The accession of a data buffer storage is a effective measure to improve the speed of the data acquisition 外加數據緩存器件是提高數據采集卡速度的一個重要措施。
After consideration of owlan system structure , owmip includes smooth handover , route optimization , buffer storage management , and secure authentication Owmip協議根據owlan的體系結構,引入平滑切換、緩存管理、路由優(yōu)化和安全認證的思想。
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 .在設備的緩存方案上采用二級緩沖結構,利用fpga內部提供的存儲器單元作為第一級緩沖,利用嵌入式系統(tǒng)中的sdram作為第二級緩沖,實現了多通道、大規(guī)模緩存技術。
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 該程序框架概括了一般雷達處理流程的必要步驟,解決了數據注冊技術、雙緩存區(qū)存儲技術和數據競爭仲裁等關鍵技術問題,提供了內建的雷達并行處理能力。
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 為了抑制信號的共模干擾,本設備采用了光電隔離技術,使用了高性能的隔離電源和高速光電耦合器,實現了安全、高速的通訊。
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 重點討論了系統(tǒng)架構、視頻捕獲和播放、網絡傳輸模塊設計以及相關軟件開發(fā)方法。同時,針對實際網絡中存在的服務不穩(wěn)定性特點,分析了視頻流在網絡傳輸過程中的qos保證技術,并在系統(tǒng)中提出了基于數據封裝、緩存技術以及網絡擁塞控制機制的綜合qos解決方案。該方案使系統(tǒng)在充分利用網絡帶寬的情況下最大程度上避免出現大的延遲或擁塞,保證了視頻傳輸的最佳服務質量。
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驅動控制系統(tǒng)具有幾種先進的功能:采用專用于rgb圖形/視頻信號數字化的al875芯片,可以支持從qvga 、 vga 、 svga到xga的多種分辨率的顯示格式;采用vga接口技術和d / a轉換技術,用于實時監(jiān)控整個系統(tǒng)中的圖像數據信號和控制信號;采用乒乓刷新控制機制對緩存進行控制,實現數據讀寫操作的無縫連接;采用osd在屏顯示單元,實現控制菜單、文本在屏幕上的疊加顯示。
