Harvey
From JopWiki
Harvey is a package for implementing the picoJava processor in an FPGA. It is developed and maintained by Wolfgang Puffitsch. The package contains the hardware blocks that are missing from the code Sun provides, and software to make Java code run on the processor. All parts are open source (LGPL, Apache License), so the package can be modified and redistributed freely.
Currently, Altera's DE2 board is supported and a number of benchmarks are working. The library contains only the most necessary classes yet. Garbage collection and threads are not supported currently.
