Abstract:12 -Heterogenous datapaths maximize the utilization of functional units (FUs) by customizing their widths individually through fragmentation of wide operands. In comparison, slices in large functional units in a homogenous datapath could be spending many cycles not performing actual useful work. Various fragmentation techniques demonstrated benefits in minimizing the total functional unit area. Upon a closer look at fragmentation techniques, we observe that the area savings achieved by heterogenous datapaths c… Show more
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.
