The best resource for this is the DSP48 users guide for whichever part you are using (Virtex 4 or Virtex 5). Xilinx also has a few customer education training courses that can assist in DSP design using the DSP slices. You can find training information at http://www.xilinx.com/support.

Hi,

 

The DSP48 is essentially an ALU. The operation that the DSP48 performs can be changed from cycle to cycle in real time.

 

The user guide should answer most of your questions!!
