Implementing fast JVM interpreters using Java itself
2007
Proceedings of the 5th international symposium on Principles and practice of programming in Java - PPPJ '07
Preserved Fulltext
We have implemented an alternative approach, in which the JVM interpreter itself is built in Java, and runs atop a host JVM execution environment. ...
If a mixed-mode VM environment is desired, a generic JVM interpreter can subsequently be created using Java itself. ...
Implementing the JVM interpreter in Java itself has a number of advantages over the traditional C or C++ based implementation approach. ...

Efficient techniques to implement Java virtual machines that are suitable for use in resource constrained environments are thus needed. ...
We compare our implementation with two well known Java processors, JOP and Sun's picoJava-II, on the same technology. ...

Although the C-based interpreter of Python is reasonably fast, implementations on the CLI or the JVM platforms offers some advantages in terms of robustness and interoperability. ...
Unfortunately, because the CLI and JVM are primarily designed to execute statically typed, object-oriented languages, most dynamic language implementations cannot use the native bytecodes for common operations ...
Acknowledgments The work presented in this paper fits into the PyPy project; the authors mainly worked on ootype and on the back-ends for CLI and JVM, and all the rest belongs to the PyPy team [30] , ...

For this purpose, we first implemented a compact Java Virtual Machine with a Just-In-Time compiler on the Intel IA32 instruction set architecture at the user space. ...
An alternative approach is to provide a run-time system within the operating system itself that can execute user kernel extensions. ...
While implementations of the JVM have been used for kernel extensions, they have tended to rely on bytecode interpretation. ...

As a proof of concept, we have implemented hardware objects in three quite different JVMs: in the Java processor JOP, the JIT compiler CACAO, and in the interpreting embedded JVM SimpleRTJ. ...
When running the JVM on bare metal, we need access to I/O devices from Java; therefore we investigate a safe and efficient mechanism to represent I/O devices as first class Java objects, where device registers ...
