摘　　要：针对基于线阵电荷耦合元件(CCD)成像原理的调焦调平系统强实时性、高同步性及高数据率的特点,设计了一种基于串行RapidIO总线协议的光纤通信测试系统。该系统以现场可编程门阵列(FPGA)为控制核心,以光纤为传输介质,通过串行RapidIO总线协议完成对调焦调平系统性能验证过程中的指令控制和图像数据传输。基于双存储器(FIFO)缓冲的SRIO接口设计使得该测试系统具有较强的通用性和实用性。测试结果表明,该系统光纤接口数据传输速率达440 MB/s,能够满足调焦调平系统性能验证对数据传输速率及正确性的需求。Aiming at the characteristics of strong real-time,high synchronization and high data rate of the focusing and leveling system based on the linear Charge-coupled Device(CCD)imaging principle,an optical fiber communication test system based on the serial RapidIO bus protocol was designed.The system uses Field-Programmable Gate Array(FPGA)as the control core,optical fiber as the transmission medium,and completes the command control and image data transmission during the performance verification process of the focusing and leveling system through the serial RapidIO bus protocol.The SRIO interface design based on dual First Input First Output(FIFO)buffers makes the test system highly versatile and practical.The test results show that the data transmission rate of the optical fiber interface of the system reaches 440 MB/s,which can meet the requirements of data transmission rate and correctness for the performance verification of the focusing and leveling system.
