruction and data cache are unified and can only support one read or ...
