Hi,
have never done any DSP using dedicated chips and have a project which requires monitoring between 75kHz and 150kHz with the passband variable between these frequencies. Outside this range needs to be blocked. Its for sonar for cetacean monitoring. I have experience of designing the code for doing the DSP using Matlab which seems straightforward enough.
What I'd like are recommendations for a capable DSP development board (or chip) with reasonable power consumption and speed, - I require miniumum phase distortion (so FIR I expect). Ideally I would like to use an existing [modestly?] priced development board with 2 AD channels (10-12 bits) and at least 1 DAC channel to test code as its developed. The DAC needs to be able to work up to 150kHz to test the filter response using a signal source to the inputs.
I am expecting the filter would be notch bandpass with a variable width depending on what noise I want to reject but between 75kHz and 150kHz as mentioned.
Anyone got any suggestions for a development board that might work for this.? Even better
suggestions for a few boards, I am guessing TMS320 variants as these seem to come up a lot
although other sonar stuff I have noted use Blackfin and Sharc.
Regards
Rob
