USER’S MANUAL

Figure 4-4 Basic Instruction Formats

4.10 Execution Model

This description builds up a conceptual model of the mechanism the CPU16 uses to

fetch and execute instructions. The functional divisions in the model do not necessarily

correspond to physical subunits of the microprocessor.

As shown in Figure 4-5, there are three functional blocks involved in fetching, decod-

ing, and executing instructions. These are the microsequencer, the instruction pipe-

line, and the execution unit. These elements function concurrently. All three may be

active at any given time.
