Dear 

Does C55x support ABU mode like C54x? If yes what is the related document 

from TI? If no, how can I convert my application working on C54x to 

application for C55x?
What is the differencies between ABU mode and using DMA auto 

initialization for autobuffering of MCBSP's data?
In my application I have three I/O devices which provide speech data 

streams for my software application. I use these devices through McBSP 

but because the sampling rate of this devices is low (8KHz) and I should 

process a 540 samples block of each one the waiting state for each one is 

long and the processing time for each one is also long. How can I exempt 

the receive and transmit time for I/O data?

Regards
