Here's an important update:
I just gave the new design one hour of debug time...
Nothing is fine yet, many features still untested (interrupt, mq, memory
BUT: It currently runs Chekmo at 100 Mhz!!!
There are some severe synthesis warnings I simply ignored. Will
investigate in the process of further debugging the stuff.
A 100Mhz Chekmo is a big step forward. And all that on a Spartan-3. On a
Virtex-2 or -4 FPGA this would become even faster.
