Abstract

We present a design of high-radix digit-slices for the implementation of on-line multiply-add operator (OMA). Our evaluation of performance and cost shows that speedups above 1.5 can be obtained with respect to radix 2 at reasonable increase in cost. The design and evaluation are based on the Xilinx FPGAs. We also discuss the use of OMAs modules in solving linear recurrences.
