Hello BadOmen.

Thanks for answering. The Filterorders and coefficents are calculated by matlab. I will upload these datas

via my host pc software to the nios cpu. The nios should than disable or enable some of the TAP's or biquad

sections to get the right filterorder. The filters should be on the fpga. For the coefficents i have thought about an lookup table feed by the nios cpu but i have no idea on how to do this http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/huh.gif

The filter should work on 100Mhz if possible. The AD converter is connected to the cyclone.

I&#39;m a newbee and i have no idea on how to begin so any

guidelines or code segments to get an introduction are welcome.

What should i do first ?

Thanks

Andreas
