AIPW Summary: A system and method for performing convolution in vector processing. The method uses the parallel computing capability of a vector processing system and the distributed properties of the discrete-time convolution sum by performing convolution on portions of an overall data stream simultaneously. Partial solutions are obtained and superimposed to achieve an overall solution data stream. Basically, signal processing requires large amount of computing power to process a data stream in a serial manner, since it is a linear process. This invention breaks up the stream into smaller pieces and uses parallel processing to process several pieces simultaneously, thereby speeding up the overall process. (The actual solution gets deeper into the math involved, and is a bit on the “heavy reading” side of things. Feel free to peruse it yourself.)
