在设计上除模拟控制及总线驱动等器件外，尽量采用FPGA来实现控制逻辑以提供应用平台的可扩展性。

Except for the analogue controlling and bus driving devices, we use FPGA to implement controlling logic in order to provide expansibility of application platform.

为此，本文设计了一款基于PCI总线且具备可扩展大容量存储设备接口的高速模拟信号采集卡，将高速数据采集和大容量实时存储结合在一起。

This high-speed data acquisition card designed is based on PCI bus and have high capacity memory interface. It combines high-speed date acquisition and high capacity real-time memory.
