Niels,

The Spartan 3 doesn't cost that much. What's in the firmware is what
makes them expensive.

Not really. And it's only a few thousand.

Well, there are constraints, like the number of dedicated multipliers,
you have almost no storage capabilities and so on. But if you think of
the 8192 mixers for example a MADI card has to calculate for each sample
period, you can use a divide and conquer strategy to add up the data and
be done with it in a matter of a few cycles. After all, 64 is a nice
two's complement :)
