Image processing plays a vital role in many applications like automation, visual inspection. Thus the Image processing system should meet the real time demand. Many factors like salt and pepper noise will affect the image processing system. This paper introduces the double parallel architecture using sort optimization algorithm to accelerate the median filter and edge detection. The double parallel architecture is divided in to two parts image level parallel and operation level parallel. The
