I am interested in the JVM since early 1996, when I joined
MATHEMA Software GmbH as a software developer (and
later course instructor). All my early research about the JVM originated at MATHEMA, and
I am still very thankful for all the inspiration that I got there.
The Java Virtual Machine
Since its introduction in late 1995 the Java programming language has literally
attracted millions of software developers, and today Java is one of the most
commonly used software platforms.
The Java Virtual Machine (JVM) is the heart of every Java environment. The term "Java
Virtual Machine" refers to the specification of an abstract Java processor as well as
to its concrete implementation in software.
In spring 2000 I changed to PTSC (formerly named
Patriot Scientific Corporation), to work on the JVM implementation for their
IGNITE microprocessor series.
Below is a collection of my articles and presentations related to the JVM:
Design and Implementation of a Java Bytecode
Recompiler for ARM RISC Processors
This paper describes how Java bytecode can be efficiently translated to
ARM machine code.

The Inner Workings of the Java Virtual Machine
This presentation is a general introduction to the internals of the JVM. It gives an
overview of the structure of the JVM and explains the function of its individual
components. The slides were made for a presentation at the December 2002 meeting of
the San Diego Java User's Group (SDJUG).
