Abstract
In an embodiment, an operating point controller for two or more circuit regions in an integrated circuit is discussed. The OPC is configured to both i) set a resource state, including operating voltage and operating frequency, for each of those circuit regions, and ii) identify events to initiate transitions between two or more operating points for a given circuit region. The operating point controller is also configured to manage transitions between operating points for the two or more circuit regions on the integrated circuit. The operating point controller is a hardware based machine implemented in logic rather than software operating on a CPU processor.
