POWER AND PERFORMANCE MANAGEMENT OF ASYNCHRONOUS TIMING DOMAINS IN A PROCESSING DEVICE

摘要

A processing device includes a producing processor unit in a first timing domain and a consuming processor unit in a second timing domain that is asynchronous with the first timing domain. A queue is used to convey data between the producing processor unit and the consuming processor unit. A system management unit is to modify one or both of an operating frequency or an operating voltage of one or both of the producing processor unit or the consuming processor unit based on a rate of change of a fullness of the queue.
