- Abstract
- Motion estimation (ME) is a computation intensive procedure in H.264. In ME for variable block sizes, an effective scan ordering method has been devised for early termination of absolute difference computation when the termination does not affect the performance. The new ME circuit with effective scan ordering can reduce the amount of computation by 70% compared to JM8.2 and by 30% compared to the disable approximation unit (DAU) approach.
