Java processor

A Java processor is a microprocessor that uses bytecode as machine language. So that they are in competition with Java virtual machines such as interpreters and just-in-time - compilers .

Most Java processors exist as IP cores and are used in FPGAs or ASICs .

Examples of Java processors are:

• picoJava from Sun Microsystems
• PSC from Patriot Scientific
• “Jazelle” extension for ARM processors , to be found in many Java-enabled cell phones.
• JOP (Java Optimized Processor) - a Java bytecode processor that is available as open source for FPGAs .

The Atmel AVR32 can execute bytecode directly in hardware, but it is not a full Java processor.
