摘要： A data processing architecture comprising: a parallel array of processing elements arranged in a single instruction multiple data processing array; a hardware accelerator unit operable to receive, in series, processing requests from the processing elements and to return processing results to respective processing elements when those processing results are available; and an input/output system which is operable to transfer respective processing requests from the processing elements to the hardware accelerator, and to return processing results to the processing elements concerned, wherein the processing elements are operable to process the returned processing results when all such results are returned, or after a predetermined time period.

摘要： A look up engine 200 comprising a storage means 212a, 212b for storing a plurality of entries, each entry comprising a value and an associated key value, such that, in operation, a look up is carried out by outputing a value which is associated with the stored key value which matches an input key value. The look up engine 200 comprises a plurality of look up state machines 206a, 206b, 206c, 206d connected in parallel to enable multiple look ups to be carried out concurrently. Each entry comprises an associated skip value, if the skipped bits of the input key value and the associated skip value mismatches, an error message is output to indicate lookup failure. The entries may be stored in a trie format which is constructed by identifying overlapping ranges between the plurality of entries; splitting the identified overlapping ranges; storing the plurality of entries within a trie structure.
