TDA4VM: Is there response time data for TDA4?

Part Number: TDA4VM
Other Parts Discussed in Thread: TDA2,

Hi Expert, 

My customer concern the delay time very much, especially they experience long delay time of TDA2. Any delay time performance of TDA4 and AM62A that can show to my customer ?

Thanks

Daniel

  • Hello Daniel,

    Can you explain which delay time performance you are referencing? Is there a particular module such as memory (e.g. DDR) or perhaps CPU performance numbers? So we can find the right person to reply.

  • Hello Erick,

    i'm the customer Daniel mentioned,

    we used 2 camera to detect object, such as car, person, bike,

    our usecase was changed from tidl_od,

    each ssd model(0.64GMACS) run on 2 EVEs,

    we used tda2sxbu with plus mode,

    ddr was configured as DDR3-1066 ,2 EMIF(256M+256M+256M+256M) ,

    the fps of alg_tidl_dsp link was 24~25

    the system average delay time we calculated was about 0.15s

    so when bike speed up to 10km/hr,

    the detection results rectangle will be behind the bike,


    now we want to know if we porting the whole usecase to tda4VM or AM62A,

    Will it still be the same situation?

    It means that the application of AI model detection, how much the basic delay time?

    BR, Jay

  • TDA 2x supported less than 0.25 TOPS only, The TDA4VM supports 8 TOPS, so the latency would be much better in these devices compared to TDA2x
