## 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.

## ReleaseLog

### 1.3.0

- Support RV1103/RV1106（Beta SDK）
- rknn_tensor_attr support w_stride(rename from stride) and h_stride
- Rename rknn_destroy_mem()
- Support more NPU operators, such as Where, Resize, Pad, Reshape, Transpose etc.
- RK3588 support multi-batch multi-core mode
- When RKNN_LOG_LEVEL=4, it supports to display the MACs utilization and bandwidth occupation of each layer.
- Bug fix

### 1.2.0

- Support RK3588
- Support more operators, such as GRU、Swish、LayerNorm etc.

   - Support flashing cache for fd pointed to internal tensor memory which are allocated by users
   - Improve dumping internal layer results of the model
   - Add rknn_server application as proxy between PC and board
   - Support more operators, such as HardSigmoid、HardSwish、Gather、ReduceMax、Elu
   - Add LSTM support (structure cifg and peephole are not supported, function: layernormal, clip is not supported)
   - Bug fix

### 1.0
   - Optimize the performance of rknn_inputs_set()
   - Add more functions for zero-copy

   - Add new OP support, see OP support list document for details.
   - Bug fix

### 0.6
   - Initial version
