PMD自适应补偿控制模块自启动的实现

The realization of PMD adaptive compensation control module self-starting

为解决偏振模色散自适应补偿控制模块的自启动问题,提出了一种使用ROM引导、完全利用C语言进行程序烧写的自启动方案。首先分析了该模块的自启动过程,其次进行了自启动的硬件接口设计,最后重点介绍了自启动的C语言编程过程,给出了自启动的C语言源程序、cmd文件和Fl ash烧写流程图。

To solve the self-starting problem of adaptive polarization mode dispersion compensation control module,a scheme is presented which uses Rom boot mode and fully adopts C language to program Flash.Firstly,the self-starting process of the module is analyzed.And then the hardware interface of the self-starting is designed.At last,the paper emphatically introduces the C language programming process of the self-starting;also it shows the self-starting C language source code,the link command file and Flash programming flow chart.
