While not as clear as it could be I think the question is: "Will you give me MATLAB code for doing echo cancellation with the tms320c6713?"

There are many answers to this question. The simplest form of echo cancellation given input x and output y is

y = zeros(size(x));

This completely cancels any and all echoes and can be efficiently implemented on a dsp. It works on 1-D (e.g., sound), 2-D (e.g., images), 3-D (e.g., video) and N-D inputs. It does have a drawback of having considerable signal attenuation.
