Program Counter A program counter is a register in a computer processor that contains instruction’s address that is executed at the current time. The program counter increases its stored value by 1, as each instruction gets fetched. It is located inside the microprocessor and stores the memory address of next instruction to be executed. Instruction Pointer An instruction register is the part of a Central Processing Unit’s (CPU) control unit that holds the instruction that is to be executed currently. The CPU decodes the instruction and then executes it. The function of an instruction register is to hold the currently queued instruction for use.
