I am a beginner and am interested in using the Blackfin processor for some audio processing applications. Can you guide me through right from what I should buy, and if there is an A/D converter on board? Should I buy an extender board also?
The ADSP-BF533 and ADSP-BF561 processor EZ-KIT Lite boards have a codec, AD1836 on the board. You can use this for A/D conversion.
To start with, you can get an EZ-KIT Lite Board for the processor you choose. For higher working speeds (with respect to loading the application to the processor etc.), you could also get a HPPCI-ICE emulator.
To go ahead with the purchasing of ADI products, you can contact your nearest ADI Sales/Distributor office at: http://www.analog.com/salesdir/continent.asp You can also download the trial version of the VisualDSP++ (Development Tool) software that is available on the Analog Devices website: http://www.analog.com/processors/visualDSP/testDrive.html
Once you have all the hardware ready, you can read the analog signal by using the codec on the EZ-KIT Lite board. We have example codes that take in a signal from the ADC and send out a signal to the DAC. Once you install VDSP++, you could have a look at the codes (Talkthrough codes) in the VDSP++ Installation path. …\Analog Devices\VisualDSP 5.0\Blackfin\Examples\ADSP-BF533 EZ-Kit Lite
If you purchase an EZ-KIT Lite board, and the AD1836 codec suits your application, then you will not need to buy any extender boards for reading an analog signal. You could also go through the DSP Selection Guide which is available at the following location: http://www.analog.com/processors/EP_DSP_Sel_Guide_2006_Web.pdf
You can use the free audio Software Modules to get you started. Each of these modules has its own EZ-KIT, Extender board and Tools Update requirements.
I wouild suggest instead of point to the url: http://www.analog.com/processors/EP_DSP_Sel_Guide_2006_Web.pdf to point instead to www.analog.com/blackfin since this is a Blackfin specific question.
