Automatic Memory Management on IOS Devices for Cross Compiled Java Applications

Professors Arno Puder and Hui Yang
XMLVM allows developers to write Java programs that use the Apple iOS API and then cross-compile them to native Objective-C programs. To execute these programs on iOS devices the Java Virtual Machine's (JVM) memory managed model must be supported. This project describes two separate ways in which to achieve this goal. Â First, an algorithm which analyzes JVM instructions and automatically inserts code to reference count Java objects to allow for memory management. Â Second, the Boehm garbage collector is embedded into the iOS application to replace the JVM's garbage collector. Â Reference counting and garbage collection are explained, compared, and contrasted within the context of XMLVM. The JVM instruction-based reference counting algorithm is described.
