Pipelining

• One instruction/result every cycle (ideal)

  • Not in practice because of hazards

• Increase throughput

  • Throughput = number of results/second

• Improve speed-up

  • In the ideal case, if n stages , the speed-up will be close to n. Can’t make n too large: load balancing between stages & hazards

• Might slightly increase the latency of individual instructions (pipeline overhead)
