EXAMPLE 4-2:

INSTRUCTION PIPELINE FLOW

EXAMPLE 4-3:

INSTRUCTIONS IN PROGRAM MEMORY

Note:

All instructions are single cycle, except for any program branches. These take two cycles, since the fetch instruction is

“flushed” from the pipeline while the new instruction is being fetched and then executed.
