摘要
介绍了在实际教学中应用VHDL设计出一种能产生m序列数字信号的发生器.该序列发生器具有序列长度和反馈连接设置,能产生多种m序列波形的特点.在软件上采用Altera公司的MAX+plusⅡ,完成m序列发生器的软件设计及仿真工作.通过北京百科融创科技有限公司的RC-EDA-IV型系统的开发板以及Altera公司的max7000s中的EPM7128SLC84-15芯片进行硬件下载测试,用数字示波器观察生成的m序列波形,实现了主要技术指标中的各项要求.
The signal generator,which can produce m sequence digital signal,was desighed by using VHDL in teaching.This signal generator is characterized with set of sequence length and feedback and can generate several m sequence signals.To complete the software design and the simulation work of the m sequence code generator,the MAX＋plus Ⅱ software of Altera Corporation was applied.Finally the hard ware downloading was tested through using the RC-EDA-IV System development board which was produced by the Beijing baikerongchuang technical limited company and the Altera corporation＇s EPM7128SLC84-15 chip of max7000s.With the digital oscilloscope observation,the production profile of m sequence code can satisfy the function request of the major technical indicators.
