Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The program counter, or PC (also called the instruction pointer, or instruction address register, or just part of the instruction sequencer in some computers) is a processor register that indicates where the computer is in its instruction sequence. Depending on the details of the particular computer, the PC holds either the address of the instruction being executed, or the address of the next instruction to be executed.In most processors, the instruction pointer is incremented automatically after fetching a program instruction, so that instructions are normally retrieved sequentially from memory, with certain instructions, such as branches, jumps and subroutine calls and returns, interrupting the sequence by placing a new value in the program counter.
