Detailed explanation-1: -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-2: -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.
Detailed explanation-3: -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 operation, the PC points to the next instruction that will be read at the next cycle.
