Video encoding H.264/AVC CAVLC Pipeline architecture VLSI architecture for H.264 codec Entropy coding
Abstract—In this paper, we present an efficient hardware implementation of a Context
Adaptive Variable Length Coding (CAVLC) module for an H. 264/AVC video encoder. To
improve timing performance, a three-stage pipeline architecture is proposed including: input
data statistical analysis, encoding and packing. The context information and coding tables
are stored in memory elements. To minimize the hardware implementation overhead and
increase the system performance, in some subencoders, the codewords are calculated on ...
