Pipelining: Some definitions

• Latency: Time to perform a computation

  • Data in to data out

• Throughput: Input or output data rate

  • Typically the clock rate

• Combinational delays drive performance

  • Define d ? delay through slowest combinational stage n ? number of stages from input to output
    • Latency ? n × d (in sec)
    • Throughput ? 1/d (in Hz)
