Residue number system in the VLSI architecture for image processing algorithms ? A review

Improving the computational speed in embedded image processing systems has been of great technical significance. The time elapsed for inter-modular carry propagation in binary arithmetic adversely affect the computational speed and power efficiency of such systems. Different from binary arithmetic, the residue number system has the capability of modular arithmetic and it is devoid of the inter-modular carry propagation. This article reviews image processing applications making use of the residue number system based arithmetic.
