• FPGAs vs. CPLDs
• Are FPGAs and CPLDs the same thing? No. Both are
programmable digital logic chips. Both are made by the same
companies. But they have different characteristics.
• FPGAs are "fine-grain" devices. That means that they contain a lot
(up to 100000) of tiny blocks of logic with flip-flops. CPLDs are
"coarse-grain" devices. They contain relatively few (a few 100's max)
large blocks of logic with flip-flops.
• FPGAs are RAM based. They need to be "downloaded" (configured)
at each power-up. CPLDs are EEPROM based. They are active at
power-up (i.e. as long as they've been programmed at least once...).
• CPLDs have a faster input-to-output timings than FPGAs (because
of their coarse-grain architecture, one block of logic can hold a big
equation), so are better suited for microprocessor decoding logic for
example than FPGAs.
• FPGAs have special routing resources to implement efficiently
binary counters and arithmetic functions (adders, comparators...).
CPLDs do not.
• FPGAs can contain very large digital designs, while CPLDs can
contain small designs only.
