    摘要: A transmitting device and a receiving device are coupled via a high-speed serial interface within a computer system. The transmitting device transmits a packet for a request transaction to a receiving device. The receiving device checks for error conditions. If an error condition exists and if the packet for the request transaction indicates that a completion is not expected by the transmitting device, an error message is delivered by the receiving device to the transmitting device.

    摘要: A requesting device and a completer device are coupled via a high-speed serial interface within a computer system. The requesting device transmits a packet for a request transaction to a completer device. The completer device checks for error conditions in the course of servicing the request. If an error condition is found then the completer device transmits a completion packet with a completion status of something other than successful. The completion packet includes a completer identification field. The requesting device records the completer identification value and indicates in a register that a completion packet has been received with a non-successful completion status.

    摘要: A point-to-point interconnection and communication architecture, protocol and related methods. System resources are dynamically shared based on contents of information received for transmission within the system. Virtual channels may be used for transmission of the information received for transmission over a general input/output (GIO) bus.

    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 of detecting synchronization errors during the transfer of data in which a transmitting agent sends to the receiving agent either: (a) data parity encoded with a data parity function when the transmitting agent encodes data in one or more clock signals, or (b) header parity encoded with a header parity function when the transmitting agent encodes header information in the one or more clock signals. A synchronization error condition is detected when the receiving agent either: (a) is configured to receive the data parity and actually receives the header parity, or (b) is configured to receive the header parity and actually receives the data parity.

    摘要: A bridge coupling a primary bus to two secondary buses. The bridge contains three interfaces, one for the primary bus and the other two for the two secondary buses. Control circuitry is included within the bridge to support the execution of a transaction initiated by a bus master upstream of the bridge to a target downstream of the bridge. The bridge also supports the execution of a transaction initiated by a bus master coupled to either one of the secondary buses to a target upstream of the bridge.
