Describe the concept of dynamic branch prediction in pipelining. How does it work, and why is it crucial for improving instruction throughput?
Expert Solution
Step 1: Define pipelining.
Pipelining is a strategy employed in computer processor design to boost the effectiveness of instruction execution. It achieves this by dividing the processing of instructions into a sequence of stages, with each stage dedicated to a particular operation on the instruction. Consequently, numerous instructions are concurrently in various stages of processing. This method facilitates the processor in overlapping and executing instructions in parallel, culminating in enhanced throughput and overall performance.
