TDA4VM: different delay time between board emulation and PC emulation

Part Number: TDA4VM

Hello Champs,

The result of yolov5_ti_lite on PC emulation is 13.565ms





The result of yolov5_ti_lite on board emulation is 9.700ms


Which cause the delay time difference between board emulation and PC emulation? Is it related to the accuaracy?

Thanks
Regards
Shine

    Hi,

    To benchmark any network we recommend to run the inference on Target EVM.

    The benchmark number reproduced through Host Emulation run are prone to other facts like, DDR latency/ register reads latencies etc 

    One can use them for reference but we highly recommend EVM inference for benchmarking the models.
