Optimisations Techniques for the Automatic ISA Customisation Algorithm

摘要

This article introduces some improvements to the already proposed custom instruction candidates selection for the automatic ISA customisation problem targeting reconfigurable processors. It introduces new opportunities to prune the search space, and a technique based on dynamic programming to check the independence between groups. The proposed new algorithm yields one order less measured number of convexity checks than the related work for the same inputs and outputs.
