采用共享RAM方式实现振动信号的同步采样

Adopt shared RAM method to imply the synchronous sampling of vibration signals

为了满足振动信号同步采样的要求,采用了CPLD和神经元芯片共享RAM的结构设计,充分利用了系统已有的资源,提高了系统的测量精度。测试结果证实了设计的可靠性。

To meet synchronous sampling of vibration signals,the paper adopts an design that CPLD(complex programmable logic device) and neuron chip share RAM(random access memory). The design makes full of used resource and improves the accuracy of measurement. Result test it's credibility.
