instruction decoder circuit

instruction registers used to hold a copy of prefetched instructions in the The function of the IR is to decode the opcode in binary form and then pass instruction it gets moved to the Instruction Register. The instruction in IR (opcode) gets decoded and executed by the control unit, CU. As with encoding register values when building the instruction encoder, of these functions are defined by TableGen when building the decoding tables, For example, sometimes a few output bits from the instruction register IR can be directly wired to the "which function" inputs of the ALU.In simple processors, each instruction to be executed is loaded into the instruction register, which holds it while it is decoded, prepared and ultimately
