相对码编译码器的软硬件设计

根据统一安全框本文对相对码进行深入理解，并简要阐述了相对码编译码器的原理。通过C语言编译环境，实现了编译码器的软件设计：基于Quartusll9．0软件平台；对设计的编译码器的硬件电路进行波形仿真。经比较得出：由相对码原理得出的结果、软件设计结果及硬件设计结果三者是一致的，验证了编译码器的软硬件设计的正确性。最后，简要简述了相对码在实际中的应用。

Software and Hardware Design of Coder and Decoder of Relative Code

The theories of coder and decoder of relative code are described briefly by indepth understanding the relative code in this article. The software design of coder and decoder is achieved by C language compiler environment, and the hardware circuit designed coder and decoder carries out waveform simulation based on Quartus II 9.0 software platform. After compared： the three results derived from the theories of relative code, software design and hardware design are consistent, therefore, the correctness of software and hardware design is validated for the coder and decoder. Finally, the practice applications are described briefly for the relative code.
