AVR32
The AVR32 Java Virtual Machine software loads and controls the execution of the Java classes.
The bytecodes are executed in hardware, except for some instructions, for example the instruc-
tions that create or manipulate objects. These are trapped and executed in software within the
Java Virtual Machine.

boots in AVR32 (RISC) state and it executes applications as a normal RISC processor. To
invoke a Java program, the Java Virtual Machine is called like any other application. The Java
Virtual Machine will execute an init routine followed by a class loader that parses the class and
initializes all registers necessary to start executing the Java program. The last instruction in the
