Multiply add Block and How to cope with the problem of the lack of ressources

Hi,

In a very general sense:

1) reduce your multiplication at source

2) think of time sharing(TDM) if you can go faster...

3) reduce datawidth to 9 bits or less than 18 bits

4) think of using soft multipliers(horrible on memory)

5) use addition if you can to replace or pre-add then multiply

6) think of any possible premultiplication of results and store in LUT

7) use larger device

8) avoid DSP builder, Do it Yourself

9) give up
