Texas instruments 6711 dsk
- Digital Signal Processing Board with PCM3003 Audio Daughter Card
The DSP board is responsible for the high-speed DSP calculations and the daughter card controls the A/Dand D/A conversion between the DSP board and the outside world.
- Specifications of the DSP board and daughter card are as
follows:
- TI TMS320C6711 floating point DSP processor
- Software-controlled adjustable sampling rate (8, 9.6, 12, 16, 24, and 48 kHz)
- 16-bit stereo audio codec with two on-board microphones. A lowpass anti-aliasing filter at the input channel with a fixedcutoff frequency = 24 kHz
Software:
The software used in the lab is National Instruments LabVIEW DSP Module ; a block diagram-based graphical programming package for digital signal processing thatwill be used for: data acquisition, time domain data display, frequency domain calculation and display, filter implementation,convolution and correlation calculations, speech/signal modeling, and real-time filtering. Using LabVIEW DSP Module in conjunctionwith the LabVIEW Digital Filter Design Toolkit, the DSP board and the rest of the lab equipment will not only allow students toperform data acquisition, analysis, and filtering, it will also give them the ability to listen to the filtered output.
