Jetson Nano's Tegra X1 Block Diagram

Hi, does anyone know if there is a block diagram of the Jetson Nano’s Tegra X1? I’ve found one for the mobile processor Tegra X1 (where two sets of ARM are shown, Cortex-A57 and A53, but as far as I am concerned the Jetson Nano only has the Cortex-A57).

Thanks for the help.

Only A57 is available on nano.
