摘要
采用VHDL语言和图形输入设计方法 ,给出了用CPLD在远程多路数据采集系统中实现地址译码、串口扩展、模块测试、模数转换以及高位数据处理等功能的具体方法 ,同时简要介绍了远程多路数据采集系统的工作原理及软、硬件框架。
The VHDL language and graphic input design method are described firstly,and then the address deˉcode,serial expand,module test and high-bit data handling in the remote and multichannel data acquisition sysˉtem,which based on the CPLD,are given.Lastly,the system operational principle,the software and hardware frame are introduced briefly.
