Fetch-decode-execute cycle of a cpu
WebConcept note-4: -Explanation: The fetch execution cycle refers to the execution of instructions by the CPU. This is a multi-step process in which instructions are fetched, decoded, executed, and then stored. The result of this cycle allows an instruction to be executed by the CPU allowing the process cycle to continue. WebAn instruction cycle (sometimes called fetch-decode-execute cycle) is the basic operation cycle of a computer. It is the process by which a computer retrieves a program instruction from its memory, determines what actions the instruction requires, and …
