Fri Dec 14 00:58:55 PST 2012
FIMC is stand for Fully Interfactive Mobile Camera and
supports image scaler/rotator/crop/flip/csc and input/output DMA operations.
input DMA reads image data from the memory.
output DMA writes image data to memory.
FIMC supports image rotation and image effect functions.
also supports writeback and display output operations.
