Abstract

This paper presents an efficient motion compensation architecture for MPEG-4 advanced simple profile at level 5 (ASP@L5) streaming video standard. A novel local memory storage scheme for motion vector prediction is proposed in the paper. In this scheme, local memory for storing differential data of motion information in video packet layer is avoided, and total memory access bandwidth is reduced 1/3. The motion compensation unit is implemented using 0.25μm 1-poly 5-metal CMOS technology, which occupies a silicon area of 1.35×1.35 mm² and operates at 150MHz. Simulation result shows that it is capable of compensating AS profile sequences at ITU-601 resolution video in real time.
