McASP data pass through with minimal delay

Hi Community

I'm trying to find a best way with regards to the delay to pass audio data through my C674x DSP. In the current case, the audio data are received at McASP2 and transmitted by McASP1. I'm aware of the standard ping/pong buffer solution but I need to reduce the delay as much as possible. The audio data need really no processing in that case - just a past through is needed.

Is there a way to copy the incoming samples from McASP2 XRBUF to the McASP1 XRBUF directly (without additionally buffers)?

Cheers
