Methods and apparatus for limiting a number of current changes while clock gating to manage power consumption of processor modules

摘要

A dispatch module implemented in at least one of a memory or a processing device is operatively coupled to multiple processing modules, each having a first clock configuration and a second clock configuration. The dispatch module, at a first time, changes a first processing module included in the multiple processing modules from a first clock configuration to a second clock configuration. The dispatch module prohibits, at a second time within a predetermined time period and after the first time, a second processing module included in the multiple processing modules from changing from the first clock configuration to the second clock configuration if an indicator associated with a number of changes of the multiple processing modules between a first clock configuration and a second clock configuration within the predetermined time period and prior to the second time satisfies a criterion.

1. An apparatus, comprising:
a dispatch module implemented in at least one of a memory or a processing device, the dispatch module configured to be operatively coupled to a plurality of processing modules each having a first clock configuration and a second clock configuration, the dispatch module configured to change, at a first time during a predetermined time period, a processing module from the plurality of processing modules from the first clock configuration to the second clock configuration, the dispatch module configured to prohibit a change in clock configuration of each processing module from the plurality of processing modules from the first clock configuration to the second clock configuration at a second time after the first time and within the predetermined time period if an indicator associated with a number of clock configuration changes between a first clock configuration and a second clock configuration within the predetermined time period satisfies a criterion, the criterion being based on a threshold number of times an electric current changes, within the predetermined time period, for at least one of a chip package associated with the dispatch module or a power supply associated with the dispatch module.
