Java processor

Java processor

A Java processor is the implementation of the Java Virtual Machine (JVM) in hardware.In other words the bytecodes that make up the instruction set of the abstract machine become the instruction set of a concrete machine.

Implementations

Up to now only a few Java processors are available:

*picoJava was the first attempt by Sun Microsystems to build a Java processor
* [http://www.ajile.com/ aJ100] from aJile. Available on boards from [http://jstamp.systronix.com/ Systronix]
* [http://www.imsystech.com/ Cjip] from Imsys Technologies
* [http://ipr.ira.uka.de/komodo/komodoEng.html Komodo] is a multithreaded Java microcontroller for research on real-time scheduling
* [http://www.inf.ufrgs.br/~lse/ FemtoJava] is a research project to build an application specific Java processor
