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.

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.
