AM62A7: Hardware Acceleration & VPAC Questions

Jackson Carmichael

Part Number: AM62A7

Hello,

I have the following two questions about the AM62A7:

  1. Is hardware acceleration supported for decoding MJEPG frames that are received from a USB camera?
  2. Can VPAC work on raw data from memory (rather than from a MIPI interface)? If camera data is coming from the USB camera in MJPEG format, can this be converted into Bayer encoding and be fed into VPAC?

Thank you!

    Hi Jackson,

    On AM62A, the Hardware accelerator is only for MJPEG Encoding. There is no hardware accelerator for decoding.

    For your second question: Yes you should be able to read data from memory instead of MIPI interface. But I fail to understand why would you want to convert a MJPEG format to Bayer? Instead what you could do is decode and send the NV12 format data to our LDC/MSC as the VISS part of the VPAC expects Bayer format, but LDC and MSC expect NV12. 

    Hope this helps

    Best Regards,

    Suren
