Abstract

In applications, such as high quality audio, that need more than 16 bits of precision, the processing of signals on a 16-bit DSP requires double precision computation and is hence time consuming. Since in residue number system (RNS), the high precision data is decomposed to a lower precision for its processing, in this paper, we propose RNS for increasing the performance of such applications implemented on a single processor. We apply multirate architectures and also suggest some architectural extensions to the processor to further enhance the performance. The results show that performance improvement of more than 57% can be achieved with these implementations. We also show that the power dissipation can be significantly reduced with such implementations.
