摘要
Compared to the related art, where the time distance in horizontal direction is 2 Synchronization Intervals (SI) between 2 Processing Units which are processing neighboring MB rows, the current invention enables to reduce the distance from 2 SIs to 1 SI, which increases the start-up phase performance. This is reached by dividing the filter task into sub tasks and reordering the execution order of these sub tasks. The sub tasks include a vertical edge filter task and a horizontal edge filter task. Further, the synchronization is scheduled in between the vertical edge filter task and the horizontal edge filter task.
