That of course is a very general question ;-) * GAL is an old chip, comparable to the PLA of 8-bit Commodores plus flip-flops at the outputs. CPLD is bigger, has more IOs and more flexible architecture allowing for much more sophisicated design. * CPLD is harder to program and will need a special JTAG programmer, GAL should be programmable by a decent EPROM programmer as well (at least that's what my programmer advertises, never tried that) and building your own GAL programmer is easy. * It is hard to find 5V CPLDs now, the old Altera and Xilinx ones are rare and expensive. I personally am working with Atmel 15xx chips which are still available. * Basing on the complexity, I am surprised about the price difference you are quoting, it should be the other way around. I am sure you will be able to find much cheaper GALs/PALs, but you will not find cheaper CPLDs. Regards, Michau. Message was sent through the cbm-hackers mailing listReceived on 2012-09-18 08:00:04
