picoJava is a microprocessor specification dedicated to native execution of Java bytecode without the need for an interpreter or just-in-time compilation. The aim is to speed bytecode execution up by up to 20 times, compared to standard Intel CPU with a Java virtual machine.

GNU Compiler Collection has been available until version 3.2.3 as machine definition 'pj,' probably first patch was for version 2.9.[2]
GNU Binutils is still available as machine definition 'pj,' as of Binutil version 2.28. GNU Debugger was once implemented, but code might be lost. Sun Microsystems provided instruction set simulator worked with GDB as SCSL open source code.
This approach results in the fastest Java runtime performance with a small memory footprint and competitive performance on code not written in the Java language.
The picoJava specification does not include any memory or I/O interface logic, so that developers can add their own logic to customize memory and an interface.
