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 order to "point" to the memory address of the next instruction to be executed. The CPU then takes the instruction at the memory address described by the MAR and copies it into the memory data register (MDR). The MDR also acts a… WebSep 25, 2024 · By definition, if an instruction fetch is delayed for some reason, the execution of that instruction (and subsequent instructions) must be delayed.
