FPGA System Development Colin Orsborne Can Koklu Calvin Kwok Paul Richardson
Purpose • Offloading methods from a Java Virtual Machine for execution on a FPGA
Roles • Colin • Runtime profiling • Assist with JVM modification • Paul • Modifying JVM • Calvin • Interface design and implementation • Can • FPGA design and implementation
JVMs and Runtime Profiling Colin Orsborne
Intro Into a JVM • Extract bytecodes • Two JVM Candidates • Jikes RVM • In Java, Larger, good documentation • jamVM • In C, small, poor documentation
Profiling • Value Profiling • Temporal Profiling • Jikes RVM Profiling Infrastructure • Instrumented event counter at runtime • Overhead
Two Virtual Machine Candidates: Jikes RVM and jamVM Profiling Temporal Value Goals Selected bytecodes for execution on FPGA select time consuming methods for future execution on FPGA Modified RVM or JamVM Conclusion
