implementation of Digital filters in FPGAs

[anand_biomedical]

Hai all,
I would like to implement 2nd-order IIR digital filter in FPGA. I wrote Matlab code and I found the block diagram. But Im not sure how to implement in FPGA.
Any help is greatly appreciated.
Thanks

In my opinion you must use fdatool in matlab to design a filter you want. When you will have coefficients write a code in vhdl or verilog which will working like in block diagram or you can generate code using core generator in Xilinx ISE 7.1 or uper and that implement it to fpga.

You can also use LabVIEW FPGA to program an National Instruments FPGA target (Xilinx Virtex2 inside). There is a toolkit for Filters available

If you have the money, you can get system generator with simulink. That will allow you
to design your filter and genearte the VHDL code for you. But if you don't have any
money (like me), you will have to compute the coefficients and implement the filter in
vhdl by hand.

Hi

Try this read the book "Digital Signal Processing with FPGA"

it has many examples of filters implementation using VHDL scripts:

In the name of Unique
See MATLAB R2006a new part: Filter design HDL Coder.
It may be usefull.
