Design techniques for high-performance, energy-efficient control logic

This paper investigates delay, power and area of critical components in designing energy-efficient control logic. To improve performance and energy efficiency, a split-slave dual-path (SSDP) register is proposed which improves the energy efficiency of the prior art by 30%. For multiplexers (MUX) three MUXes are proposed and compared to existing solutions. The proposed MUXes improve performance by 50% or power by 22%. The impact of scaling supply voltage alone and scaling threshold voltage with supply voltage on delay and power is also examined.
