摘要: 提出一种H.264/AVC Baseline Profile硬件解码器设计方案。该方案采用分级流水线架构,并通过增加并行度、优化存储结构等方法来提高性能。实验结果表明,该解码器可在最低1.5 MHz的频率下,满足QCIF分辨率下30 fps的实时解码,适用于移动多媒体设备、手持电话等低功耗场合中。

Abstract: A H.264/AVC Baseline Profile decoder is presented. The decoder is based on a hybrid pipeline architecture. In addition, several optimizations such as increased parallelism and optimized memory structure are adopted to improve overall system performance. Simulation results show that the decoder requires only 1.5 MHz for QCIF 30 fps real time decoding. The proposed decoder is designed for low-power applications such as mobile multimedia devices and cell phone.

Key words: H.264/AVC standard, decoder, hybrid pipeline
