    摘要: Provided are a method, system, and article of manufacture for providing data integrity for data streams. Input data streams are received. A parity data stream is generated by computing parity data from the input data streams, wherein the parity data stream comprises data blocks. Data integrity fields are computed for the data blocks, wherein a data integrity field is used to ensure the integrity of a data block for which the data integrity field is computed. The computed data integrity fields are added to the data blocks to generate an output stream.

    摘要: A method and apparatus for interfacing a device which is compliant to a first bus protocol to a second bus having a second protocol and for providing virtual functions through an intelligent bridge. The interface apparatus is coupled to the first bus and the second bus. The interface device detects a configuration cycle on the second bus and translates the configuration cycle into a corresponding cycle in a format understandable by the first bus. The bus cycle is executed on the first bus. A local processor is interrupted by the interface apparatus. A verification and correction program is executed by the local processor to restore configuration header values if the executed bus cycle violated the protocol of the second bus. The interface apparatus insures that requests for access to the first bus are blocked during the execution of the verification and correction program.

    摘要: A multi-functional device that integrates a high performance processor into a PCI to PCI bus bridge. The invention consolidates a high performance processor, a PCI to PCI bus bridge, PCI bus-processor address translation unit, direct memory acces's (DMA) controller, memory controller, secondary PCI bus arbitration unit, inter-integrated circuit (I.sup.2 C) bus interface unit, advanced programmable interrupt (APIC) bus interface unit, and a messaging unit into a single system which utilizes a local memory. The PCI bus is an industry standard high performance, low latency system bus. The PCI to PCI bridge provides a connection path between two independent 32-bit PCI buses and provides the ability to overcome PCI electrical loading limits. The addition of the local processor brings intelligence to the PCI bus bridge.
