基于复杂可编程逻辑器件(CPLD),采用格雷码计数器设计了多定标器的计数系统.格冒码计数器具有计效时只有-位计数位发生改变的特性,无论何时读取计数值都不会发生数据错误,这是二进制计数器无法做到的.软件仿真和硬件测试结果表明,采用格雷码计数器设计的多定标器实现了两个时间道之间没有死时间、无漏计数和无重复计数的设计要求.

The counting system is developed by using Gray counter based on CPLD (Complex Programmable Logic Device). Only one hit is changed when Cray counter is working, whenever the data is always accurate from Gray counter, while that appears a little error from Binary counter. Result of software simulation and testing shows that there is no dead time between ti...
