SDR DSP Development board

You don't need a cannon to kill the flies.

I have TMS5510 EzDSP that I would like to get rid of for half price.

I used a Motorola MC56k development board for a similar task, with 9600 samples/s.

The board is now obsolete, so there's no help for you if I give the exact type for you.

Do you need a DSP board? At that frequency a PC with a good sound card will suit you just fine.

The problem is that it is a low bit rate radio with sychronisation timing constrains , hence have to make the receiver coherent. Also the environment(s) are really noisy so need a lot of processing gain and equalisation. Thats the reason I am wanting to go for a DSP with clout for research and development phase and then I can drop MFLOPs.

I am using a DSP library which has optimised support for C67xx and ADSP floating point devices.

If the receiver is coherent, then the PLL acquisition time adds to the total synchronization time.

Does the ADC response have to be all way down to DC ?

"Really" and "A lot" are not the engineering terms.

Then use a PC with a sound card for R&D.

This is what they call "premature optimization".

All thing you are saying are true. The uncertainties ( really and lot of :) ) are due to a totally novel channel/medium. The characteristics of which I cannot discuss , so apologetically I cannot continue discussion on that. Was only looking for advise on DSP boards without the extra bells and whistles they usually come with.

I am in the process of setting up an environment for using a soundcard , i am looking at a software called Portaudio to access the soundcard.

Also I am looking to construct a front end to connect to the soundcard.

I am eager to start the embedded side of development because a PC based simulation hides a lot of embedded issues.

Any advise on a DSP(and ADC doughter card) board with should BSP should be gratefully accepted. Thanks

The entities should not be multiplied beyond necessity. The standard windows wave API functions will do; it is all described in MSDN.

Could this be a problem?

So you really do that for enjoyment of the process rather then to get the result, right?

Hire the consultant.

Look at port audio it is interesting!

Also, if like a sizable portion of the people here you are using Matlab, the data acquisition toolbox can access a sound card.

Thanks chris.
