A Java processor is the implementation of the Java virtual machine (JVM) in hardware. In other words, the Java bytecode that makes up the instruction set of the abstract machine becomes the instruction set of a concrete machine. These are today the most popular form of a high-level language computer architecture.
Implementations
There are many Java processors available, including:
- picoJava was the first attempt by Sun Microsystems to build a Java processor
- Cjip from Imsys Technologies. Available on boards and with wireless radios from AVIDwireless[1]
- 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
- jHISC[3] provides hardware support for object-oriented functions
