摘要 研究了嵌入式系统中 H.264 Baseline 软件解码器设计和优化的问题,提出了四种有效的优化方法,并在 PXA270平台上进行了测试。测试结果显示,综合使用提出的四种方法,H.264软件解码器在 PXA270(520MHz)上运行时帧率可以达到22f/s(CIF 格式)和80f/s(QCIF 格式)。 This paper focuses on the problem of design and optimization of H.264 baseline software decoder on embedded system, it proposes four effective optimization methods, and performs tests on a PXA270 platform. The test results show that, by combined the optimization methods proposed in this paper, the H.264 software decoder can achieve the frame rate of 22fps(CIF) and 80fps (QCIF) respectively on PXA270(520MHz).
