Fast Base-10 Multiplication Using XS-3 and ODDS BCD codes
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
We present the algorithm and architecture of a BCD parallel multiplier that exploits some properties of two different redundant BCD codes to speed up its computation: the redundant BCD excess-3 code (XS-3), and the overloaded BCD representation (ODDS). In addition, new techniques are developed to reduce significantly the latency and area of previous representative high performance implementations. Partial products are generated in parallel using a signed-digit base-10 recoding of the BCD multiplier with the digit set [-5,5], and a set of positive multiplicand multiples (0X, 1X, 2X, 3X, 4X, 5X) coded in XS-3.
