DM8217: Copying frames from shared to A8 memory takes too long

Zev Ovnat
Prodigy 175 points

Copying 1920 x 1080 YUV240SP frames (intercepted by means of

Vcam_getFullVideoFrames()) from shared to A8 malloc'ed memory takes 90ms per frame!!!

This seems wrong.

How can I reduce this? Caching? DMA transfer?

Please provide a code sample...

 

Thnx - Zev
