【摘要】 RS码已经广泛地应用于通信系统、数字电视和计算机存储系统中,用来提高数据可靠性。以数字电视广播(DVB)标准中定义的RS(204,188)译码器为例,详细介绍了改进的欧几里德(ME)算法及以此算法为基础的RS译码器的超大规模集成电路VLSI实现,采用了流水线结构,对译码器的各个模块进行了分析和建模。通过对流程的仿真和综合验证,发现这些模块能较好的满足设计要求,能纠正不大于8个的误码。更多还原

【Abstract】 Reed-Solomon code has been widely used in communication systems, digital television and computer storage systems to enhance data reliability. This paper takes the Reed-Solomon (204,188) decoder which is defi ned in DVB standard for an example. The Modifi ed Euclidean (ME) algorithm and the VLSI implemented of Reed-Solomon decoder based on the algorithm are described in detail. The structure of decoder is pipeline. Modeling and analyzing some modules of the Reed-Solomon decoder. These modules afford satisfaction to the needs of the design and can correct the error codes less than 8 through the simulation and synthesis.更多还原
