Abstract
In an embodiment, a system may support a 'coast mode' in which the power management unit (PMU) that supplies the supply voltage to an integrated circuit is disabled temporarily for certain modes of the integrated circuit. The integrated circuit may continue to operate, consuming the energy stored in capacitance in and/or around the integrated circuit. When coast mode is initiated, a time interval for coasting may be determined. When the time interval expires, the PMU may re-enable the power supply voltage.
