DSP usage in Beagleboard

Other Parts Discussed in Thread: DM3730

Hi All,

There are a couple of video and graphics related subsystems in dm3730 of beagleboard (IVA, DSP, SGX). And there are these gstreamer, dmai, codec engine and codecs layers from the sw perspective.

Lets say I play a youtube video in rowboat android gingerbread with dsp enabled. Could you guys please enlighten me with what all things happen behind the curtains?

What all hardware and software subsystems/pieces involved and what is their role? Any pointers to the docs, if needed for in-depth understanding, will be helpful?

Thanks,

Satish,

Thanks for the response!

I am looking for the internals as to the control and data flow from the application to the omx/gstreamer to dmai to dsplib to dsp and so on. I have searched in the net for details. But, I couldnt get the exact info. Even code/doc pointers will be helpful for us to dig in and understand more.

Please forgive my ignorance.

Also, I couldnt understand the need for DSP as well as IVA for displaying video. Are they integrated into one chip? For dispatching work to IVA, is DSP interaction from MPU needed?

Thanks,

Hi KK,

1. I am not sure if some doc avaialbe for control & data flow for omx

regarding your question....

IVA : used for video decoding purpose

while DSP can be used other analytics like speech/audio codec, blending, object detection algorithm etc.
