Hey Tricky,

yeah, xilinix has DSP48E1 whcich can do complex operations like (a x b) + c.

Altera say they have this kind of dsp ( Variable Precision DSP in Arria V Devices ).

http://www.altera.co.uk/literature/hb/arria-v/av_52003.pdf.

But don't know how to use them / infer them.

I can do (a x b) + (c x 1) but which takes 2 dsps. Than 2 dsps going for luts is best option i think.

Thanks.
