Abstract

The execution model for mobile, dynamically-linked, object--oriented programs has evolved from fast interpretation to a mix of interpreted and dynamically compiled execution. The primary motivation for dynamic compilation is that compiled code executes significantly faster than interpreted code. However, dynamic compilation, which is performed while the application is running, introduces execution delay. In this paper we present two dynamic compilation techniques that enable high performance execution while reducing the effect of this compilation overhead. These techniques can be classified as: 1) decreasing the amount of compilation performed (Lazy Compilation), and 2) overlapping compilation with execution (Background Compilation). We first
