The use of dynamically adjustable power supplies as a method to lower power dissipation in DSP is analyzed. Power can be reduced substantially without sacrificing performance in fixed-throughput applications by slowing the clock and lowering supply voltage instead of idling when computational workload varies. This can yield a typical power savings of 30–50%. If latency can be tolerated, buffering data and averaging processing rate can yield power reductions ofan order of magnitudein some… CONTINUE READING
