VHDL: Programming by Example

CHAPTER 13

CPU: Synthesis Description

In this chapter, we further refine the CPU description and examine the RTL (Register Transfer Level) description of the CPU. The CPU is described by a number of lower-level components that are instantiated to form the CPU design. At the top of the CPU design is an architecture that instantiates all of the lower-level components to form the CPU. The CPU block diagram is shown in Figure 13-1.

Following is an implementation of this block diagram, shown by file cpu.vhd:
