The accession of a data buffer storage is a effective measure to improve the speed of the data acquisition 外加数据缓存器件是提高数据采集卡速度的一个重要措施。
After consideration of owlan system structure , owmip includes smooth handover , route optimization , buffer storage management , and secure authentication Owmip协议根据owlan的体系结构,引入平滑切换、缓存管理、路由优化和安全认证的思想。
With regard to the buffer storage of the module , a new method called two - lever buffer structure is adopted , in which the fpga ‘ s internal ram cells is the first level buffer and the sdram of embedded system is the second level buffer 2 .在设备的缓存方案上采用二级缓冲结构,利用fpga内部提供的存储器单元作为第一级缓冲,利用嵌入式系统中的sdram作为第二级缓冲,实现了多通道、大规模缓存技术。
The framework generalizes the necessary steps of common radar processing , and solves the key problems of data registration , double - buffer storage , besides the data competition arbitration , and provides the ability of built - in parallel computation 该程序框架概括了一般雷达处理流程的必要步骤,解决了数据注册技术、双缓存区存储技术和数据竞争仲裁等关键技术问题,提供了内建的雷达并行处理能力。
Therefore , the depth of buffer storage and the number of serial channels increase greatly . in order to to restrain the common mode interference , high - performance isolation electric supply and photo - electricity coupler are employed . the safe and high - speed communication is realized 为了抑制信号的共模干扰,本设备采用了光电隔离技术,使用了高性能的隔离电源和高速光电耦合器,实现了安全、高速的通讯。
In this paper , the streaming media technology applied to network video monitor system are researched on the basis of video streaming . the emphases are put on system design , video captures and play , and the design of network transmission module and relevant software development method . in fact , uality of service of the network has unstable characteristics , we have analyzed qos guarantee strategy in video streaming transmission on network , and presents a integrated qos guarantee scheme which based on data encapsulation , buffer storage technology and congestion control on network . this scheme do its best to avoid the big delay or congestion on network based on make full use of network bandwidth , which can guarantee the best qos of the video transmission 重点讨论了系统架构、视频捕获和播放、网络传输模块设计以及相关软件开发方法。同时,针对实际网络中存在的服务不稳定性特点,分析了视频流在网络传输过程中的qos保证技术,并在系统中提出了基于数据封装、缓存技术以及网络拥塞控制机制的综合qos解决方案。该方案使系统在充分利用网络带宽的情况下最大程度上避免出现大的延迟或拥塞,保证了视频传输的最佳服务质量。
There are several advanced functions in control system of fed driving based on fpga . the special al875 can support multi - display format from qvga 、 vga 、 svga to xga in the digital rgb graphics and video frequency . using vga interface and d / a conversion technology , it can monitor data signal and control signal real time . the control of buffer storage carry out seamless link by double frame memory refurbish . osd can control menu and text to adjust state by double display 完成的基于fpga的新型fed驱动控制系统具有几种先进的功能:采用专用于rgb图形/视频信号数字化的al875芯片,可以支持从qvga 、 vga 、 svga到xga的多种分辨率的显示格式;采用vga接口技术和d / a转换技术,用于实时监控整个系统中的图像数据信号和控制信号;采用乒乓刷新控制机制对缓存进行控制,实现数据读写操作的无缝连接;采用osd在屏显示单元,实现控制菜单、文本在屏幕上的叠加显示。
