CCD信号采集系统中PCI接口设计

PCI Interface Design of CCD Signal Acquisition System

针对高速CCD信号采集系统中数据传输量大的特点,介绍了一种简单易用的高速数据采集系统中的PCI总线接口解决方案,论文采用FPGA实现PCI总线接口和PCI用户逻辑,提高了系统的集成度和可移植性,使高速的A/D转换器有高速的总线与其相匹配,有效的解决了数据的实时高速传输问题,为信号的实时处理提供了方便。

According to the characteristic of high speed of the CCD signal acquisition system. This paper introduces the design of hardware about data sampling based on PCI. This design integrates PCI bus interface and PCI user logic into a FPGA chip, it enhances the imegration and migration of the system. So the high speed A/D converter will match the high speed bus. It solves the problem of real-time transferring and saving effectively. And it also brings convenience for real-time processing the signal.
