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
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.
