What is a branch delay slot?
Think about what happens immediately after a branch instruction.
Why can’t all instructions be executed in delay slots?
Consider the relationship of instructions in programming flow.
What is the primary benefit of using branch delay slots?
Think about the role of delay slots in handling control hazards.
True or False: Delay slots can always be filled with any instruction.
Understand the dependency rules regarding branch outcomes.
Consider a pipeline where a branch instruction and three following instructions are in contention for execution. Determine the optimal use of a delay slot and explain the rationale.
Evaluate dependencies among instructions before scheduling.
Given a simple assembly code snippet with conditional branches, refactor it to effectively utilize delay slots. Discuss potential pitfalls.
Check if the inserted instructions depend on the branch results.
