摘要： A multiple node computer system includes processor nodes, memory nodes, and input/output nodes interconnected on a pended bus. The system includes a lockout indicator which is set upon receipt of a locked response message by a processor node from a memory node in response to an interlock read command. The processors include a lockout check circuit responsive to the condition of the lockout indicator and will restrict generation of additional interlock read commands according to a predetermined access gating criterion until the lockout indicator is reset. In this manner, processor nodes of the system are assured equitable access to a memory node.

摘要： A prediction logic device operating in conjunction with a vector processor to predict, before the completion of the translation of the virtual addresses of all of the data elements of a vector, the valid performance of all virtual-address to physical-address translations for the data elements of the vector. The prediction logic device asserts an MMOK signal to a scalar processor when it becomes known that no memory management fault and/or translation buffer miss will occur such that the scalar processor can resume vector instruction issue to the vector processor at the earliest possible time.

摘要： Apparatus and method for servicing interrupt requests on a pended bus. An interrupt servicing node provides interrupt acknowledge messages including destination data specifying a particular interrupting node at times when the interrupt servicing node is ready to service an interrupt request message. The interrupt servicing node includes storage for specifying the identity of a particular interrupting node and for indicating that an interrupt request is pending from a particular interrupting node. An interrupting node provides to the pended bus an interrupt request message including ID data for identifying the interrupting node as the source of an interrupt request. The interrupting node detects whether an interrupt acknowledge message on the bus includes destination data specifying that interrupting node.

摘要： A memory node in a computer system having multiple processors interconnected by a pended bus provides exclusive read-modify-write operations employing multiple lock bits. A processor generates an interlock read command which is transmitted as a transfer over the pended bus to the memory node. Acknowledge confirmations are transmitted by the memory back to the processor two bus cycles after each bus cycle of the processor transfer. The processor transfer, including an interlock read command, is stored in a input queue in memory and processed in turn by the memory. A first interlock read command to a specified memory location causes a lock bit to be set for that location and a first type of response message including the contents of the specified location to be generated by the memory and stored in an output queue. The memory obtains access to the pended bus through an arbitration process and transmits a response message including the contents of the memory location specified in the interlock read command at an unspecified time after initiation of the interlock read command. A subsequent interlock read command from the processor to the same memory location will result in a denial of access to the specified location and in the generation of a second type of response message by the memory which indicates that the specified location is locked.

摘要： A load/store pipeline in a computer processor for loading data to registers and storing data from the registers has a cache memory within the pipeline for storing data. The pipeline includes buffers which support multiple outstanding read request misses. Data from out of the pipeline is obtained independently of the operation of the pipeline, this data corresponding to the request misses. The cache memory can then be filled with the requested for data. The provision of a cache memory within the pipeline, and the buffers for supporting the cache memory, speed up loading operations for the computer processor.
