Memory Requirements of Java Bytecode Verification on Limited Devices
2005
Electronical Notes in Theoretical Computer Science
Preserved Fulltext
Limited devices, like Java smart cards, lack the necessary amount of memory to verify the type-safety of Java bytecode on their own. ...
In this paper, we extend this approach to real world Java software and develop a precise model of the memory requirements on the device. ...
Conclusion Rose's proof carrying code approach for bytecode verification on limited devices has served as the starting point of our research. ...

However, native code is much bigger than Java bytecode, which severely limits or even forbids these practices for devices with memory constraints. ...
Results show memory footprints for native code that are up to 70% smaller than the non-optimized version, and sometimes as low than 115% the size of the Java bytecode when compiled for ARM thumb. ...
Acknowledgments The authors would like to thank Jean-Louis Lanet for kindly providing us with the JML-annotated sources of the banking, scheduler and tcpip programs evaluated in this paper. ...

In this paper, we propose EJVM (Economic Java Virtual Machine), an economic way to run Java programs on network-enabled and resource-limited embedded devices. ...
In addition, we use two novel techniques to reduce the client-side memory footprints: server-side class representation conversion and on-demand bytecode loading. ...
Unfortunately, it is not easy to apply Java technology to resource-limited embedded devices due to the large resource requirements of Java platforms. ...
