Instead of simply moving to the next address, the counter is loaded with a new target address specified by the jump instruction. During the decode stage, the control unit interprets the instruction, and finally, the execute stage carries out the command.
Program Counter Sequential Processing Logic and Its Role in CPU Execution
Defining the Program Counter The program counter, often abbreviated as PC, is a specific CPU register that holds the memory address of the next instruction the processor is scheduled to execute. Without this mechanism, a CPU would lack the directional awareness necessary to process code sequentially, jumping erratically through memory and crashing any running application.
In this scenario, the program counter functions as a simple incrementer. To manage this, the processor pushes the current value of the program counter—the address of the instruction immediately following the call—onto the stack.

At these moments, the program counter is dynamically modified. It is the foundation of procedural programming and ensures logical flow.
