Concluding Remarks

Our current work is aimed at integrating these optimizations into the PLTO binary rewriting tool [19], and then using the tool to test further the effectiveness of the approach. A number of potential targets have been identified ranging from utility programs like gzip and pzip, to web servers and database applications. We also intend to explore the applicability of these techniques for small mobile devices. Independent of the savings in CPU cycles, we believe our approach will yield significant energy savings in this context, greater in fact than what the reduction in CPU cycles would imply.
