Research Summary

Software dynamic translation (SDT) is a technology that permits the modification of an executing program's instructions. In recent years, SDT has received increased attention, from both industry and academia, as a feasible and effective approach to solving a variety of significant problems. Despite this increased attention, the task of initiating a new project in software dynamic translation remains a difficult one. To address this concern, and in particular, to promote the adoption of SDT technology into an even wider range of applications, we have implemented Strata, a cross-platform infrastructure for building software dynamic translators.
