11. Datasheet (Optiflow)

1. FPS : Effective framerate at which the application runs

2. Total time : Average time taken to process each frame, which includes pre-processing, inference and post-processing time

3. Inference time : Average time taken to infer each frame

4. CPU loading : Loading on different CPU cores present

5. DDR BW : DDR read and write BW used

6. HWA Loading : Loading on different Hardware accelerators present
