USER’S MANUAL
The microsequencer controls the order in which instructions are fetched, advanced
through the pipeline, and executed. It increments the program counter and generates
multiplexed external tracking signals IPIPE0 and IPIPE1 from internal signals that
control execution sequence.
The pipeline is a three stage first in, first out buffer (FIFO) that holds instructions while
they are decoded and executed. Depending upon instruction size, as many as three
instructions can be in the pipeline at one time (single-word instructions, one held in
stage C, one being executed in stage B, and one latched in stage A).
The execution unit evaluates opcodes, interfaces with the microsequencer to advance
instructions through the pipeline, and performs instruction operations.
