TDA4VM: Integration of Custom Kernel

Hello,

I created some custom kernels with the PyTIOVX tools.

I generated following directory:

Now I like to integrate them into my graph.

How do I accomplish that?

I know that I have to create a generic node with my custom kernel.

I am confused with the imports I have to do and how I get my custom node from a custom kernel.

Looking forward to see some answers.

Best regards

Hi Daniel,

Once you have created a custom kernel using the PyTIOVX tool,
you could find the node API that could be called from applications in include folder generated.

I see that you are trying to run the target as A72. Am I correct?

You should call the Register and Unregister functions of target and of host available in vx_imaging_target.c and vx_imaging_host.c respectively in the application before you could use the node API.

Please refer the below link on how to integrate the custom kernels
TIOVX User Guide: Adding Custom Kernels

You could also refer the kernels present in the vision_apps/kernels folder for reference.

Regards,
Nikhil

Hi Nikhil,

thank you for your reply.

What is the next step after the registration of the kernel? Or do you have a good example of an app and a custom kernel?

Best regards,

Daniel

Hi Daniel,

Please refer the demo in ch03_graph in the file path PSDKRA/tiovx/tutorial/ to integrate a custom kernel "phase_rgb_user_kernel" in the example vx_tutorial_graph_user_kernel.c.
