摘要： To reduce prefetch overshoot when prefetching partial data sets along the path from input-output bus to system memory, a prefetch field is used to communicate the amount of data that a prefetching entity upstream may prefetch. Utilizing a prefetch field in such a manner reduces the fetching of unneeded data past the end of the requested data, resulting in overall increased system performance.

摘要： A method for accessing a configuration data space for a device connected to a processor through an interconnect includes receiving a request from the processor to access the processor's addressable space. The request is generated in response to receiving an instruction intended to access the device's configuration data space. A map between the device's configuration data space and the processor's addressable space is accessed, the map having previously mapped the device's configuration data space to one or more pages of the processor's addressable space. Using the map, the request from the processor is translated into a configuration cycle on the interconnect to access the device's configuration data space.

摘要： One embodiment involves having a processor writing disk drive command information for a number of data transactions to cacheable system memory. The processor then performs a single write transaction to a disk drive host controller. The disk drive host controller then causes a DMA transfer to occur which reads the command information located in system memory and stores the command information in a queue. Once the host controller has the command information, it programs the disk drive with information corresponding to a queue entry over a serial interconnect. The disk drive signals an interrupt after it processes the command information. The disk drive host controller does not forward the interrupt to the processor, but services the interrupt itself. The disk drive host controller reads from the disk drive to determine the disk drive status. The disk drive can signal that it is ready to execute the programmed command, or it can signal that it is not ready to perform the programmed command but is ready to receive additional command programming information corresponding to another queue entry, or it may signal that it is ready to execute a previously programmed command. The disk drive host controller then performs the required operations using the information stored in the queue without involving the processor. Because the processor is only involved in setting up a command block in system memory and in signaling the disk drive host controller that the command block is ready for reading, the processor is freed up to perform other tasks and overall system performance is improved.
摘要翻译：一个实施例涉及将处理器将用于多个数据事务的磁盘驱动器命令信息写入可高速缓存的系统存储器。然后，处理器对磁盘驱动器主机控制器执行单个写入事务。然后，磁盘驱动器主机控制器发生DMA传输，其中读取位于系统存储器中的命令信息，并将命令信息存储在队列中。一旦主机控制器具有命令信息，它将通过串行互连对具有与队列条目相对应的信息来对磁盘驱动器进行编程。磁盘驱动器在处理命令信息后发出中断信号。磁盘驱动器主机控制器不会将中断转发给处理器，而是自动为中断服务。磁盘驱动器主机控制器从磁盘驱动器读取以确定磁盘驱动器状态。磁盘驱动器可以指示它准备好执行编程的命令，或者它可以发信号通知它没有准备好执行编程的命令，但是准备好接收与另一个队列条目相对应的附加命令编程信息，或者它可以发信号准备执行以前编程的命令。然后，磁盘驱动器主机控制器使用存储在队列中的信息来执行所需的操作，而不涉及处理器。由于处理器仅涉及在系统存储器中设置命令块，并且在向盘驱动器主机控制器发信号通知命令块准备好进行读取时，处理器将被释放以执行其他任务，并提高整体系统性能。

摘要： A system and method to determine a port that a codec is attached is disclosed. An access will be attempted to a codec, and the internal hardware of the host will watch which input port the response comes in on, and log that port for the software. Software can then map that input port to direct memory access/addressing engines in the host such that data streams can be steered to the appropriate application.

摘要： The present invention relates to a method and apparatus for directing causes of non-maskable interrupts. The apparatus determines whether a computer system is designed to handle an alternative interrupt such as a SCI interrupt. If the system is capable of handling alternative interrupts, forwarding circuitry forwards the causes of non-maskable interrupts to an alternative interrupt handler. If the system is not capable of handling alternative interrupts, the apparatus forwards the cause of non-maskable interrupts to a NMI handler.

摘要： Described within is a power management system for a computing platform that provides additional reductions in power consumption from that provided by only periodically putting the CPU or peripheral devices in low power non-operational states. In particular, the embodiment prevents the OS from generating an interrupt due to timer ticks while in a non-C0 state, until such time as a number of timer ticks have been gathered.

摘要： An apparatus communicates with an advanced switching (AS) fabric. The apparatus includes a transmit engine that generates a request packet for transmission to the AS fabric. The transmit engine associates a first transaction identifier with the request packet. A receive engine receives a reply packet in response to the request packet. The reply packet contains a second transaction identifier. The receive engine compares the first transaction identifier to the second transaction identifier. If the first transaction identifier matches the second transaction identifier, the receive engine decides to store data from the reply packet at an address associated with the first transaction identifier.

摘要： The present invention is a method and system to automatic loading program on a medium into memory for execution. In one embodiment, a mode word is configured. The insertion of the medium into a drive is detected based on the mode word. A program on the medium is started when insertion is detected. In another embodiment, a polling circuit in a chipset detects the insertion of the medium into the drive. A status bit is checked in response to an interrupt generated by the polling circuit. A flag in a memory is updated based on the status bit. A poll request by an operating system is responded.
