Abstract
Video and image compression standards, such as MPEG-1/2/4, H.264, and VC-1, are widely used in video and imageapplications. In this thesis, the proposed low cost highthroughput architecture for multi-standard transform using common sharing distributed arithmetic (CSDA) can support variable video compression standards. Moreover, the proposedarchitecture can process four transform types including 8 × 8, 4 × 4, 4 × 8,and 8 × 4 transforms. In this thesis, the proposed CSDA strategy can increase the circuit sharing capability among the coecients and reduce the number of adders in adder tree. Hence, the proposed architecture can be implemented by using less hardware cost. In data processing rate, the proposed architecture can process the eight pixel data per cycle and operates in 205MHz clock frequency. Therefore, the proposed two-dimensional (2-D) architecture can achieve 1.64G-pixels/s throughput rate with the hardware cost of 30K gates, and the throughput rate can meet the speci cations of digital cinema (4298 × 2048@24Hz) with 4:4:4 video processing bits and high de nition television (HDTV) 1080p(1920 × 1080@60Hz) with 4:2:0 video processing bits. For veri cation, the proposed 2-Darchitecture is implemented by using TSMC 0.18-m CMOS 1P6M process.
