| 摘 要： | 为达到缩短RS截短码译码延时的目的，对译码算法中钱搜索部分进行优化设计，采取对RS码中被截去部分不进行验根计算，而把截去部分的累乘结果存入ROM表中，在后续计算中直接查ROM表使用存储结果，这种节省搜索时间的方法，在整体上缩短了译码延时。

| Abstract: | An optimized design of Chien-Search is given for reducing the time delay of shortened RS code＇s decoding. Without calculating the result of the cut parts of RS code, but filling the result of the cut parts into ROM form, looking up ROM form and using their memory results in the follow-up computation, so it can consumedly save the method of searching time, and shorten the time delay. |
