Implementation Plan
  • DSP
  • Complete CELP decoder and speaker hardware.
  • Receive CELP file from ARM.
  • NIOS Hit Processing
  • Complete findHits().
  • Write to SRAM.
  • Notify ARM of database hits.
  • ARM
  • Implement extendHits().
  • Read from SRAM,
  • Forward CELP file from Flash to DSP.

8
Verification and Test Plan
  • DSP Card
  • Verification of C neighbor word pre-computation
    algorithm with Matlab reference code.
  • Verification of signal demodulation by comparing
    with original amino acid sequence.
  • NIOS Processing Core
  • Verify custom hardware in Verilog simulator.
  • Verify custom hardware interface to C code.

9
Demonstration Plan Demo 2
  • DSP
  • CELP audio demonstration.
  • Stable communication protocol with NIOS.
  • NIOS
  • findHits() for a single database string fetched
    from the server.
  • ARM
  • forwardCelpEncodingToDsp()

Division of Labor
  • Elliott
  • DSP audio receive and playback.
  • Mike
  • String matching combinational logic.
  • Jon
  • Custom instruction interface to hardware.
  • Naju
  • Latch control for matching hardware.
