摘要： Responsive to a data lookup in a buffer triggered for a search string, a processor searches for a selection of pairs from among multiple pairs of a hash table read from at least one address hash of the search string and matching at least one data hash of the search string, each row of the hash table assigned to a separate address hash, each of the pairs comprising a pointer to a location in the buffer and a tag with a previous data hash of a previously buffered string in the buffer. The processor identifies, from among the selection of pairs, at least one separate location in the buffer most frequently pointed to by two or more pointers within the selection of pairs. The processor, responsive to at least one read string from the buffer at the at least one separate location matching at least a substring of the search string, outputs the at least one separate location as the response to the data lookup.

摘要： Multiple clients may attempt to utilize a coprocessor engine within a coprocessor simultaneously. However, each engine may accomplish the particular function for which it is designed for one client at a time. Therefore, to transition from performing coprocessor engine operations between clients, the coprocessor engine may be suspended from performing operations for a first client so that it may begin performing operations for a second client. Prior to such transition, the coprocessor engine saves metadata about its operation state at the time of the suspend. At a subsequent time, when operations for the first client are to resume, the operating state of the coprocessor engine is determined utilizing the metadata and operations for the first client resume.

摘要： A method for sorting data in an array processor. Each of a first tier of processing elements in the array processor receives data inputs from a load streaming unit. Each of the first tier processing elements compares input data portions received from the load streaming unit, wherein the input data portions are stored for processing in respective queues. The first tier processing elements select one of the input data portions to be an output data portion based on the comparison, and in response to the selection, remove a corresponding queue entry and request next input data from the load streaming unit. Each of the first tier processing elements further provides the output data portion as an input data portion to a second tier processing element that generates output data based on a comparison of output data received from at least two first tier processing elements.

摘要： An array processor includes a managing element having a load streaming unit coupled to multiple processing elements. The load streaming unit provides input data portions to each of a first subset of processing elements and receives output data from each of a second subset of the processing elements based on a comparatively sorted combination of the input data portions. Each processing element is configurable by the managing element to compare input data portions received from the load streaming unit or two or more of the other processing elements. Each processing unit can further select an input data portion to be output data based on the comparison, and in response to selecting the input data portion, remove a queue entry corresponding to the selected input data portion. Each processing element can provide the selected output data portion to the managing element or as an input to one of the processing elements.

摘要： Aspects include copying a plurality of input data into a buffer of a processor configured to perform speculatively executing pipelined streaming of the input data. A bit counter maintains a difference in a number of input bits from the input data entering a pipeline of the processor and a number of the input bits consumed in the pipeline. The pipeline is flushed based on detecting an error. A portion of the input data is recirculated from the buffer into the pipeline based on a value of the bit counter.
