摘要
提出了一种新的将查找表法与同步块分组法相结合的8B/10B译码方案,整个系统包括特殊字符检测模块、6B/5B译码模块、4B/3B译码模块及标记输出模块4个模块。该系统除了能够正确译码外,还具有码字类型判断、误码组检测、偏差检错及误码替换等功能。整体译码方案用VHDL语言实现算法描述,并在QuartusⅡ软件平台上完成了电路综合和波形仿真。实验结果表明,该方案具有占用资源少、逻辑运算量小、译码速度快、实时性好、检错率高等优点。
This paper proposes a new 8B/10B decoding scheme that combines the look-up table method with the synchronous block grouping method.The whole system includes the special character detection module,the 6B/5B decoding module,the 4B/3B decoding module and the mark output module.In addition to correct decoding,the system also has functions such as code word type judgment,error group detection,deviation error detection and error code replacement.The overall decoding scheme uses VHDL language to realize the algorithm description and completes the circuit synthesis and waveform simulation on the QuartusⅡsoftware platform.The experimental results show that the scheme has the advantages of small resource occupation,small logic operation,fast decoding speed,good real-time performance and high error detection rate.
