摘要： A communication system is described providing for access to registers over a control register access bus. The system includes one or more core units including one or more addressable core registers, wherein the units are coupled to the communication bus. The system also includes one or more core clusters (CCLUSTERs) coupled to the one or more core units through the communication bus. The CCLUSTERs provide one or more gateways for transactions to and from the one or more core units. The system also includes a request ordering and coherency (ROC) unit coupled to the CCLUSTERs through the communication bus that is configured for scheduling transactions relating to the registers onto the communication bus. The system also includes the one or more addressable registers that are located in the ROC unit, the CCLUSTERs, and the one or more core units.

摘要： A system and method for power management by providing advance notice of events. The method includes snooping a register of an operating system timer to determine a timer period associated with a scheduled event. A unit of a computer system is identified that is in a low power state. A wake up latency of the unit is determined that is based on the low power state. An advance period is determined based on the wake up latency. An advance notice of the operating system timer is triggered based on the timer period and the advance period to wake up the unit.
