Each computer's CPU can have different cycles based on different instruction sets, but will be similar to the following cycle: Fetch stage: The next instruction is fetched from the memory address that is currently stored in the program counter and stored into the instruction register. At the end of the fetch … See more 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 … See more The program counter (PC) is a special register that holds the memory address of the next instruction to be executed. During the fetch stage, the address stored in the PC is copied into the memory address register (MAR) and then the PC is incremented in … See more The decoding process allows the CPU to determine what instruction is to be performed so that the CPU can tell how many operands it needs to fetch in order to perform the instruction.
