Hi guys,

I'm designing a real-time audio project, in which I want the FIR filter's coefficients get updated frame by frame (TMS320C6748+CCSv5).

My first problem is that I can only use matlab FIR filter design toolbox to calculate the coefficients, and then import the coefficient file into CCS, is there any library or function that can be used to calculate the coefficients directly in CCS?

Another problem is that, if I just want to use MATLAB to get the coefficients, how do I communicate MATLAB and CCS so that the coefficients are updated frame by frame? Right now I can only implement one frame and couldn't find a way to update the coefficients using matlab in real-time process. Thx in advance.
