TDA4AL-Q1: Which part of TDA4AL processes camera sensor images for auto white balance/auto exposure/auto focus?

Hello,

TI does not use C7x or C7_MMA for camera ISP and processing 3A on the TDA4AL; they are used primarily for TI Deep Learning features.

The TDA4AL camera and ISP functionality are handled by the Vision Processing Accelerators (VPAC).

Look at the datasheet --> TDA4VE TDA4AL TDA4VL Jacinto Processors, Silicon Revision 1.0 datasheet (Rev. B)

If you want an SDK release, we suggest you look at the https://www.ti.com/tool/download/PROCESSOR-SDK-RTOS-J721S2 documentation, which included Imaging chapter -->

Thanks.
