In this paper, we propose a systematic pipelining method for a linear system to minimize power and maximize throughput, given a constraint on the number of pipeline stages and a set of resource constraints. The method first retimes operations such that as many operations as possible take common operands as their inputs, and then performs the operand sharing based on the list scheduling. Experimental results show that the proposed approach reduces the power consumption of the functional units by up to more than 20%, compared to the state-of-the-art pipelining and operand sharing techniques.
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.
