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
aJ102 and aJ200 from aJile Systems, Inc.. 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, this technology being named Jazelle
Java Optimized Processor^[2] for FPGAs. A PhD thesis is available
SHAP bytecode processor from the TU Dresden
jHISC^[3] provides hardware support for object-oriented functions
ObjectCore is a multicore Java processor designed by Vivaja Technologies.
