RECONFIGURABLE PROCESSOR ARRAY EXPLOITING ILP AND TLP

摘要

A processing system according to the invention comprises a plurality of processing elements, and the plurality of processing elements comprises a first set of processing elements and at least a second set of processing elements. Each processing element of the first set comprises a register file and at least one instruction issue slot, and the instruction issue slot comprises at least one functional unit. This type of processing element is dedicated for executing a thread with no or a very low degree of instruction-level parallelism. Each processing element of the second set comprises a register file and a plurality of instruction issue slots, and each instruction issue slot comprising at least one functional unit. This type of processing element is dedicated for executing a thread with a large degree of instruction-level parallelism. All processing elements are arranged to execute instructions under a common thread of control. The processing system further comprises communication means arranged for communication across the processing elements. In this way the processing system is capable of exploiting both thread-level parallelism and instruction-level parallelism in an application, or a combination thereof.
