摘　　要：首先分析了产生m序列的移位寄存器结构。在此基础上,针对复杂可编程器件的特点提出了一种可控长度、可控反馈系数的m序列设计方法;并在Quartus2.1开发软件环境下,采用复杂可编程器件EPM8282ALC84-2,实现了所提出的m序列的设计。其功能经过仿真验证,结果符合所设计的m序列要求。This article designed the maximal-length （ML） sequence generator with length and feeding-back under control based on complex programmable logical device （CPLD）. Firstly, it analyzed shift register configuration of ML sequence. Then, a new design about ML with length and feeding-back under control was proposed and fulfilled on the in-system programmable device, EPM8282ALC84-2 of ALTERA Company under the environment of Quartus2.1. Its function was tested and verified. The conclusion is consistent with the predicted ML. The system has easily characteristic of maintaining and expanding.
