TDA4AL-Q1: c7x kernel using application

Hi Kwanghyun,

Could you clarify what part of the example code you are trying to modify? I'm assigning your question to our appropriate expert.

Best,

Asha

This example is about frame adding example.

I want to change the adding kernel to another one such as multiplying weights on just one frame.( change the kernel )

Hi,

You could refer the below documentation to add new kernels.

TIOVX User Guide: User Kernels and User Target Kernels

You could also refer the TIOVX/tutorial/ch03_graph to create a target kernel on C7 DSP

In the example whats difference with app_c7x_target_kernel_img_add.cpp and app_c7x_kernel_img_add.c

The .cpp is the target side implementation of the kernel (i.e. the code runs on C7x) and the .c is the host side implementation of the kernel (i.e. code runs on A72)
