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
- aJ100, aJ102 and aJ200 from aJile. Available on boards from Systronix
- Cjip from Imsys Technologies. Available on boards and with wireless radios from AVIDwireless[1]
- Komodo is a multithreaded Java microcontroller for research on real-time scheduling
- FemtoJava is a research project to build an application specific Java processor
- ARM926EJ-S is an ARM processor able to run java bytecode
