    CX3: Any way to transfer 4K image data from DMA buffer to Host App through USB2.0 port without changing image quality?

    user_483423427

      Hello,

      We're using CX3 to transfer data from image sensor to Host app.

      Structure: Image sensor - CX3 - Host App (USB2.0 port)

      Image sensor: Raw 10, 4000 x 3000 x30fps -> streaming to CX3

      I/F: MIPI

      It's ok to drop the frame rate but image data should be received by Host App as it's quality (4000x3000)

      USB 2.0 bandwidth is low so we couldn't received the image by Host App (the DMA buffer seem to be overwritten)

       

      [Question] Any way to configure DMA buffer of CX3 to transfer this 4K image data to Host App through USB2.0 port without changing image quality?

       

      Regards,
