最后，论文设计了基于浮点DSP TMS320C 6701的音频解码程序的IMDCT部分，经过测试可以做到实时的解码音频信号和系统控制。

Last, the thesis design the IMDCT software of AC-3 audio decoder based on float DSP TMS320C6701, the result is that TMS320C6701 can decode audio signal and control the system in real time.

如何设计一个新的编解码器的框架，使其能够方便的扩充新的编解码方式和支持新的类型描述语言，是当前使用TTCN - 3测试时迫切需要解决的问题。

So How to design a new codec framework, which can easily expand new codec method and also support to expand new type language, is the urgent task in current popularize of applying TTCN-3 to test.
