  1. Hardware accelerator for Efficient error-correcting codes Christine Kuhlman Northern Arizona University Mentor: Dr. Elizabeth Brauer

  2. Intro • Why is this important? • Static noise is an annoyance • Error-Correcting Codes can correct for noise • ECC • Evaluation of ECCs requires millions of cases • Software testing is too slow • C++ and MATLAB • Hardware accelerator Transmitter Noise Receiver

  3. Objectives • Gather Statistics • Display Statistics • Optimize Field Programmable Gate Array Speed • FPGA • Implement Realistic Code

  4. Hardware Accelerator • Gaussian Noise Generator • GNG • Low-Density Parity-Check • LDPC Transmitter “0000” GNG Receiver “0010” LDPC

  5. Data • Taken using Cyclone II • Programmed in VHSIC Hardware Design Language • VHDL • FPGA implemented

  6. Analysis • FPGA vs. VHDL • FPGA vs. C++ or MATLAB

  7. Conclusion • Most important part • Functional hardware accelerator with a realistic code • Future work • Even more complex codes • Add LDPC • Tool to evaluate ECC

  8. Acknowledgements • NASA Space Grant • Dr. Elizabeth Brauer – Mentor • Dr. Sheryl Howard • Mike Thomson
