The microprocessor can only interpret machine code instructions specified in its instruction set. While running a machine language program, the program counter or instruction pointer register holds the offset of the address of the next instruction to be executed. The segment base address is held in ...
TheInstruction Register(IR) in a simplemicroprocessoris a simple register with enough bits for the address and opcode combined. For example, if the address requires 8 bits, and the opcode also requires 8 bits, then the Instruction Register needs to be 16 bits wide (8 + 8). If the output...
Instruction Format of electronic computers; the number of addresses in an instruction. The instruction format is determined by the nature and coherence of the operations being carried out, the length of the machine’s word format, and the capacity and structure of direct-access storage. Instruction...
