a superscalar implementation of DES (1 clock per round, 16 rounds
of hardware) gives 6.7 Bps/64 bits per block or 104+ MHz clock.
Should be able to do static key distribution accross the device, and
11 gate levels per round. That gives a number around 880 ps per gate
with routing. Should be able to go 3 or 4 times faster. At least
twice as fast with routing distances.
You could also do a dual pipline...
