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. WebPhase 1 – Instruction fetch. The Control Unit generates the control signals that copy an instruction byte from the memory into the Instruction Register, IR. The address of this instruction is in the Program Counter, PC.
