| 摘 要： | 针对高速数字核脉冲采集中的实时传输问题,提出了一种基于FPGA和USB的传输结构。该结构采用现场可编程逻辑阵列(FPGA)作为核心控制器,并通过乒乓操作原理对高速核脉冲进行采集,定义特定的简单可靠的传输帧结构。利用USB与PC机通信,既实现了高速数据的实时传输又真正实现了"即插即用",提高了整套系统的实用性。实验测试验证了该系统的高效性。

| Abstract: | It presents a FPGA and USB based transmission structure for the problem of high speed digital nuclear-pulse acquisition and real-time transmission.The structure uses field programmable logic array(FPGA) as the core controller,acquires high speed nuclear-pulse through the principle of ping-pong operation,and defines a specific simple and reliable transmission frame structure.It can communicate with PC through the USB interface,which enable it to achieve both high speed data real-time transmission and truly "plug and play",which improves the utility of the entire system.The efficiency of this system has been verified through experimental tests. |
