I have faced the same problem. I believe there is a (expensive) matlab tool that will target c67xx, but I'm not sure. And there are issues. Has the code been written with real-time issues in mind? I suggest you just convert to C. It should only take a few days work. Use a mex file to develop the real-time code in matlab first. Then port it to the dsp. This should be very easy if you think about what you're doing before you start coding. There may be some sample code on my home page. -- -Todd http://www.signalsguru.net/

You will likely need to convert the MATLAB code to C or C++ since MATLAB doesn't run on DSPs. There may be some automated tools that can do this for you (I could be wrong, but I think the MathWorks' conversion tools only work for platforms already supported by MATLAB since they require you link their libraries in). I'd suggest you ask in a MATLAB newsgroup for help doing this. Cheers! --M

we are currently working on echo cancellation using adaptive filtering on
dsk 6713. we have implemented fir low pass and high pass filters on the
board using CCS.
we have developed L.M.S algorithm in Matlab(Not the Blockset provided in
Help. A new one). 
we want to download that m file on the board(Portability between Matlab
and Code Composer Studio).
How ?
