BF609 Video performace

Hello,

We are using the BF609 with video input from CMOS Sensor and output to display.

Input clock is 74MHz, and frame rate is 30FPS.  we are using 16 BIT interface YCrCb;
Resolution is VGA, but it is binning of 1.2MP so data is coming to the DSP with relative long blanking on the lines and frame.

Output is also VGA, but 8 bit (8+8 YCrCb), and we work at Aproximatly 30MHz.

We use 3 video frames, each in differnet memeory block to improve performance.

Our problem is that is looks like with these settings, there are performance issues and data is being corrupted.

Are these setting reasonable for the processor?

Are there any other recommendations other than using differnet memory banks for input and output frames?

Thanks

Ofer
