Depend on how much else are going to be there. I have not yet gotten any
good estimates on EC implementation sizes. It also depends on how much
is done in HW. Considering the myriad of side channel issues surrounding
EC (esp NIST and IEEE curves) one might want to do quite a lot in HW.

RSA is easier and can be partitioned a number of ways. The big thing is
getting a good/fast exponentiation that is side channel silent and that
can be done in HW.

But I might be getting ahead of myself.

For quite a few of our use cases, the TerasIC board seems to provide
ample HW resources. And so does the Novena. Smaller boards like the
Nano-DE0 might be usable as a key store, DHE-accelerator and/or simply a
TRNG.

When we have more components we cam start looking at assembling a few
different systems for different groups of use cases.
