Design Of H.264/avc Decoder And Its Application In Soc

JVT(Joint Video Team) was founded in Pattaya, Thailand in Dec. 2001. It is made up of the video-coding experts in two international standard: ITU-T and ISO. The purpose of JVT's work is to establish a brand new video coding standard, in order to reach the goal of high compressing ratio, better image quality, and friendly network adaptability.Since the design of every practical application system is based on the theory, and then we should analyze and optimize; eventually we can get the best and the most practiced design. Meanwhile, with the development of video coding and LSI design, people accumulated plenty of traditional method to process video data and lots of methodology to design circuit, which is essential to design this chip. Based on things above, we can complete the design flow such as system SW/HW partition, RTL coding & simulation, synthesis etc. At the same time, verification is important for a successful chip, therefore the paper describes the key verification used in the project. Finally, the result of system implementation is given out.This thesis covers pans of the front-end design flow of H.264/AVC decoder and it application in SoC, the design tasks that finished by me as follows are also introduced in detail:1. Doing relative H.264 bitstream processing, remove data that is unrelative to the decoding. That's the design of bitstream header changing module.2. Providing appropriate data to the three entropy decoder, that is design of the bitstream controlling module: Input buffer controller.3. In the process of deblocking, the design of pre-deblocking hardware accelerator module.4. In charge of verification to the modules above and system SW/HW debug。...
