Introduction to GALS and PALASM (2020)

  >"...we can condense a few 74LSxx circuits into a single GAL." (LS = Low Power, Schottky) -- 74LSxx are basically 74xx IC's. Those are the kinds used for building simple computers without discrete CPU's (combinations of 74xx IC's as a group function as a simple CPU in those designs...) Apparently (if this article is correct, and I see no reason why it isn't), several 74LSxx / 74xx IC's can be replaced by a single GAL... Thus, for the simplest of simple educational breadboard computer designs, a GAL or several GAL's (to implement the simplest of simple CPU's) might be the way to go -- whereas a modern FPGA might be overkill... Anyway, very interesting article!
