1. A system comprising: a context file to store a plurality of contexts, each context of the plurality of contexts corresponding to a different power mode of an electronic system and each context of the plurality of contexts comprising bit slices; and a domain control device including multiple control signal units each configured to receive from the context file a different portion of the bit slices of a context and to use the different portions of the bit slices of the context to generate corresponding control signals, each control signal corresponding to a power mode operation of the electronic system, wherein the electronic system is configured to transition to the power mode corresponding to the bit slices of the context responsive to the control signals.
