Since the necessary modules needed to interface with peripherals can be part of the initrd, the kernel can be very small, but still support a large number of possible hardware configurations.
Digital Audio Interface (DAI) enabling user-definable access to peripherals including 8-channel asynchronous sample rate converter.

This interface uses a peer-to-peer architecture in which peripherals negotiate bus conflicts to determine which device can best control a data transfer.
