电磁的放射将在信息结果当计算机工作时,漏正在被恢复。这篇文章基于外部部件介绍一个高速度的即时数据获得系统相连(一种总线标准) 总线和域电磁的放射由录像信号引起了的可编程的门数组(FPGA ) fors ampling。硬件设计和每个模块的控制流动详细被介绍。64 Msps 和系统转移加速的采样率罐头活动范围能直到由使用交叉的时间的 128 Mb/s,它由在平行操作二个数据变换器增加一个系统的全面采样速度。
The electromagnetic radiation will result in informa- tion leakage being recovered when computers work. This article presents a high-speed real-time data acquisition system based on peripheral component interconnect (PCI) bus and field programmable gate array (FPGA) for sampling electromagnetic radiation caused by video signal. The hardware design and controlling flow of each module are introduced in detail. The sampling rate can reach 64 Msps and system transfers speed can be up to 128 Mb/s by using time interleaving, which increases the overall sampling speed of a system by operating two data converters in parallel.
