【摘要】 本文结合TI公司的TMS320DM642的结构特点和H.264视频压缩标准的要求,提出了两种H.264编码器在TMS320DM642上的存储空间优化方案:一是程序数据全部放置到片外SDRAM,二是频繁调用的数据和核心程序放置进片内SRAM,并实现和比较了这两种方案。经过存储空间优化后,编码器每秒可编码23-25帧QCIF格式图像。更多还原

【Abstract】 This thesis described two different storage optimization strategies based on the H.264 video compression standards and Texas Instruments’ TMS320DM642 Digital Media Processor hardware architecture. In the first project, all data and programs were placed outside SDRAM, and in another, data used in a high frequency and core program were placed inside SRAM. It also realized these two projects and compared them. The H.264 encoder can provide 23~25 frames per second encoding performance for QCIF resolution video.更多还原
