# open-rknpu: Rockchip NPU task-program reconstruction

> open-rknpu reconstructs a task-program interface for the Rockchip RV1103/RV1106 NPU from board experiments and black-box comparisons. Its Python compiler emits register commands, weight and quantization blocks, and a container for bounded static ONNX convolution graphs; a C runtime submits them through /dev/rknpu. Research files document register and numerical findings.

## Requirements & limits

- **Prerequisites:** Host compilation needs Python, NumPy and ONNX; hardware runs need a compatible board and cross toolchain.
- **Prerequisites:** The reference board is a Luckfox Pico Mini B with the shared RV1106 NPU IP and driver v0.8.2.
- **Scope:** Dynamic shapes, LSTM/GRU, 1-D convolution, MatMul/Gemm and multi-stage detection heads are outside the documented scope.
- **License:** MIT license for the compiler, runtime, tests, examples and documentation.
