Hi there,
How to calculate the DDR Bandwidth in TDA3xx?
In document VisionSDk_DataSheet.pdf, section 9.6.3(DDR Bandwidth) says avg = 1209(MB/s) and peak = 2184(Mb/s) for TDA3xx.
Here we are running the demo usecase-f (video input :System Settings->Capture Settings->HDMI Capture 1080P60 (Not Supported in TDA2x/TDA2Ex Multi-serdes board)) and input video : Clip3.
Hence after video analysed, output is displayed on the screen. Using "p: Print Performance Statistics ", we are getting some statistics. In that, there are statistics named "Statistics Collector". i am referring it as DDR bandwidth (please correct me if i am wrong) for use-case 'f' Statistics Collector, are shown below.
Here the sum of Avg data(MB/s) = 2376(nearly), Peak data(Mb/s) = 5991(nearly), which is not nearly equal to the values mentioned in In document VisionSDk_DataSheet.pdf, section 9.6.3(DDR Bandwidth). PLEASE let me know how to calculate DDR bandwidth with reference to use-case-f in TDA3XX single camera usecases.
Thank you,
