get image sensor data 27MHz to rt, cpu usage near to 100% (sbrio 9642)

i am using sbrio 9642 to get image data, and send the data to the rt.  I havn't to deal the data, and get some quesitons.

the image sensor is 27mhz, and the data size is 1024*768*U16 per  frame. 30 frames one second.

In rt, the  rt fifo is so slow to read the rt fifo, and the  RT WRITE is time out.  ANd the cpu usage is near 100%

1. Can the sbrio 9642  affort the data size of image sensor ?

2.how to improve the speed of RT FIFO READ to catch up the RT FIFO WRITE?

3. i think the first loop consume much cpu usage, how to improve to decrease the cpu usage?

hope your help!
