GStreamer Plugin to communicate with DSP

Hello All,
I am working on beagleboard from almost 2months or so. I have used
GStreamer for video capture purpose. I would like to use the DSP for
some video processing.
Is there any ready gstreamer plugin is available for communication
between ARM & DSP ?
Or
Do i have write my own plugin for that ?
Waiting for suggestions.

Thanks,
Amol
