摘要
结合TI公司C64系列DSP芯片指令并行处理的特点,在自主开发的以TMS320DM642为核心的嵌入式MPEG-4视频监控平台上,通过对编码软件进行C语言级、线性汇编级的优化,实现了高效运行的MPEG-4算法,完成了系统对视频编码的实时性要求。
This paper presented the MPEG-4 algorithm optimization of embedded surveillance system based on TMS320D- M642 chip, which makes full use of parallel processing characteristic of TI C64 series.Some methods of C code, linear assembly code optimization were applied in the software optimization of MPEG-4 encoding, which implement efficient and real time video encoding based on TMS320DM642.
