Efficient image processing application using residue number system

This paper presents an implementation of a digital image processing application on the field programmable gate array (FPGA) using the residue number system (RNS). This application includes applying a number of filters in spatial domain, such as sharpen, edge detection and enhancing on a gray-scale image. All the processing is done using the RNS instead of the binary number system. The proposed work proves that using the RNS results in faster and power-reduced image filtering applications. Moreover, this paper highlights the negative effect of using improper moduli sets in RNS based image-processing applications.
