摘要
提出了一种面积优化的RS(reed-solomon)解码器的设计方法.其运用一种改进的ME(Modified Euclide-an)算法求解关键方程模块,其它模块采用迭代结构.该方法减少了解码器中伽罗法域乘法器的使用,缩减了硬件规模.基于TSMC 90nm标准单元库的实现结果显示该文设计的解码器规模约为24000门,与同类设计相比规模最大可缩减36%.
This paper presents a new area-efficient implementation for Reed-solomon(RS)decoder.By using modified euclidean arithmetic to implement the equation solving circuits and the folding architecture for other modules,this method has decreased GF multipliers and simplify the hardware structure.Based on the TSMC 90nm standard cell library,the proposed RS decoder consists of about 24000gates,which is about 36%smaller than the same kind of conventional ones.
