摘要： Systems and methods for discrete power control of components within a computer system are described herein. Some illustrative embodiments include a system that includes a subsystem with a plurality of components (configurable to operate at one or more power levels), a control register (coupled to the plurality of components) including a plurality of bits (each uniquely associated with a one of the plurality of components), and a power controller coupled to, and configurable to cause, the plurality of components to operate at the one or more power levels. The power controller asserts a signal transmitted to the subsystem, commanding the subsystem to transition to a first power level. A first of the plurality of components, associated with an asserted bit of the control register, operates at a second power level corresponding to a level of power consumption different from that of the first power level indicated by the power controller.
