Abstract. Customizable processors augmented with application-specific Instruction Set Extensions (ISEs) have begun to gain traction in recent years. The most effective ISEs include Architecturally Visible Storage (AVS), compiler-controlled memories accessible exclusively to the ISEs. Unfortunately, the usage of AVS memories creates a coherence problem with the data cache. A multiprocessor coherence protocol can solve the problem, however, this is an expensive solution when applied in a uniprocessor context. I…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
