Dynamic voltage and frequency scaling transition synchronization for embedded systems
Abstract:
Methods and apparatuses are provided that allow for the synchronization of an operating point transition in an embedded system environment. Identification of an upcoming operating point transition, operating point transition constraints, and maximum parking latency parameters is provided. Then, an ordering of seizing bus activity as well as an ordering of resuming bus activity is determined. The operating point transition is then implemented using the determined ordering. Simulation and determination of change of successfully completing operating point transition prior to initiating and while the transition is pending are also provided.
