    摘要: A mechanism is provided in a data processing system for enhancing wiring structure for a cache supporting an auxiliary data output. The mechanism splits the data cache into a first data portion and a second data portion. The first data portion provides a first set of data elements and the second data portion provides a second set of data elements. The mechanism connects a first data path to provide the first set of data elements to a primary output and connects a second data path to provide the second set of data elements to the primary output. The mechanism feeds the first data path back into the second data path and feeds the second data path back into the first data path. The mechanism connects a secondary output to the second data path.

    摘要: An InfiniBand™ Channel Adapter encrypts or decrypts user data on-the-fly. The user data is read from system memory and encrypted in by the Channel Adapter before sending it to a network. Similarly received data is decrypted on the fly before storing it in system memory. The encryption/decryption keys are preferably stored in a Queue Pair Context storage area of system memory as Public key for sending data and Private key for receiving data.

    摘要: A memory interface between the storage controller and memory card of an S/390 system uses the S/390 Storage Protect (SP) Key as an indication or protocol of storage command acceptance by the memory card. When the SP key is returned, then the command is deemed to be accepted by the memory card and the key will be used by the processor for its storage validation in accordance with the S/390 architecture. In the event that the memory card detected an error associated with the command, it will then return an error response code via a memory status bus. The memory status bus is multiplexed to service the existing architected requirement as well as an indicator of handshaking between the memory controller and the memory card.

    摘要: The present invention generally relates to digital network communication, and in particular to a method and system for processing data according to the InfiniBand™ (IB) Protocol with reduced latency and chip costs in an InfiniBand™ type computer system. ID information in a packet header is obtained before the body of the packet has completely arrived at a receiving Channel adapter. The ID information is used to obtain work Queue Pair Context (QPC) and when needed an associated Work Queue Element (WQE), for operating on the data content of the packet being received.
