摘要
FPGA由于集成了超大规模集成电路和可编程器件的诸多优点,其在现代工业生产和科学研究中的数据采集和处理的应用越来越广泛。本文针对SSI接口类传感器数据采集与数理需求,设计了以FPGA为核心处理器的多通道数据采集系统。所设计的系统通过PCI9054桥接芯片实现FPGA局部总线到PMC/PCI总线的转换,而后再通过PMC/PCI总线完成数据采集系统与上层母板的连接和通讯。系统调试结果表明所设计的系统能够实现数据采集处理功能。
Because of the many advantages of FPGA integrated and programmable VLSI devices , its data acquisition and processing applications in modern industrial production and scientific research more widely. Aiming SSI interface class sensor data acquisition and mathematical needs, design the FPGA as the core processor, multi-channel data acquisition system. In this paper, a system designed to achieve local bus FPGA PMC / conversion by PCI9054 PCI bus bridge chip , and then through the PMC/PCI bus complete the data acquisition system and the upper motherboard connection and communication. System debugging results show that the designed system can achieve data acquisition and processing functions.
