Dynamic binary translation (DBT) translates binary code from one instruction set architecture (ISA) to another (same or different) ISA at runtime, which makes it very useful in many applications such as system virtualization, whole program analysis, system debugging, and system security. Many techniques have been proposed to improve the efficiency of DBT systems for long-running and loop-intensive applications. However, for applications with short running time or long-running but with few hot code regions such as JavaScript and C# applications in web services, such techniques have difficulty in amortizing the overhead incurred during binary translation. To reduce the translation overhead for such applications, we propose a general persistent code caching framework, which allows the reuse of translated binary code across different executions for the same or different applications. Compared to existing approaches, the proposed approach can seamlessly handle even dynamically generated code, which is very popular in script applications today. A prototype of the proposed framework has been implemented in an existing retargetable DBT system. Experimental results on a list of applications, including C/C++ and JavaScript, demonstrate that it can achieve 76.4% performance improvement on average compared to the original DBT system without helper threads for dynamic binary translation, and 9% performance improvement on average over the same DBT system with helper threads when code reuse is combined with help threads.
Pen-Chung Yew is a professor in the Department of Computer Science and Engineering, University of Minnesota (UMN) at Twin Cities. He served as the Head of the department and the holder of the William-Norris Land-Grant Chair Professor between 2000 and 2005. Before joining UMN, he was on the faculty of the Department of Electrical and Computer Engineering, and was an Associate Director of the Center for Supercomputing Research and Development (CSRD) at the University of Illinois at Urbana-Champaign (UIUC). From 1991 to 1992, he served as the Program Director of the Microelectronic Systems Architecture Program in the Division of Microelectronic Information Processing Systems at the National Science Foundation (NSF), Washington, D.C.
Pen-Chung Yew is an IEEE Fellow. He served as the Editor-in-Chief of the IEEE Transactions on Parallel and Distributed Systems (TPDS) between 2000 and 2005. He also served as the program chair or general chair of several major conferences in the past 5 years that include:  2014 Int’l Symposium on Computer Architecture (ISCA), 2012 Int’l Conference on Parallel Architectures and Compiler Techniques (PACT), 2011 ACM SIGPLAN 16th Annual Symposium on Principles and Practice of Parallel Programming (Ppopp), and 2010 39th Int'l Conference on Parallel Processing (ICPP). He also served on the program committee of many major conferences.
