For read-modify-write instructions, the pipeline effectively combines an embedded-load with a store
operation for a three-cycle execution time.
The pipeline timing diagrams of
instructions. In these diagrams, the x-axis represents time, and the various instruction operations are shown
progressing down the operand execution pipeline.
