RZ/A2M: Write new library for drp

Hello,

I am very new to Renesas RZ board (R7S921053), just using it for past one week. I am looking to use the drp functionality for some work unrelated to image analysis. Could you please help me with these two things?

• Where I can find the current drp library for image analysis? I want to see how the code is written.
• And any tutorial on how to write your own library?

Thanks a lot!
