| 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. |
