The Preview Engine block in the DaVinci video processing sub-system (VPSS) provides some critical functions for image and video processing. These functions, if implemented in software, require a significant number of computations in terms of million instructions per second (MIPs). By offloading these functions, the valuable MIPs can be used for more differentiating tasks, such as video compression
