Abstract:
A power controller can set the power state of a processor bridge based on which processor modules are in a communicative state. In addition, for a power state where selected processor modules are expected to be non-communicative, the power controller can set the supplied voltage to have a reduced voltage guard band as compared to other power states. These power management techniques can reduce the power consumed by the processor.
