In my ADSP-BF548 design, is it possible to aquire data from 3 CMOS sensors
using the three EPPI ports with dedicated DMA channels?

 

Yes, that is possible with the following data width restrictions in mind: EPPI0
up to 18-bits, EPPI1 8-bits and EPPI2 8-bits. As for dedicated DMA Channels,
EPPI0 always connects to DMA Channel 12 only, while EPPI1 and EPPI2 share DMA
Channels 13 and 14. For more details please refer to the EPPI chapter in the
ADSP-BF54x Blackfin Processor Hardware Reference.

This same applies for all ADSP-BF54x processors except the ADSP-BF542
processor, which does not have EPPI0.
