Instruction set architecture impact on design space subsetting for configurable systems

摘要

A major challenge in design space subsetting is the time consumed in evaluating all of the design space configurations and selecting a subset of best/near-best configurations - those that adhere closely to design constraints. If an architect determines a subset for an instruction set architecture (ISA) that is historically coupled the system's domain, the evaluation process must be repeated if the architect is to consider an alternative ISA, wasting precious design time. In this paper, we compare different ISAs' best configuration subsets and investigate the possibility of selecting an ISA-independent subset that provides good domain constraint adherence regardless of the ISA.
