Kneron PLUS stands for Platform Library Unified Software which is a framework comprising new software(SW) and firmware(FW) design for KL520 (and alpha for KL720).

In order to run the inference of models on Kneron AI dongles, there are three parts of AI application development are required:

Below diagram depicts three parts of development in a big picture.

However, this document only focuses on the software development and the firmware development. For the model development, please refer to the Toolchain Docker part.

In comparison with the previous SW/FW framework, this aims to simplify the design flow for AI applications development.

Below gives some definitions regarding the Kneron PLUS:
