Recent two debug in DaVinci

1. DSP crashed after some ‘sin(), atan()’ … operations. All the operations are inside a loop with image size 320x240. Seems DaVinci cannot handle this case. It is no problem with loop size 320x240/4.
2. Data are shared between DSP and ARM. The output in ARM part are not correct (some are correct, some are random number or trimmed to 8-bit number only (0-255)). The pointer of outbuffer (outBufs) is wrong.
