Abstract
An embedded processor system including at least one gated power unit including an internal ROM and a power controller that provides one or more gated power signals to selectively provide power to each gated power unit. The power controller provides a gated clock signal to the embedded processor to selectively control power consumption of the processor. The power controller powers down each gated power unit after freezing the processor and then powers up each gated power unit before reactivating the processor. The embedded processor system may include isolation circuitry, such as clamp circuitry or the like, that is operative to minimize current flow into each gated power unit when powered down. The gated power units may include a static function. The ROM of an embedded ROM-based microprocessor system is powered down when the microprocessor is idle to reduce or otherwise eliminate intrinsic leakage.
