## RKNPU2
  RKNPU2 provides an advanced interface to access Rockchip NPU.

## Support Platform
  - RK3566/RK3568
  - RK3588/RK3588S
  - RV1103/RV1106

Note: The content of this project is not applicable to RK1808/RV1109/RV1126/RK3399Pro.
      The rknn model must be generated using RKNN Toolkit 2 instead of RKNN Toolkit.
