FPGA/GAL/PIC for port expansion/conversion
Depends on your speed/power requirements, and things like glitch
tolerance, clocking requirements etc. There would probably be little to choose between a PIC and a GAL in
terms of cost and board space. If you want the highest speed, a GAL is the clear winner. For minimum
power, if speed is not an issue, the PIC would have the edge
For minimum power and maximum speed, hardwire it with some CMOS gates.
