摘　　要：介绍一种基于PCI的高速数据采集系统。该系统采用了采样年达100MHz的AD9054芯片和读写周期为10ns的FIFO芯片,并利用高速的ispLSI PLD芯片实现采样窗和其他逻辑控制电路。数据的传输使用了符合TIA/EIA-644标准的低电压差分信号技术。数据通过PCI接口存储到计算机硬盘中,该PCI接口是利用现场可编程门阵列FPGA芯片实现的。In this thesis, a PCI based high speed data acquisition system is introduced. The system use an AD90S4 chip with sampling rate of 100MHz and a FIFO chip with read/wite cycle of 10ns. High speed ispLSI PLD chip is utilized to realize the sampling window and other logic control circuit. Low Voltage Differential Singnaling technology conformed to TIA/EIA -644 standard is used to transform the data. The data is stored to computer disk via PCI interface, which is based on field programming gate array chip.
