When a Boolean function is transformed b y exclusive-OR with a suitably selected transform function, the new functaon is often synthesized wzth significantly reduced hardware. The transform function is separately synthesized and the oragznal functzon is recovered as an exclusive-OR of the two functaons. We select the transform to reduce the number of cubes in the function to be Synthesized. The function is represented as a Shannon expansion about selected varaables. A transform functaon zs constructed such that a selected set of cofactors is coniplemented to minimize the overall number of cubes. Examples of single-output functions show an aeerage area reduction of 19%. For a multiple-output function, transformations can be customazed for each output.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
