Question

What are control hazards, and how can they affect the performance of a pipelined processor? Discuss techniques like branch prediction to address control hazards.

Expert Solution
Step 1: Control Hazards Overview:

Control hazards are a type of hazard found in pipelined processors that arises from branch instructions.

These hazards can impact a processor's performance by causing stalls in the pipeline and reducing the overall instruction throughput.

Control hazards occur when the processor meets a branch instruction, and it is uncertain until the execution stage of the pipeline whether the branch will be taken or not.
