摘要
设计了一种基于FPGA的图像采集卡,集合了目前流行的高速光纤技术和PCI Express总线,并运用分层的Aurora协议和PCI Express协议实现光纤和PCI-E总线上数据的管理。在FPGA算法设计中,提出“预转换”策略和“双阈值”策略来管理和优化跨越高速光纤模块和PCI Express模块的高速数据传输过程。在实验中,数据传输达到了预期的高速实时传输的目标。
Abstract
A design of image acquisition card based on FPGA is presented, in which high-speed fiber-optic and PCI Express bus technology are integrated, and multi-layered protocols of PCI Express and Aurora protocol are applied for data management on the fiber and PCI Express bus. Algorithms in the FPGA use "pre-conversion" and "double threshold" strategies to manage and optimize the data processes across high-speed fiber modules and PCI Express module. The experiments show that it achieves good real-time transfer performance as expected.
