| 摘 要： | 根据DSP的特点进行选型，选择了TMS320C6000系列的芯片作为图像压缩的硬件处理平台。利用CCS2．0仿真开发环境，对系统的软件进行了设计和仿真，实现了主要的编码运算和码率控制，并且利用DSP自带函数，根据图像压缩的特点进行了代码的优化，给出了软件总体流程和主要算法的框图，为代码的移植准备了条件。在硬件方面以DSP为核心处理器，设计发了基于DSP的图像处理平台，详细绘出原理电路图。最后将软件代码移植到硬件平台，并且进行了高压缩比的图像编码。探讨了基于DSP实现H263压缩编码的问题，指出了未来努力的方向。

| Abstract: | Considering the features of DSP, the chip of TMS C6000 is selected as the hardware platform for image compression. All of the software related is developed on the CCS2.0 environment. The basis and primary programme of coding and control is realized. Some optimization work is also done to reduce the processing time. The diagram of the algorithm is shown. Based on these work, the transplant of software from PC to DSP can be finished. The circuit serving the DSP is designed and the diagram is illustrated in detail. Finally, the software is planted successfully and the compression of the image is realized. The disagvantage of this method is discussed and some advice for future work is given. |
