UNIFIED APPROACH TO DESIGNING PARALLEL WINOGRAD ALGORITHMS

Abstract

Although the recurrence equation for the Winograd algorithm is uniform, no unified approach has been proposed to design parallel Winograd algorithms. In the paper the authors propose a unified approach to designing parallel Winograd algorithms. Using this approach, several parallel algorithms are designed. These algorithms are executed on regular arrays including conventional systolic arrays and nonplanar regular arrays. A comparison of their performance is given.
