One of the popular methods of asynchronous logic implementation is based on so called Delay-Insensitive-Minterm-System (DIMS), where a sum-of-minterms (SOM) function is given and each minterm is represented using a state-holding (C-) element. However, such implementation is rather expensive since minterm minimization is not allowed. In the paper, structure called factorized DIMS is proposed. It is shown that under realistic delay limitation, instead of SOM, strong indication can be ensured for the sum of mutually orthogonal product terms resolved into factorized form. It reduces significant implementation complexity.
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.
