【摘要】 介绍了一种利用标准VHDL(硬件描述语言)编写驱动程序的光信号采集系统的实现方法,给出了采用这种方法设计的电路框图,并给出了该设计的CPLD(复杂可编程逻辑器件)实现方法,最后用VHDL语言和QuartusⅡ开发软件进行了仿真验证。结果表明该方法十分简便,电路结构简单,成本低,实用性好。更多还原

【Abstract】 In this paper,we introduce a new realization method in design of data gathering system which uses VHDL(one kind of standard hardware description language) to compile the drive program.According to the new design method,the block diagram of the new data acquisition system is presented,and the design of CPLD device is discussed.Finally,simulated verification is made using VHDL language and the software of QuartusⅡ.Results show that the new method can simplify the design ,reduce cost and has good practical usability.更多还原
