H.264/AVC has been successful in the past 10 years owing to its wide use in many fields from high-definition digital TV (HDTV) to low-resolution one-segment mobile TV. In recent years, with the high demand for high-resolution applications, 4K resolution (UHDTV) which has four times the resolution of 1080p HDTV, has become highly required for video streaming and broadcasting. However, the computational complexity for 4K-resolution applications is still the bottleneck preventing the realization of real-time decoders. In this work, a motion vector management architecture that is designed for total motion vector management and calculation is proposed. The proposed architecture can calculate predicted motion vectors, select reference motion vectors for the direct mode, and calculate the motion vectors for interlace decoding. The proposed architecture can perform 176 cycles/MB decoding in the worst case. The simulation result shows that when working at 200 MHz, the proposed architecture can be implemented byabout 99k gates.
