  2. Overview • Misc. Parts • Micro-Controller • DSP

  3. Block Diagram

  4. Miscellaneous Parts • Filter Components • Very Low Tolerance Inductors/Capacitors • Audio Amp • Low Noise • LCD • ADC • LTC1400CS8#PBF – Linear Technology Company • 400 KSPS • Power Supply Components • Wall Powered

  5. Micro Controller Considerations • SPI – Communicate with DSP • Communication to LCD Display – SPI/UART • File Transfer– SPI/I2C/UART • User Input – General Purpose IO/Quadrature Encoder • Timer – Metronome • Potential Micros • PIC24EP512GU814 • PIC32MX575F256H • PIC24FJ256GB206

  6. DSP Constraints • DSP Choices • Blackfin – FAST • 400 MHZ, 800 MMACS • On Chip SRAM – 116 kB • dsPIC – Included ADC • 40 MIPS • On Chip RAM – 30 kB
