Abstract

In H.264/AVC and the variants, the coding of context-based adaptive variable length codes (CAVLC) is one of the demanding operations, particularly for high bitrates such as 100Mbps. This paper presents a novel architecture that exploits component-level parallelism and pipeline techniques capable of processing high-bitrate video data in a macroblock(MB)-level pipelined CODEC architecture. Additionally, some techniques for efficient CAVLC coding is presented because CAVLC is a dominant part of the syntax coding. The resulting architecture, merged in a MB-level pipelined CODEC system, is capable of coding up to 100Mbps bitstreams in real-time, thus, accommodating the real-time encoding of 1080p 60Hz video.
