- Instruction_register abstract "In computing, an instruction register (IR) is the part of a CPU's control unit that stores the instruction currently being executed or decoded. In simple processors each instruction to be executed is loaded into the instruction register which holds it while it is decoded, prepared and ultimately executed, which can take several steps. Some of the complicated processors use a pipeline of instruction registers where each stage of the pipeline does part of the decoding, preparation or execution and then passes it to the next stage for its step. Modern processors can even do some of the steps out of order as decoding on several instructions is done in parallel.Decoding the opcode in the instruction register includes determining the instruction, determining where its operands are in memory, retrieving the operands from memory, allocating processor resources to execute the command (in superscalar processors), etc.The output of IR is available to control circuits which generate the timing signals that control the various processing elements involved in executing the instruction.In the Instruction cycle, the instruction is loaded into the Instruction register after the processor fetches it from the memory location pointed by the Program counter.".
