Question

The performance of a pipelined processor suffers if

• A. the pipeline stages have different delays
• B. the pipeline stages share hardware resources
• C. consecutive instructions are dependent on each other
• D. All of the above

Answer 1

The correct option is D All of the above

Hazards are caused due to dependencies.

Different dependencies in pipelined processor are:

1. Structural dependency : The pipeline stages have different delays.

2. Control dependency : Consecutive instructions are dependent as each other.

3. Data dependency : The pipeline stages share hardware resources.
