A new RNS to mixed-radix number converter using modulo (2/sup p/ - 1) signed-digit arithmetic
Shugang Wei, Kasumi Shimizu · 2005
A hardware algorithm converting the numbers in a residue number system (RNS) to that in a mixed-radix number system by using signed-digit (SD) arithmetic is presented. In each residue digit of the RNS, integers m/sub i/ = (2/sup Pi/ - 1) are used as the moduli and the modulo m addition and multiplication can be performed by an end-around-carry SD adder and a binary modulo m SD adder tree, respectively. Thus a high speed converter can be designed by using the proposed modulo m SD adders and multipliers.
