Abstract: A method for dynamic clock and voltage scaling (DCVS) in a central processing unit (CPU) subsystem of a wireless communication device. The method may be implemented by a DCVS controller of the wireless communication device. The DCVS controller monitors data packets communicated by the CPU subsystem over a wireless local area network (WLAN) and determines one or more metrics of the data packets communicated by the CPU subsystem. The DCVS controller then dynamically configures an operating frequency of one or more hardware resources of the CPU subsystem based at least in part on the one or more metrics. The one or more metrics may include, for example, a packet rate, payload size, aggregation factor, packet size, or number of descriptors associated with the data packets.
