  1. Thesis Proposal Template Recognition of Bytecodes and Execution using Hardware Architecture. (Vectorization of Java) by Ian Reddy

  2. Progress - Used Java assist to write a program - which can recognize loops, recognize arrays - recognize arrays embedded within loops - from bytecodes. - trying to enhance this program to read profiler output, - Next, -How can I accelerate these patterns. -The process should be fairly automated.

  3. Progress ..... Literally Stuck ! Option 1 - Encountered several programs, which can convert bytecodes to C - tools like TOBA, HARRISA, JC claim to achieve this conversion -all these tools are abandoned projects (not touched for over 5 yrs now) - they use older versions of JDK -failed to get them work, even tried to manipulate their source code. - the HARRISA would build, but the executables fail

  4. Progress ..... Literally Stuck Option 2 - Looked into some open source virtual machines, - looked into the JC, mentioned previously. - working on the KAFFE virtual Machine, - Trying to get KAFFE VM, recognize patterns, - Accelerate them by modifying the VM code. - Fairly complex Job

  5. Progress ..... Literally Stuck Option 3 - Working on the GCJ for LINUX , - GCJ is built on the GCC , - GCJ is like a front end to the GCC (documentation states) - GCJ can read bytecodes, - can I use GCJ to pass options to the underlying GCC, - the underlying GCC, may be optimized for certain architectures.

  6. Progress ..... Literally Stuck Option 4 - I can introduce calls to native methods, which already exist - these methods may have been manually written - would make a call only if method exists - will not be automated - will lead to another high performance library.
