摘要:

以FPGA为核心处理器,完成了中波热像仪输出红外图像的实时采集与存储系统设计。系统主要由USB固件程序、FPGA控制程序和上位机软件组成,通过对工作在Slave FIFO 模式下的USB2.0接口芯片CY7C68013A内部FIFO进行控制,实现了USB接口的高速数据传输。应用结果表明,该系统具有数据传输速度快、采集数据准确等特点。

关键词: USB2.0, FPGA, Slave FIFO, 红外图像

Abstract:

The high speed data transmission system is introduced for the collection and storage of infrared images from medium-wave infrared thermal imager in real-time based on the core processor FPGA.The system consists mainly of USB firmware program,FPGA control program and PC software.High speed data transmission on USB interface is accomplished by the control of on-chip FIFO in the USB2.0 CY7C68013A working in Slave FIFO mode.The experimental results indicate that the system is high in speed and accurate in transmission.

Key words: USB2.0;FPGA;Slave FIFO;infrared image
