  1. FPGA System Development Colin Orsborne Can Koklu Calvin Kwok Paul Richardson

  2. Purpose • Offloading methods from a Java Virtual Machine for execution on a FPGA

  3. Roles • Colin • Runtime profiling • Assist with JVM modification • Paul • Modifying JVM • Calvin • Interface design and implementation • Can • FPGA design and implementation

  4. JVMs and Runtime Profiling Colin Orsborne

  5. Intro Into a JVM • Extract bytecodes • Two JVM Candidates • Jikes RVM • In Java, Larger, good documentation • jamVM • In C, small, poor documentation

  6. Profiling • Value Profiling • Temporal Profiling • Jikes RVM Profiling Infrastructure • Instrumented event counter at runtime • Overhead

  7. 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

  8. Questions and Answers?
