Efficient direct analog-to-residue conversion schemes

Residue Number System (RNS) based processors offer several advantages in terms of speed and power. The embedded parallel processing property of RNS with the absence of carry propagation makes it very suitable for long word addition and multiplication intensive algorithms. The conversion from real world analog signals to residue and vice versa plays a crucial role in the overall performance of the system. In this paper, we present two architectures for direct conversion from analog-to-residue. The performance of the proposed schemes is analyzed.
