Evaluation board recommendations


I am looking for a dsp evaluation board for a proof-of-concept project at work, and I would appreciate some input on what to choose.

The project is fairly simple on the processing part: All I need to do is add some delay (probably 0-5 ms, max 20 ms), and attenuate the output (at least for now - if the proof-of-concept works, then perhaps it could be interesting to add more advanced stuff later. But my boss might prefer simpler and cheaper).

The problem is that this must take a single analog input, and produce at least 8 analog outputs with individual delays and attenuations (8 is the absolute minimum, but I would prefer having the option to have 12-16 or more outputs if possible).

Also, I have been looking at Audio DACs (https://www.analog.com/en/parametricsearch/11079), and noticed that some of them can be daisy-chained, which lead to the question: How many analog channels is it possible to support on a single digital channel?

    Analog devices’ SHARC processors are good for Audio applications, we suggest you to have a look at the SHARC processor which offer a mix of high performance processing with the large on chip memory and peripheral set in a low cost floating point product. The new series provides designers with end-to-end SHARC family code compatibility and a robust suite of ADI development tools to realize new levels of development efficiency and design innovation via the industry’s highest-performing 32-bit floating point DSP platform.

    You can find the advanced SHARC Family Features here,
    • Dedicated hardware accelerators (FIR,FFT,IIR etc)
    • Variable Instruction Set Architecture (VISA) support
    • Audio-centric peripherals and dedicated on-chip decoders
    • Low power attributes and 105 degree C ambient operating temperature tolerance

    We would suggest you to refer the selection tables of SHARC processors, which can be found in the following link.

    Please use the below parametric search link to choose the processor,
    We have Processors Software and Tools page provides a convenient look-up table to indicate to users what evaluation platforms, extender cards, emulators, software development tools, and middleware are available for the specific SHARC processors you have chosen to evaluate.

    For more details on pricing and availability of evaluation kits please contact your  nearest ADI sales office or authorized distributor. To locate one,
    go to www.analog.com/adi-sales

    If you can provide more information on other requirements from the external interfaces, the speed grade, memory requirements, package, which you are looking for, then we can help you narrow down to select the right derivative in the SHARC processor family.
