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
