Abstract:
1. A method of a scalable fractional motion estimation (FME) for a multimedia coding system, comprising the steps of: (a) processing an H.264 coding to obtain a quality scalability of three quality levels and processing a scalable FME to said three quality levels; and (b) processing a block size trend prediction FME (BSTP-FME) to estimate required area and parallelism through one or more search ranges and obtaining a best selection according to signal-to-noise ratio (SNR) drop wherein said BSTP-FME comprises: controlling mode flow by receiving integer motion vectors (IMVs) to decide a flow for said IMVs; calculating motion vectors (MVs) by receiving said IMVs and processing motion estimations to corresponding fractional pixels to obtain MV costs; dual-directionally processing rotation interpolations to a plurality of the IMVs to obtain calculation data; calculating a sum-of-absolute-transformed-differences (SATD) by receiving said calculation data and obtaining SATDs of said corresponding fractional pixels; and selecting cost by receiving said MV costs and said SATDs to be accumulated and compared to obtain a best parallelism of hardware processing.
