Detailed explanation-1: -To achieve this interleaving, the CPU relies on a clock that generates a series of regular pulses. Each pulse represents a fixed interval of time, known as a clock cycle. The CPU uses these clock cycles to coordinate its internal operations, including the fetch and execution cycles.
Detailed explanation-2: -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 order to “point” to the memory address of the next instruction to be executed.
Detailed explanation-3: -The fetch-execute cycle (also known as fetch-decode-execute cycle) is followed by a processor to process an instruction . The cycle consists of several stages. The memory address held in the program counter is copied into the MAR . The address in the program counter is then incremented-increased-by one.
Detailed explanation-4: -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.
