摘要: Handling of the complexity which arises due the irregularity data nature for MPEG-4 object based video coding is an important issue in MPEG-4 texture decoder design. Another crucial issue is designing an efficient architecture to satisfy the resource sensitive nature of portable embedded video codec systems. This paper presents an architecture for texture decoding to address these two major issues. By adopting zero-skipping and zero index tables together, the throughput and power consumption are improved significantly. To avoid incurring extra hardware overhead, multiplication sharing and buffer sharing are also incorporated. ne synthesized design can perform texture decoding of CIF@30FPS under 2.18 MHz. using UMC 0.181 mu m 1P6M technology, the reported power consumption is 0.92 mW.
