A processor's energy consumption can be reduced by compressing values (data and addresses) that flow through a processor pipeline and gating off portions of data path elements that would otherwise be used for computing non-significant bits. An approach for compressing all values running through a processor is proposed and evaluated. For the SpecInt2000 benchmarks the best compression method achieves energy savings of more than 20 percent and a peak power reduction of 18 percent.
