Device, system and method to determine a power mode of a system-on-chip

Abstract:

Techniques and mechanisms for identifying a power state to be provided with an integrated circuit (IC). In an embodiment, evaluator circuitry of a system-on-chip is programmable based on multiple criteria which are each for a different respective power mode. Programming of the evaluator circuitry enables concurrent evaluations each to determine, for a different respective power mode, whether a detected state of the IC is able to accommodate said power mode. Results of the evaluations are communicated, in parallel with each other, to circuitry which selects one such power mode based on relative priorities of the power modes with respect to each other. In another embodiment, the evaluator circuitry comprises an array of circuit cells which are configurable each to perform a different respective evaluation based on a corresponding combination of a test condition and a detected condition of the IC.
