Abstract:

The research sponsored by this grant is focused on the development of a theoretical and technological basis for designing efficient systolic arrays for digital-signal processing algorithms. The major contributions of the research are the following Data reduction techniques via the utilization of algorithm properties Conversion of sequential input signal into input blocks by means of a spiral systolic mesh that is suitable for parallel processing and that is flexible for enabling various array dimensions Devising a hybrid of SA and data-flow approach, making data streams independent of computations executed in each processor, thus reducing waiting time. The communication PE protocols resolve the data-flow conflicts created by the merging of the spiral and asynchronous systolic array architecture.
