摘要： Multiple data transfer requests can be merged and transmitted as a single packet on a packetized bus such as a PCI Express (PCI-E) bus. In one embodiment, requests are combined if they are directed to contiguous address ranges in the same target device. An opportunistic merging procedure is advantageously used that merges a first request with a later request if the first request and the later request are mergeable and are received within a holdoff period that is dynamically determined based on a level of bus activity; otherwise, requests can be transmitted without merging.
摘要翻译：多个数据传输请求可以在诸如PCI Express（PCI-E）总线的分组化总线上合并并发送为单个数据包。在一个实施例中，如果它们被引导到相同目标设备中的连续地址范围，则组合请求。有利地使用机会主义合并过程，如果第一请求和后期请求可合并并且在基于总线活动级别动态确定的保留期间内被接收，则将第一请求与稍后的请求合并; 否则，可以在不合并的情况下传送请求。

摘要： Circuits, methods, and apparatus that provide transactions to wake an external device from a low-power state before a data transfer. This prevents an interruption that would be caused if the external device exited the low-power state during the data transfer. One example monitors a need for data by a first device. At a predetermined time before data is needed, the first device sends a transaction to a second device. The transaction is intended to wake the second device from a low-power state. If the first device has information to indicate that the second device is not in a low-power state, this transaction can be skipped. The first device then requests data. Later transactions to the second device do not result in the second device exiting the low-power state and therefore do not interrupt or cause delays in the data transfer.
摘要翻译：在数据传输之前提供事务以将外部设备从低功率状态唤醒的电路，方法和装置。这防止了在数据传输期间外部设备退出低功率状态时会导致的中断。一个示例监视第一设备对数据的需求。在需要数据之前的预定时间，第一设备将事务发送到第二设备。该事务旨在将第二个设备从低功耗状态唤醒。如果第一设备具有指示第二设备不处于低功率状态的信息，则可以跳过该事务。第一个设备然后请求数据。到第二个设备的后期事务不会导致第二个设备退出低功耗状态，因此不会中断或导致数据传输延迟。

摘要： The present invention systems and methods facilitate secure communication of information between devices. A present invention system and method can enable secure communication of proprietary content in a HDCP compliant configuration. In one embodiment, a high definition content protection key secure management method is utilized to enable efficient and secure storage of a HDCP key. A high definition content protection key value is received. The high definition content protection key is encrypted utilizing a secure key value, wherein the secure key value is not accessible via an external port. In one exemplary implementation, the secure key is stored in fuses included in a processing unit. The results of said encrypting in a memory (e.g., a BIOS memory, flash memory, etc.).

摘要： The present invention pertains to a computer chassis with improved airflow to reduce the occurrence of trapped air pockets and increase heat transfer from components within the chassis. The computer chassis includes a plurality of chambers, wherein each of the chambers is separated by a partition. The partitions are operable to reduce the occurrence of trapped air pockets and increase heat transfer from components of the chassis by causing air to flow through each of the chambers. The computer chassis further includes at least two air vents, wherein each of the chambers is coupled to at least one of the at least two air vents through which air enters the chamber, and wherein each of the chambers is coupled to at least one of the at least two air vents through which air exits the chamber.

摘要： A computer system that employs Peripheral Component Interconnect Express (PCIe) links includes devices that generate a PCIe packet having a header portion that is smaller than the header portion for a conventional PCI packet. The devices may be an endpoint device, such as a graphics processor, and a chipset, such as a root-complex. The reduced size header improves the bus throughput efficiency of the computer system and reduces power requirements for the computer system.
