TDA3: VIP and CSI2 video data using ISS (ISP)

Part Number: TDA3

Is is possible to route video data from VIP through ISS (ISP), i.e. VIP->ISP->MEM or MEM->ISP->MEM?

Is it possible to add a CSI2 video stream and process both VIP and CSI2 using ISP in real time?

    Hi Ewald,

    MEM->ISP-MEM is possible and supported in VisionSDK. With this memory to memory operation, we can support video streams from both VIP & CSI2.

    What kind of FPS / Frame resolution / Data Format is to be processed. 

    The VisionSDK demo application demonstrates processing of 4 channels of 1280x720 @ 30 FPS by the ISP.

    Hi Ewald,

    It is not possible to pass VIP output to ISS directly without going through memory. So if It is required to use VIP, then the data flow will be
    VIP -> MEM -> ISP -> MEM

    Regarding ISP, as we discussed, it is difficult to run two pass wdr flow in ISP. We can use Linear mode or single pass ISP flow for both the channels.
