7.1.3
The number of states (system clock cycles) S for the execution of one slot is calculated with the
following conditions:
As an example, figure 7.4 shows the flow of a pipeline in which the IF (memory access for
instruction fetch) of instructions 1 and 2 are two cycles, the MA (memory access for data access)
of instruction 1 is three cycles and all others are one cycle. The dashes indicate the instruction is
being stalled.
S = (the cycles of the stage with the highest number of cycles of all instruction stages
contained in the slot). This means that the instruction with the longest stage stalls others with
shorter stages.
The number of execution cycles for each stage:
Note: Same stage of another instruction is being executed in same slot.
