详细说明：用ADI DSP编写的指令汇编了整个插补功能（包括水平、垂直、交叉插补），结果正确，包含了非常完整的测试数据

本程序是在CCS开发环境下，基于DM642的加密实现。-procedures in the CCS development environment, the DM642 based encryption.

基于LMS的双向回波削除源码，不过回波幅度不要大于0.2,否则算法认为DOUBLE TALK DETECT。各位可修改此阀值，试试效果-based on the two-way LMS Echo slashing source, but not greater than the rate Echo 0.2, or that the algorithm** DOUBLE TALK. You can modify this threshold, try Effect

堪称一绝的“IO口扫键”法，非常实用，节约大量的IO空间-One can never " IO port scan button" method is very useful, save a lot of IO space
