大靶面拼接探测器的终端数据接收系统设计
Design of terminal data receiving system for large plane splicing detector
摘要
Abstract
With advances in large-area plane-splicing detector technology,it is essential that data process-ing terminals reliably receive large-scale,high-resolution image data at high speed and without errors.A terminal data-receiving system was developed,comprising a hardware device with two optical-fiber inter-faces,eight serial ports,and a PCI Express(PCIe)interface,together with a domestically developed de-vice driver.An FPGA serves as the system's central processing unit.This paper details the hardware ar-chitecture and several key technologies of the terminal data-receiving system,including optical-fiber data reception,data verification and buffering schemes,serial-port transmission control via the device driver,optimization of high-throughput data transfer between the hardware and host using scatter-gather DMA(SG-DMA),and the design of the domestic device driver.Experimental results indicate a sustained data-receiving rate of 2.26 GB/s,error-free continuous long-term operation,and a minimum driver response time of 111 μs.The terminal data-receiving system demonstrates excellent stability,throughput,and la-tency characteristics,evidencing strong performance and broad application potential.关键词
