Abstract

This paper examines several parallel image processing architectures designed for convolution filtering and solving least-square problems. Six papers on convolution are examined three describe linear systolic array designs and three describe special-purpose implementations. Four papers on median filter are examined. The algorithms used are all slightly different but the architectures are very different. Finally arrays that solve the least-squares problem using the QR decomposition method are examined. The criteria used to analyze the architectures are the intended environment the characteristics of the algorithms and the requirements of the host the cell and the array. 1.
