Abstract
A power management system for managing power consumption of a digital signal processor (DSP) that implements a protection system, the power management system comprising: a power management block configured to: detect a parameter indicative of a power of an input signal to the DSP; compare the detected parameter to a threshold; and responsive to a determination that the detected parameter is less than the threshold, cause one or more processing blocks of the DSP to enter a low power mode of operation.
