You can use toolboxes of Matlab (I don't remember whether the Signal Processing Toolbox, Filter Design and Analysis Tool, or the Filter Design Toolbox) for easily obtain the coefficients of the filters you need, from the filter specification.
I have questions again. I am using the FIR Compiler where there is a section that say "use reloadable coefficients." when i select this tick-box, coef_ld, coef_we and coef_din will be highlighted in the IP symbol of the FIR compiler. I want to know how do i continue with it to make the poly-phase fir filter programmable. Is there any example codes or guide that i can follow? I tried reading the data sheet of the FIR compiler but i am still not able to do it. Thanks in advance
