4.7 Instruction-Set and Instruction Execution Process. The instruction-set and the process by which each instruction is executed are usually given together in a single definition. This process is called Instruction_ execution in all the ISP descriptions in this book. It usually includes the definition of the conditions for execution, the instruction (i.e., its operation code), the name of the instruction, its mnemonic name, and the process for execution.
