主 题:image processing array processor window operation systolic array
摘 要:In this paper;we present a novel architecture named as Window-MSPA architecture which targets to window operations in image processing. We have previously developed a Memory Sharing Processor Array (MSPA) for fast array processing with regular iterative algorithms. Window-MSPA tries to optimize the data I/O ports and the number of processing elements so as to reduce hardware cost. The input scheme of image data is restricted to row by row input which simplifies the I/O architecture. Under this practical I/O restriction, the fastest processings are achieved. In this paper, we present the general Window-MSPA design methodology for wide variety of applications.,its an practical application, we have already reported the design of MP@HL MPEG2 Motion Estimator LS1[13]. Design formulas for Window-MSPA architecture are given for various size of window: operations in image processing. Thus, the derived architecture is flexible enough to satisfy user s requirement for either area or speed.
