Are you using some kind of compiler/optimiser that will let you look
at the optimised equations? To state the obvious, if you have a total
of N states and inputs you have a lookup table of 2^N entries. The
width of each entry is the number of outputs you have. If you have a
limited number of inputs and lots of memory, the solution is
straightforward. Roadie Roger
