    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: A computer system having a responsive low-power mode and a full-power mode of operation. The computer system includes a power consumption controller, a processor and a communication device. The power consumption controller generates an interrupt signal in response to a low power event or a fully operational event. The power consumption controller also generates a clock control signal. The clock control signal is deasserted during the full-power mode of operation and alternatively asserted for a first duration and deasserted for a second duration during the low-power mode of operation. In response to an asserted clock control signal, the processor suppresses the internal clock signal to at least one functional block within the processor and in response to a deasserted clock control signal, the processor transmits the internal clock signal to at least one functional block within the processor. By transmitting the internal clock signal to at least one functional block within the processor during the low-power mode of operation, the processor may respond to communication signals from a communication device during the low-power mode of operation.

    摘要: An address translation apparatus and method that can convert a limited-range memory address from a peripheral device to an expanded-range memory address on the fly. The invention can expand the limited address capability of a peripheral bus, such as a PCI bus with a 4 GB address range, to a much larger address capability, such as a 64 GB address range. This conversion can be performed on the fly by hardware, so that no appreciable delay in transfer time is created. The conversion can be performed by adding features to a conventional graphics controller interface, thus minimizing the impact on circuit complexity and system cost.

    摘要: A circuit for controlling interrupt request signal transmission in a computer system. An input receives an interrupt request from an external component. First circuitry coupled to the input generates a signal in response to the interrupt request from the external component. The signal causes a processor to switch to fully operational mode. Second circuitry coupled to the input generates an interrupt request signal to the processor in response to the interrupt request from the external component. A signal processing circuit coupled to the second circuitry suppresses transmission of the interrupt request signal to the processor until the signal is transmitted to the processor.

    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: 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.
