A SPLD that has a programmable AND array and a fixed OR array is PAL; PROM; PLA; GAL 8. A SPLD that has a re-programmable AND array is PAL; PROM; PLA; GAL
1. A GAL is different from a PAL because A GAL has more inputs and outputs; A GAL is implemented with a different technology; A GAL can replace several different PAL's; A GAL can be reprogrammed and a PAL cannot;
2. To program a given PLD device, you need only a special fixture; a special fixture and a master PLD that has been preprogrammed at the factory; a computer and a programmer; a computer, a programmer, and HDL software; a computer, a programmer, and BASIC software;
3. Explain the difference between the registered mode and the combinational mode for PLDs
