  2. fEST • Far • End • Speakerphone • Test • System

  3. Introduction

  4. Design constraint • Telephone line, ~300-3400 Hz • By Nyquist Rate, 8000Hz • 16-bit data depth per channel • Requires to playback and record four different audio files • MCU has only one storage media • Large, fast-access internal memory needed

  5. Computation requirement • FFT • Normalized LMS • Auto-correlation

  6. Interface requirement • SD card • USB* • 2 Push Buttons • Reset • Start/Stop • 2 Switch • LCD/7-Segment-Display • LED

  7. On-chip & Off-chip • On-Chip • Serial Peripheral Interface • SD Card • USB* • Off-Chip • DAC - To playback audio data from MCU • ADC - To record audio data to the MCU

  8. Power, packaging & Cost • A.C. powered • Back up battery necessary for 24-hour operation • Packaging • Portable • But handheld form factor not desired • Unique device

  9. Component selection • TMS320F-28035 MCU • Lower pin count, 128KB on-chip Flash • Other Options • TMS320F-28335 (same family, 100+ pins, 256KB on-chip Flash) • C5000 low-power MCU (500+ pins) • C6000 single-core DSP (700+ pins, BGA only) • TLV320AIC23 Audio Codec • Modularity • Extendibility • Other Options • PCM3008 (low-end, non-configurable) • TLV320AIC320, PCM3070 (non-hand-solderable)
