implementing IIR bandpass filter in FPGA using verilog code

verilog iir

Hi,
I need to implement 2nd order IIR bandpass filter in FPGA using verilog code.
2nd order IIR bandpass filter transfer function is

H(z) = (0.13875 - 0.13875z-²)/(1 - 1.6614z-1 + 0.7225z-²)

(Note:In above equation z-1, z-² are nothing but z power -1 , -2.)

center frequency is 24.6875 Hz
lower -3db frequency is11.975 Hz
Higher -3db frequency is 37.4 Hz
-3db bandwidth is 25.425 Hz

I used matlab to come up with the coefficient values.
I used Direct form II realization and ended up with four summers, four multipliers and two delay units.

Now I am worried about verilog code for the bandpass filter whose input going to be an 8-bit digital signal and expected output is 8-bit. I installed Xilinx ISE webpack 8.2i, but I dont know how to write verilog code in this package

If anyone could suggest me that would be great.
I am really looking for any help.
Happy New Year!!!!!

Thanks

fir notch filter+ verilog code

use fdatool in matlab to design the filter quantize it to 8 bits(ur specs) and generate verilog code for that...
this is synthesizable in 8.2i
it would be really simple.

vhdl coding for iir filter realization

O.K., using FDA tool I can design the filter, but I wonder how to generate verilog code. Does FDA gonna do it?

look at this book
Digital Signal Processing Programmable Arrays
u will find chapters on it . and you may download it from
