The instruction set you saw in Figure 5-19 is very small, compared to those of most CISC processors. Often, it can be easier to comprehend a new idea when you begin by looking at a simple model. This Web site uses a simple chip to give insight into the structure and function of instruction sets. Here, you can not only read the instruction set of a simple processor, but also learn what it took to build the processor. This Web page displays the instruction set for the Motorola 68000 chip.
