摘要
针对图像处理系统灵活性不足与智能化水平待提升的问题,本研究致力于克服国产FPGA动态重构领域存在的技术瓶颈,提出了一个逻辑层动态调度图像系统。该系统基于上海安路科技公司PH1A90 FPGA芯片与Qt框架进行开发,基于逻辑层动态调度原理通过智能上位机控制模块可实现近似于DPR的全链路动态调度行为。实验结果表明,本研究实现了Qt上位机与PH1A90 FPGA的软硬件协同,完成了四接口异构输入、双传感器协同成像、算法处理链配置与22种ISP动态处理算法,并通过HDMI输出1080P@60 fps视频流,验证了接口、流程以及算法上的逻辑层动态调度能力与国产芯片的工业级可靠性,推动我国智能安防、工业检测等领域的自主可控进程。
In response to the limitations in flexibility and the insufficient level of intelligence in existing image processing systems,this study addresses key technical challenges in the dynamic reconfiguration domain of domestic FPGAs by proposing a logic-level dynamically scheduled image processing system.The system is developed based on the PH1A90 FPGA chip from Shanghai Anlogic Technology Co.,Ltd.,integrated with a Qt-based host platform.By employing logic-level dynamic scheduling principles,the system achieves near-Dynamic Partial Reconfiguration(DPR)-level full-link dynamic scheduling under the control of an intelligent host module.Experimental validation demonstrates successful hardware-software co-design between the Qt host and the PH1A90 FPGA,achieving four-interface heterogeneous data acquisition,dual-sensor collaborative imaging,dynamic configuration of algorithmic processing chains,and real-time execution of twenty-two dynamic ISP algorithms.The system outputs 1080P@60 fps video streams via HDMI,validating its dynamic scheduling capabilities across interfaces,workflows,and algorithms at the logic level.Furthermore,the results confirm the industrial-grade reliability of domestic FPGA solutions,contributing to the advancement of independent and controllable technologies in fields such as intelligent security and industrial inspection.
