Abstract :
VBSME is adopted in the MPEG-4 AVC/H.264 standard. In this paper, we proposed a new VLSI architecture for VBSME with FS and TSS algorithms to support two resolutions. The architecture can reuse the smaller blocks´ SADs to calculate 4.1 motion vectors of a 16 × 16 block in parallel. Our design was implemented with 0.25μm CMOS technology. Under a clock frequency of 150Mhz, the architecture allows the real-time processing of 352 × 288 (or 720 × 576) at 30fps with FS (or TSS) in a search range [-16, +15].
