Pipelining: What and why

• What?

  • Subdivide combinational logic
  • Add registers between logic blocks

• Why?

  • Increase clock speed
    • Reduce logic delays
    • But…takes a few cycles to fill the pipe
  • Trade latency for throughput
    • Latency worse
    • Throughput better
  • Increase circuit utilization
    • Simultaneous computations
