Design Recipes for FPGAs

What is clear from this report is the fact that a significant amount of
resources were required to implement this multiplier on a standard
device. In this case, the optimization was for area and not speed, but
in spite of that, the design usage was nearly 50 per cent of the
whole FPGA (Field Programmable Gate Array), so clearly arith-
metic functions are not always easy on an FPGA, certainly not in
area terms, with the worst culprit being multipliers.
As a result, care must be taken in managing designs, taking advan-
tage of pipelining and using the available resources as effectively as
possible. The downside is that the design ...
