[Coco] MPI replacements?

[jdaggett at gate.net]

How small is small?

Discrete logic may have an advantage over usign a CPLD in that you will need only one 
power rail as compared to two or three depending on CPLD. Cost wise neither maybe all that 
different. 

A discrete version can be down with SMT parts that would reduce size. The only discrete part 
that is not SMT that I know of would be the PAL chip. I have no means of programming one. 
That is where a CPLD would come in handy. Those equations are easily done in VHDL. In 
fact much of the circuit is relatively simple. Could almost do it with the schematic entry for 
either Xilinx or Altera software.
