Explain the delay optimisation techniques and power optimisation techniques

Question

Accepted Answer

Delay optimisation techniques focus on reducing the time taken for signal propagation, while power optimisation techniques aim to reduce power consumption.

Delay optimisation techniques include pipeline insertion, clock gating, and buffer insertion.
Power optimisation techniques include voltage scaling, power gating, and clock gating.
Both delay and power optimisation techniques involve trade-offs between performance and power consumption.
Examples of delay optimisation techniques:
- Pipeline insertion breaks down a complex logic into smaller stages to reduce overall delay.
- Clock gating disables clock signals to unused parts of the circuit to save power.
Examples of power optimisation techniques:
- Voltage scaling adjusts the operating voltage of the circuit to reduce power consumption.
- Power gating completely shuts off power to unused parts of the circuit to save power.
