Off-the-shelf soft core processors are becoming increasingly popular in embedded systems design today as they provide for application specific customization, in particular through instruction subsetting. However, choosing the right processor configuration remains a challenge as the search space becomes prohibitively large when the configurable options increase. In this paper, the authors propose a framework to rapidly explore the processor configuration design space for a given application. Unlike existing approaches that require time-consuming synthesis process, the proposed method relies only on a single-pass output of the LLVM compiler infrastructure.
