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.cite-ref-webopedia-1-0[1] GNU Compiler Collection added picoJava support in 1999 as machine definition 'pj,'.cite-ref-gcc-ml-2-0[2] The open-source version of picoJava has been implemented in an FPGA.cite-ref-pj2-in-fpga-3-0[3]
