Hi
We are using adsp 21364 for audio processing application.I want to
know is there any advantage for SPI booting over parallel port booting

So it can reduce overall cost and size of a project. But it's slower since you only get 1 bit at a time versus 8, so it takes longer to wake up. Depends on what is more important for your application. Patience, persistence, truth, Dr. mike

SPI serial flash uses a small 8 pin part. Parallel flash uses a 32 pin part. Do you really want to route all those signals to a much bigger part for no real benefit?
