Abstract

Leakage power consumption may be reduced in computers and other devices by providing a state where clocks are off and a low supply voltage is provided to the processor. This voltage may be sufficiently low to prevent adverse consequences while dramatically reducing leakage current. In addition, caches may be flushed to reduce the soft error rate.
