Question

onsider a fairly standard 5-stage pipeline: Fetch; Decode; Execute;
Memory; Writeback. Let the processor be a nice, simple RISC single-cycle
machine. The instructions below are executed. The branch should be
taken — however, this processor does no prediction and always assumes
a fall-through.

Draw a Gantt chart for this and determine the branch
penalty.
 (I have been deliberately vague about some of the details here,
as I want you to think about what makes sense in terms of when the
branch outcome is known and branch target computed.)
