| Summary: | 碩士 === 國立交通大學 === 資訊科學與工程研究所 === 102 === JavaScript is a dynamic language that is widely supported in modern Web browsers.JavaScript programs are usually executed by a JavaScript engine, which is implemented using an interpreter or a just-in-time compiler. However, the dynamic aspects of interpretation and run-time compilation intrinsically limit the performance of JavaScript programs. In this paper, we propose a JavaScript compiler, called JSComp,that statically translates partial JavaScript programs into Native Client modules or asm.js programs for improving the execution performance and also a hybrid execution model (a combination of static compilation and dynamic interpretation) for JavaScript programs so as to take advantages of high-performance execution in the compilation model and dynamic code evaluation in the interpretation model. Our evaluations demonstrated that the proposed mechanisms were effective in improving the execution performance of JavaScript programs in the SunSpider benchmark suite by an average of 50%.
