摘要
为满足多传感器数据采集及分析和图像融合等系统对多通道数据采集、缓存与处理的需求,本文设计了基于现场可编程逻辑门阵列(Field Programmable Gate Array,FPGA)的多通道数据采集输入、数据优先级仲裁、SDRAM数据读写控制以及视频显示等模块,实现了多通道数据稳定采集、缓存与显示的功能。系统仿真测试结果表明,本系统数据读写准确,能够满足多通道数据高速、实时采集与缓存的功能。本系统采用模块化设计,通用性强、灵活性好,具有较高的工程应用价值。
In order to meet the requirements of multi-channel data acquisition, caching and processing in multi-sensor data acquisition and analysis and image fusion systems, this paper designs multi-channel data acquisition and input, data priority arbitration, SDRAM data read-write control and video display modules based on field programmable gate array(FPGA), The functions of stable multi-channel data acquisition, cache and display are realized. The system simulation test results show that the data reading and writing of the system is accurate, and can meet the functions of multi-channel data high-speed, real-time acquisition and cache. The system adopts modular design, has strong universality and good flexibility, and has high engineering application value.
