Abstract
A video encoder is disclosed. The video encoder comprises an integer level motion estimation hardware component configured to determine candidate integer level motion vectors for a video being encoded. The video encoder comprises a fractional motion estimation hardware component configured to receive the candidate integer level motion vectors from the integer level motion estimation hardware component and refine the candidate integer level motion vectors into candidate sub-pixel level motion vectors. The fractional motion estimation hardware component includes parallel pipelines configured to process coding units of a frame of the video in parallel across the parallel pipelines.
