H.264/AVC significantly outperforms previous video coding standards with many new coding tools. However, the better performance comes at the price of the extraordinarily huge computational complexity and memory access requirement, which makes it difficult to design a hardwired encoder for realtime applications. In addition, due to the complex, sequential,(More)
This paper,presents an efficient VLSI architecture for the dehlocking filter in H.ZWIVT/AVC. We use an array of 8x4 &bit shift registers with reconligurable data path to support both horizontal filtering and vertical filtering on the same circuit (a parallel-in parallel-out reconfigurable FIR filter). Two SRAM modules are carefully organized not only for(More)
An H.264/AVC encoder [1] saves 25% to 45% and 50% to 70% of bit rates when compared with MPEG4 and MPEG2, respectively. New features include /4-pixel motion estimation (ME) with multiple reference frames (MRF) and variable block sizes (VBS), intra prediction, context-based adaptive variable length coding, deblocking, rate-distortion optimized mode decision,(More)
The most critical issue of an H.264/AVC decoder is the system architecture design with balanced pipelining schedules and proper degrees of parallelism. In this paper, a hybrid task pipelining scheme is first presented to greatly reduce the internal memory size and bandwidth. Block-level, macroblocklevel, and macroblock/frame-level pipelining schedules are(More)
