ABSTRACT:
A microprocessor is provided which detects dependencies among instructions. The microprocessor assigns each instruction to a processing element or elements which perform the operation specified by the instruction. Additionally, the microprocessor is configured to dynamically alter the interconnect between the processing elements such that dependent operations receive operands from the operations upon which they depend. In particular, an instruction which computes a result upon which another instruction depends is connected to provide the result to that instruction. Routing of data between processing elements is determined prior to the execution of the instructions. Using the dynamic reconfiguration of interconnections, the microprocessor executes instruction sequences more efficiently than a DSP which is optimized for another instruction sequence. Because the connections are reconfigurable, the microprocessor may be configured for the efficient execution of many different instruction sequences (as opposed to the limited number imposed by typical DSPs).
