TDA4VM: Running Graph on DSP C66

mudasar kalwar

Part Number: TDA4VM

Hello,

I have a graph which is registered as a

vxCreateGraph, and Pipeline is enabled with vxGraphParameterEnqueueReadyRef, it is running perfectly on Arm CPU of Jacinto 7.

My question is I want to run that graph on DSP C66_1, instead of ARM CPU,

previously I was using a node and configured the node like "vxSetNodeTarget" to run on DSP.

Is there anything similar for Graph to be configured so it run on DSP?

how can I change application configuration so it run on DSP, whole application.

Thank you

Hi Mudasar,

Graph can only run on host core, which is A72 in the current implementation of the OpenVX, so it is currently not possible to run graph on DSP. Any specific reason you want to run graph on DSP and not from A72?

Hi Brijesh,

Yes, because the performance, A72 is bit slow. DSP runs faster as you know.

Hi Mudasar,

But the graph does take much processing, Graph just delegates the tasks to other cores and there is very less processing happens on graph running on A72.

Could you please provide some more information as to what performance issue you are observing in running graph from A72?
