No, this isn't about picking up girls, you're still on your own there. Instead we're talking about Generic Array Logic devices. The uC Hobby blog posted a good introduction to GALS that explains what they are and what you can do with them. "GALs are the simplest member of the programmable logic family that also includes CPLDs and FPGAs. They are the modern replacement for the one-time programmable PAL devices that were first introduced in the late 1970’s. Unlike PALs, GALs can be erased and reprogrammed many times. And unlike CPLDs and FPGAs, GALs don’t require using a hardware synthesis language like VHDL or Verilog, or any other special design tools."
