i.MX53 VPU decoder output timing

Hi Chip experts,

I have a quesion when i.MX53 VPU decoded data write to the frame buffer.

Which timing is correct?

a) data wrote per each microblock decoded
b) or data wrote only when whole frame decoded

Thanks.

The VPU has an internal DSP called the BIT processor which controls the internal hardware blocks for

video decoder operations.

The BIT processor completes decoding operations on a frame-by-frame basis, which allows low level

independency of VPU operations to the host processor
