تعريف program counter في الإنجليزية الإنجليزية القاموس.: A register that stores the address of the current (or next) instruction to be carried out by the processor; a 16bit register that places addresses on the bus to retrieve information stored within a program; Also PC A CPU register which holds the address of the next instruction to be executed The program counter is incremented after each byte of each instruction is fetched; A program counter is an integral part of a computer's Central Processing Unit It contains a reference to the memory address of the next instruction to be fetched, ready to be executed during the next fetch-execute cycle Immediately following an instruction fetch, the program counter is moved on to refer to the next instruction, before the current instruction is executed The normal sequential execution of a series of instructions may be changed by executing a branch instruction, which stores a new instruction address into the program counter; A register that counts in binary Its contents are the address of the next instruction to be fetched from the memory; (PC) the address of the next instruction to be executed in the code section of a program The CPU uses the PC to fetch the next instruction from memory; B3 3 3, p70; A special-purpose register in the CPU which contains the address of the next instruction to be fetched and executed; register that stores the number of the next command to be performed; A counter (known as a PC) that you can set to a selected line of source code or to an absolute value When you set the PC to a selected line, the PC points to the memory location at which the statement begins When you set the PC to an absolute value, the PC points to the line that contains the absolute address; This CPU register always contains the memory address where the next instruction to be performed by the CPU can be found Its contents is copied into the MAR before an instruction is fetched from the main memory While the instruction is being fetched, the Control Unit updates the contents of the PC so that it will again point to the next instruction to be performed; In a bytecode context, a variable that holds the address of the instruction currently being executed In the context of a microprocessor, the program counter is a special register that usually stores the position of the instruction currently being read For example, R15 is the program counter on ARM-based processors Due to the pipeline architecture, ARM2/3/6/7 cores have a PC that is two instructions ahead of the one being executed, and StrongARM cores have one that is (up to?) four instructions ahead; a register that contains the address of the next instruction to be executed
