TDA4VM: Can tflite-runtime be used inside an openVX graph node ?

Hi Victor,

As TFLite sets up OpenVx sub-graphs in the delegate functions, its unlikely that this can be wrapped in an OpenVx node and connect it to another graph running on A72.

Hi Shyam,

Thanks for the useful information.

Is it possible to connect a camera capture node and display node to an openVX graph generated by TF-lite ?

regards,

Victor

Hi Victor,

Yes this should be possible,

You can split your application into 3 parts,

1. OpenVx graph1 - CSI-Rx -> VISS -> LDC -> MSC -> Pre-Processing (Get output in RGB/BGR planar data)

2. Use DLR RT or TFLite RT

3. OpenVx graph 2 - Post-processing -> Mosaic Node (if required) -> DSS

Note at the boundaries of DLR-RT, currently it might require a copy back and forth. But it should be possible to avoid this if all buffers are allocated in DDR_SHARED_MEM and there is a way to tell the DLR-RT.

Regards,
Shyam
