Tradeoff analysis of integer multiplier circuits implemented in FPGAs

Integer multiplication is a necessary operation for performing many tasks relevant to multimedia and telecommunications processes. Here, we discuss the results of an investigation into the effectiveness of automated synthesis tools as related to a sample of modern Programmable Logic Devices (PLDs). Although it is generally accepted that superior results in terms of required area and circuit delay can generally be obtained through manual implementation of such circuits, the exclusive use of automated synthesis tools based upon an original specification in terms of a Hardware Description Language (HDL) is presented here. The results of several different approaches to multiplier architectures are presented
