CPR: A Conguration Proling Tool

In this paper we describe a Conguration PRoling tool (CPR) and show how it can be used to aid compiler designers, FPGA architects and in the con-struction of a macro-generator libraries. CPR uses subgraph matching to identify the parts of an ap-plication which are most important to achieve high performance. Using CPR as a guide we implemented a few macros for a macro-generator library, which yielded signicant improvement in both the quality of congurations and speed of compilation.
