Synthesis of systolic arrays from single assignment algorithm

A systematic method of mapping algorithms from single assignment algorithms into systolic arrays is presented. The method is based on a space-time mapping technique of the index sets. We present a method of generation and selection of a valid transform dependency matrix that will yield an optimal or near optimal systolic array once it is mapped. The proposed method increases the visibility of the architecture in terms of processor delay and communication between processors at the algorithmic level, so that the designer is able to select a desired array at early stages of the design. An example of the proposed method is given.<>
