Design of a reconfigurable dsp processor using rns for mobile computing and embedded systems

Abstract

In the recent days, the exponential growth in functionality of mobile devices leads the manufacturers to develop more and more sophisticated microprocessors and micro controllers. The power requirements of the microproces sors are increasing day by day along with the processing speed and chip area. So, rather than traditional number systems, Residue Number System (RNS) is becoming attractive for their capabilities for performing addition and multiplication operation efficiently. In this paper, based on the formulation of the Chinese remainder theorem and RNS, a guideline for a Reconfigurable DSP Processor is proposed that can process some predefined functions. As RNS minimizes the carry propagation, the scheme can be implemented in Mobile and Wireless Computing and oth er fields where high speed computations are required with limited resources.
