6  Slave mode development 

In slave mode, RK1808 AI compute stick is a general AI accelerator. Model and data 

after pre-processing are inputted into the Host side(model and data are transmitted through 

rknn toolkit), RK1808 AI compute stick completes inference, and sends result back to the 

Host side, the Host side does post-processing, display and other manipulations. 

Slave mode development overall flowchart: 

 

Slave mode data stream flowchart: 

 

In slave mode, we will provide python and C API for host programming. 

 

When use Python programming, you need install RKNN-Toolkit in the Host. RK1808 AI 

compute stick U disk directory have provided the RKNN-Toolkit installation package. 

The  detail  instruction  about  RKNN-Toolkit  please  refer  to
