    摘要: A system is described for prefetching data from a main memory before the data is requested by a processor. The system includes a prefetch buffer having a number of entries to store prefetch reads. Each entry in the prefetch buffer includes a storage area designated for data and address. The system also includes a number of state machines, each state machine to track data phase for each entry in the prefetch buffer. A read request controller is coupled to the prefetch buffer and is configured to receive a read request from the processor or I/O devices and controls dispatching of prefetch requests to a main memory.

    摘要: For isochronous data steams processed by a computer system, for example high definition audio streams, embodiments keep track of the free space available in the input and output buffers for the data streams. The available free space in the buffers determines whether various low power entry and exit thresholds are met or not. If all low power entry thresholds are met, then various circuits such as clocks, phase locked loops, and direct media interface links, may be put into a low power state, and the data stream controller enters an idle window so that memory requests are not serviced. During this time, system DRAM may begin refresh. Once the low power state has been entered into, if any exit threshold is met, then the low power state is ended. Other embodiments are described and claimed.

    摘要: A method to deterministically shut down memory devices in response to a system warm reset has been disclosed. One embodiment of the method includes causing a first type of reset in a number of memory devices in a system in response to a second type of reset in the system being initiated if the memory devices are not initialized and enabling a deterministic shutdown mode in a memory controller, which is coupled to the memory devices, after the memory devices have been initialized. Other embodiments are described and claimed.

    摘要: A combination of techniques to prevent deadlocks and livelocks in a computer system having a dispatcher and multiple downstream command queues. In one embodiment, a broadcast transaction that requires simultaneously available space in all the affected downstream command queues becomes a delayed transaction, so that the command queues are reserved and other transactions are retried until the broadcast transaction is completed. In another embodiment, a bail-out timer is used to defer a transaction if the transaction does not complete within a predetermined time. In yet another embodiment, a locked transaction that potentially addresses memory space controlled by a programmable attribute map is handled as a delayed transaction if there is less than a predetermined amount of downstream buffer space available for the transaction.

    摘要: A method and apparatus for delivering APIC interrupts to a processor, and between processors, as FSB transactions. Interrupts and hardware signals, generated by a PCI device, are converted into an upstream memory write interrupt and further converted into an FSB interrupt transaction, received by a processor. Interrupts marked as lowest priority re-directable are redirected based on task priority information. Support for XTPR transactions to update XTPR registers is provided. Preferred ordering of XTPR update transactions and interrupts to be redirected is provided.

    摘要: Machine-readable media, methods, and apparatus are described to stream data between a codec and a buffer in system memory and to maintain a value in system memory that is indicative of a current position in the buffer. In some embodiments, an audio controller streams the data across an isochronous channel having relaxed ordering rules to the buffer in the system memory and updates the value indicative of current position via a write across the isochronous channel to the system memory.
