hello guys,
can some one post code for cic decimator. ?

Heck, just write it yourself.  It's a do-job.



Steve

well, you can steal mine for a start.

BTW note that it's pretty useless as a standalone solution for
homework-type problems, as it doesn't implement a CIC decimator but
_models_ it in floating point.

Yes, I can (C++). How much is it worth for you?

You may read my article published in Circuit Cellar magazine #231, October 
2009 ("the Darker side - multirate techniques and CIC filters"), there is an 
exemple of a small CIC filter coded in C on a PIC microcontroller. Very 
basic but it could be a starting point... Article available in your good 
local library or available here but not for free :

If you just want the source without the explanations see there :
