  Abstract

Visual media(image, graphic, and video) processing poses challenge from several perspectives, specifically from the point of view of real-time implementation and scalability. There have been several approaches to obtain speedups to meet the computing demands in multimedia processing ranging from media processors to special purpose implementations. A variety of parallel processing strategies are adopted in these implementations in order to achieve the required speedups. We have investigated a parallel processing system for improving the processing speed of visual media related applications. The parallel processing system we proposed is similar to a pipelined single instruction multiple data(SIMD) architecture that consists of processing elements(PEs) and a multi-access memory system(MAMS). The multi-access memory system is made up of m memory modules and a memory controller to perform parallel memory access with a variety of combinations of 1×pq, pq×l, and p×q subarray, which improves both cost and complexity of control. Facial recognition, Phong shading, and automatic segmentation of moving object in image sequences are some that have been applied to the parallel processing system and resulted in faithful processing speed. ll1is paper describes the parallel processing systems for the speedup and its utilization to three time-consuming applications.
