埠級通信 的英文怎麼說
中文拼音 [bùjítōngxìn]
埠級通信
英文
port level communication-
Secondly, a network based on multi - terminal components modeling methodology was applied to model mems at system - level by the analogy and mixed - signal modeling tool of vhdl - ams, for the system - level model of mems is a mixed signal model, which has attributes of multi - energy domains coupling, multi - signals mixed and interacting between discrete - event subsystems and continuous - time subsystems. with this method, the whole system can be divided into some subsystems defined as multi - terminal components ; the behavior of the subsystems depends only on their terminal signals ; the information exchange between subsystems was done by the signals at their terminals. the continuous - time systems or discrete - event systems can be modeled and simulated with this method, which satisfied the requirements of nonlinear systems and large signals analysis
同時，針對mems的系統級模型是一個混合信號模型，具有多能量域耦合、多信號混合、離散事件子系統與連續時間子系統交互的特點，使用vhdl - ams作為混合信號模型建模的工具，採用多埠組件網路建模方法建立了mems系統級模型，把微型機電系統分解為多個子系統或組件，各子系統被定義為多埠組件，子系統的內部行為通過其埠行為來描述，子系統間的能量與信號的交換通過組件的埠映射來實現，從而實現了對連續時間系統和離散事件系統的建模與模擬，滿足了非線性系統以及大信號分析要求。This article uses cpld technology to improve the hardware integration degree so as to ensure the high system reliability ; it applies digital signal process technology to producing and recognizing large volume ditigal voice signals in switch systems ; it replaces the old - used special voice signal process chips, thus lowers the cost, improves the quality ; it uses high quality common pc 104 units to complete the main processor tasks, which greatly improves the signal processing capability in the digital switch systems, and provides a great convinence for future technology upgrade as well ; in system archtecture, we exploit modular design technique on client ports and repeater ports, which gains more reliability and easy maintenance
本文主要採用了cpld技術提高硬體的集成度以保證系統的高可靠性：用數字信號處理技術完成交換系統中大量的語音信號的產生和識別，代替以前的專用語音信號處理晶元，降低了成本，提高了性能：用高性能的通用pc104單元完成主處理機的工作，大大提高了數字交換系統的信息處理能力，並為今後的技術升級提供了方便：在系統結構上對用戶埠和中繼埠採用模塊化設計，性能可靠，維護方便。When the egg - reached signal is sent to pc, through i / o card, the pc drives the video card to capture one frame picture to ram. after a series of mathematical analysis, the pc send the yolk color ' s or egg size ' s grading signals to outer signal delayed controller by i / o card again. last, the controller sends the delayed signals to outer execute equipment to finish classifying
蛋已到達光室的控制信號由數字量i o卡輸入到計算機；計算機通過對埠的查詢獲知這一信號后立刻驅動圖像採集卡將當前光室中的一幀圖像採集到主機內存中，進行相應的計算分析后將光室中鴨蛋蛋芯顏色或大小分級信號再經由數字量輸入輸出卡，送至外部信號延時控制器；控制器將此信號延時後送至外部執行機構，完成分級動作。In order to improve the efficiency of transmission, receiving ts data packet on cpu ' s gpio port and transmitting data on cpu ' s pci port are processed in different priority. to improve the communications efficiency, we adopt the multicast to deliver the digital tv to relevant user
在軟體的具體實現上採用了vxworks的多任務編程思想，為了提高傳輸效率，對在cpu的gpio埠的ts數據包的接收任務和在cpu的pci埠的數據發送任務分為不同的優先級處理，並且為了提高通信效率，我們採用組播的方式傳輸數字電視信號到相應的用戶。分享友人
