In the push for ever increasing performance out of processor architectures, there is a need to expand bqond the limitations of existing scalar approaches. Superscalar architectures provide one such means. By dynamically executing more than one instruction per clock cycle, superscalar architectures can improve performance without relying solely on technology improvements for these gains. lhis paper examines a new technique for superscalar control implementation, called the schedule table. i'he schedule table facilitates dependency checking, out of order instruction issue, out of order execution, branch prediction, speculative execution, precise interrupts, and fmt and eficient misprediction recovery.
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.
