Through this system , the user can regard this multi - computer of network as a super computer which has many cpus and many memorizers 通過該系統,用戶可以把通過網絡連接的多臺計算機看作一臺超級計算機,它有多個cpu和多個存儲器。
In order to apply the system ' s real - time , this design uses a kind of fifo data memorizer , idt7204 which need not address and the data ' s input and output are independent 為實現系統的實時性,本系統采用一種先進先出的數據存儲器id竹204 ,無須地址線,且數據的輸入和輸出是獨立分開的。
This text described to use an memorizer with some additional and necessary of controlling by the conversion electric circuit according to the dds principle in order to produce the principle of sine wave and carry out a method 摘要敘述了基于dds原理,用存儲器附加必要的控制和轉換電路可產生正弦波的原理和實現方法。
In the case of unexpected power - off incidents the main controlling chip can write ik byte words into a memorizer called at24c08 by i2c bus , thereforc the important parameters of the electric net period of time before the incident will be recorded 通過i ~ 2c總線主控芯片可將1k字節的數據寫入at24c08存儲器中,在掉電的情況下仍能保存一段時間內電網的重要運行參數。
This paper gives detailed discussion on the design and the implementation of the personal minitype electrocardiograph ' s main control board . it includes such a few circuit modules as mcu , memorizer , lcd control , touch panel control and so on 本論文對“個人微型心電圖儀”主控板上的主要電路模塊的設計思想及實現原理進行了較詳細的敘述與討論,包括微控制器、存儲器、液晶顯示與控制、觸摸屏控制等電路模塊。
This hardware system has fully utilized interface hpi of host computer and memory resource that dsp offers , realizes parallel structure of share memorizer mode skillfully , the whole system structure is succinct , the programming is convenient and flexible , the expanding can be strong 該硬件系統充分利用了dsp所提供的主機接口hpi和內存資源,巧妙地實現了共享存儲器方式的并行結構,整個系統結構簡潔,編程方便、靈活,可擴展性強。
In the paper , the system architecture of the edbms based on the ems memory is pinpointed . those pivotal techniques in the development of the system , including the physical memorizer management , query process , data synchronization and other technology are further discussed 在這個思想的指導下,本文重點考慮了基于內存的嵌入式數據庫管理系統的體系結構,采用了有效的物理存儲管理機制、查詢處理和數據同步技術,并對關鍵部分的實現方式進行了詳細討論。
Power transformer test is simulanted in test - room , try to prove that online measure of transformer test is feasible . the test results are satisfaction . in the end , there is software design : the instrumented - test - interface is developed ; location computer entering to sample state is the same time , and after the same " log time " , it stops the data sample note . every test signal data keeping in the data note memorizer is at the same time , so it realizes data synchronization collection . some blocking design in the process of software design can apply to the other software 文章的最后,針對變壓器試驗微機測試系統對電流、電壓、功率等變量數據采集的特殊要求,分析了同步誤差的產生原因,給出了同步軟件采樣的無差條件;建立了電壓電流有效值和平均功率測量誤差的數學模型,提供了減小測量誤差的措施;應用“同步軟件采樣技術” ,不需要增加采樣周期數,不需要硬件同步環節,較好地解決了同步誤差對測量精度的影響。
