摘要： The invention comprises an apparatus and method of prefetching from a memory device having interleaved channels. The chipset prefetcher comprises a stride detector to detect a stride in a stream, a prefetch injector to insert prefetches onto the memory device, a channel mapper to map the prefetches to each channel of the memory device, a scheduler to schedule the prefetches onto the memory device in a DRAM-state aware manner, a throttling heuristic to scale the number of prefetches, and a prefetch data buffer to store prefetch data. The method of prefetching comprises tracking the state of streams, detecting a stride on one of the streams, selecting the stream with the stride for prefetch injection, enqueueing prefetches from the selected stream, mapping the prefetches to each of the interleaved channels, injecting the prefetches from the selected stream into each of the interleaved channels, and scheduling the prefetches onto the memory device in a DRAM-state aware manner.

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 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.
