Methods and apparatus for clock gating processing modules based on hierarchy and workload

Abstract:

A dispatch module implemented in at least one of a memory or a processing device is operatively coupled to a first processing module and a second processing module. The first processing module has a priority higher than a priority of the second processing module. The dispatch module includes a workload counter associated with the first processing module to provide an indication of a workload at the first processing module. The dispatch module initiates a clock signal at the second processing module only if the indication of the workload at the first processing module satisfies a criterion. The dispatch module sends a data unit to the second processing module for processing only if the indication of the workload at the first processing module satisfies a criterion.
