【摘要】 为了解决由于大量数据频繁读写而影响系统性能的问题,在分析了应用程序各部分处理时间的基础上,介绍了一种基于Altera NiosⅡ嵌入式处理器的智能相机系统(Smart Camera System)。采用C2H(C语言转换至硬件加速,C-to-Hardware)编译器生成硬件加速器的方法来加速数据的读取和存储。同时通过修改LAN91C111网卡的驱动程序,将图像数据即时发送至以太网。该方法对于在数据处理实时性要求较高的图像采集产品中应用,有很大的实用价值。更多还原

【Abstract】 In order to slove the problem that the system performance is influenced by frequent data reading and writing,this paper introduces a kind of smart camera system based on NiosⅡ embedded processor.This system uses C2H compiler to accelerate data reading and writing after analyzing the dealing time in application.At the same time,it sends graphic data to the net on time by amending the LAN91C111 device driver.This method has great practical value in the image collecting products that have high demand on data real time dealing.更多还原
