Bus clock frequency scaling for a bus interconnect and related devices, systems, and methods

Abstract

Bus clock frequency scaling for a bus interconnect and related devices, systems, and methods are disclosed. In one embodiment, the bus interconnect comprises an interconnect network configurable to connect a master port(s) to a slave port(s). A bus interconnect clock signal clocks the interconnect network. The controller is configured to receive bandwidth information related to traffic communicated over the master port(s) and the slave port(s). The controller is further configured to scale (e.g., increase or decrease) the frequency of the bus interconnect clock signal if the bandwidth of the master port(s) and/or the slave port(s) meets respective bandwidth condition(s), and/or if the latency of the master port(s) meets a respective latency condition(s) for the master port(s). The master port(s) and/or slave port(s) can also be reconfigured in response to a change in frequency of the bus interconnect clock signal to optimize performance and conserve power.
