摘要： Briefly, a processor and a method to calibrate a temperature reading of a digital thermometer. The calibration is done by using a first temperature value measured by an analog temperature sensor located at one point on the processor die and a second temperature value measured by a digital temperature sensor located at a second point of the processor die.

摘要： An interface between an accelerated graphics port graphics controller (AGP-GC) and a core controller to prevent entry into a low power state from interfering with transfers to or from the AGP-GC that have been requested but not completed. The core controller can communicate to the AGP-GC an intent to enter a low power state, while the AGP-GC can communicate to the core controller the busy status of the AGP-GC. When the AGP-GC receives notice of an intent to enter a low power state, it can stop issuing requests to the core controller. When the core controller detects that the AGP-GC is busy, the core controller can postpone entry into the low power state until the AGP-GC completes any requests that are in progress. In an alternate use of the interface, if the AGP-GC wishes to make a request during a low power state, it can signal the core controller of this need by indicating a busy status, which can trigger the core controller to initiate an exit from the low power state.

摘要： A method of creating a thermal influence table to describe thermal relationships between components in a system and use of the thermal influence table in a system is described. The thermal influence matrix may be generated dynamically for a system. The matrix may be used by a thermal management policy to enable a hot device to be cooled by power management of another device in the system.

摘要： A method and apparatus for efficient memory allocation and system management interrupt (SMI) handling is herein described. Upon waking a second processor in a multiple processor system, one may use a single SMI to initialize each processor, may use the location of a single default SMI handler as a wake-up vector to the second processor, and may patch an instruction pointer to a non-aligned address during the handling of the SMI with the second processor to forgo the traditional extra aligned memory allocation. In addition, one may use unified handler code to handle software generated SMIs on both the first and second processors and may use exit SMM directly after handling a hardware SMI to save execution time.

摘要： A demand-based method and system of central processing unit power management. The utilization of a central processing unit (CPU) during a sampling time interval is determined by measuring a time quantum within the sampling time interval during which a central processing unit clock signal is active within a processor core of the CPU. The total number of cycles of the central processing unit clock signal that are applied to the processor core and the period of the central processing unit clock signal are used to determine the time quantum. The utilization may then be expressed in terms of a ratio of the time quantum to the total time interval and used to select a processor performance mode. The CPU is then operated in the selected processor performance mode.

摘要： In one embodiment of the invention, an embedded controller receives an interrupt command and a query number from a system management interrupt (SMI) handler. The embedded controller generates a system control interrupt (SCI) in response to the interrupt command. A driver that receives the SCI issues a query command to the embedded controller. A routine associated with the query number is invoked in response to the query command.

摘要翻译： 加速图形端口图形控制器（AGP-GC）和核心控制器之间的接口，以防止进入低功率状态，干扰来自AGP-GC的请求但尚未完成的传输。 核心控制器可以与AGP-GC进行通信，意图进入低功率状态，而AGP-GC可以与核心控制器通信AGP-GC的忙碌状态。 当AGP-GC接收到进入低功率状态的意图时，可以停止向核心控制器发出请求。 当核心控制器检测到AGP-GC正忙时，核心控制器可以推迟进入低功率状态，直到AGP-GC完成任何正在进行的请求。 在接口的替代使用中，如果AGP-GC希望在低功率状态期间发出请求，则可以通过指示忙状态来向核心控制器通知该核心控制器，这可以触发核心控制器发起退出 低功率状态。
