摘要：随着各种航天器中逐渐采用纳米级集成电路来构建其电子系统，多位数据同时翻转的
问题日益凸显。多位翻转不能被目前在航天电子系统中常用的纠一检二海明码纠正。针对这
一问题，本文设计实现了基于 BCH（Bose, Ray-Chaudhuri, Hocquenghem）码的编解码电路。
10 经充分验证，该电路的逻辑功能正确，能够纠正 32 位数据中的 2 位以内的错误。

Abstract: Recently, more and more nanometer scale integrated circuits are used in aero space
electronic system, which are eazily affected by multiple bits upset, which can not be corrected by
20 SECDED Hamming code. In this paper, an error correct circuit is design and implemented base
on BCH code. By sufficient verifiction, the function of the circuit is right, which can correct 2
errors in 32 bit data.
