Pipeline Method
The program controller implements a four-level pipeline architecture. In the operation of
the pipeline, concurrent fetch, decode, operand fetch and execution occur. Thus, during
a given cycle up to four different instructions are being processed, each at a different
stage of pipeline. The pipeline is an “interlocking” type.
Figure 10 shows the pipeline operation for sequential single-cycle instructions: The
instruction n is executed in cycle four. During this cycle instruction n + 3 is pre-fetched,
instruction n + 2 is decoded and the operand needed at instruction n + 1 is fetched.
For multiple-cycle instructions, the pipeline structure may differ but these details are
beyond the scope of this document.
