TDA4VEN-Q1: Add a node on the c7x core

TDA4VEN-Q1: How to use tivxImgPreProcNode in ven

Part Number: TDA4VEN-Q1

Hello
I want to use the built-in tivxImgPreProcNode of TI on the TDA4 VEN platform (to convert nv12 images into the required rgbtensor format), but I encountered an error when running the app, as shown in the figure. I understand that this node is currently running on the c66 core, but there is no such core on the VEN platform. If I want to use this node on VEN, how should I proceed

    Hi Zhang,

    app_tidl_seg demo is not yet supported on j722s, and the c6x preproc and postproc will not work on j722s. So instead of that we are migrating the preproc and postproc to the a53 (using arm neon).

    You can refer to app_tidl_od demo. a53 based preproc and postproc is available inside $(psdkra)/edgeai/edgeai-tiovx-kernels

    $(psdkra)/edgeai/edgeai-tiovx-kernels/target/armv8/vx_dl_pre_proc_armv8_target.c

    If you still want to use c7x, then you have to migrate the c6x code to c7x on your own effort,
