Detailed explanation-1: -A machine cycle consists of the steps that a computer’s processor executes whenever it receives a machine language instruction. It is the most basic CPU operation, and modern CPUs are able to perform millions of machine cycles per second. The cycle consists of three standard steps: fetch, decode and execute.
Detailed explanation-2: -The CPU works by following a process known as ‘fetch, decode and execute’. The CPU fetches an instruction from memory, decodes this instruction and then executes it. The CPU carries out this cycle continuously, millions of times per second.
Detailed explanation-3: -Fetch. In the fetch cycle, the control unit looks at the program counter register (PC) to get the memory address of the next instruction. It then requests this instruction from main memory and places it in the instruction register (IR). Decode.
