I was wondering if there are any PALs/GALs that have a large number of D flipflops. I need to implement two 12-bit counters and a 15-state FSM and and 8-bit
register. I also need three 8-bit I/O ports. I want to design a controller
to act as a pseudo-Dual port RAM controller, with a high speed 20ns RAM chip
(single ported) attached to one of the ports on the PAL/GAL, and the PAL/GAL
acting as a time slicer for the RAM. One port on the PAL is read-only, the
other is write-only.
Any help in this area would be much appreciated, as going with external
