ABSTRACT:
A system controller manages communication of data between a microprocessor, a memory and input/output controllers in a computer. A power management controller is operative upon occurrence of microprocessor inactivity indications to disable power to the microprocessor without disabling power to the input/output controllers. Operations of the power management controller is sequenced by a plurality of programmable registers, which are programmed by signals received either from a main data bus connected to the system controller, and other units, such as input/output controllers, a keyboard controller and from a memory, or a local data bus connected between at least one of the units and the system controller.
