- W2000367177 abstract "In this paper, we describe a VLSI architecture of video decoder for AVS (Audio Video Coding Standard). The system architecture, as well as the design of major function-specific processing units (VAriable Length Decoder, Deblocking Filter), is discussed. Analyzing the architecture of decoder system and the feature of each processing unit, we develop a system controller combined the centralized and decentralized control scheme, which provides high efficient communication between the processing units and minimizes the size of interconnected buffers. A bus-arbitration algorithm named Token Ring algorithm is designed to control the allocation of the SDRAM bus. This algorithm can avoid the conflicts on bus and reduce the internal buffer size, and its control logic is simple. Our simulation shows that this architecture can meet the requirement of AVS Jizhun Profile@4.0 level real time decoding, without a high cost in hardware and clock rate. Moreover, some design idea in the AVS decoder can be expanded to H.264 because of the similarity between the two video coding standards." @default.
