Circuit design for pulse parameter measurement with programmable logical device 用可編程器件實(shí)現(xiàn)脈沖參數(shù)測量電路
The operator can assign a physical device to a logical device name through this command , as described in the second chapter 正如在第二章里所描述的,操作員通過這個命令,能把一個物理設(shè)備分配。

The interpolate technology just like a " ruler " , the resolving power of the " ruler " affect that the sampling points are arrayed correctly on time axis , and is determined by the multiple of the double slope integral amplifier . so it is core in the whole project . the project apply the complicated program logical device ( cpld ) 內(nèi)插技術(shù)的應(yīng)用使得隨機(jī)采樣理論能夠得以實(shí)現(xiàn),內(nèi)插技術(shù)相當(dāng)于測量用的“尺子” , “尺子”最小分辨能力決定了最后采樣點(diǎn)重新在時間軸上位置排列的真實(shí)可靠程度,這里尺子的最小分辨能力是由雙斜率積分時間擴(kuò)展器放大倍數(shù)決定的,所以說該模擬充放電放大電路在整個方案中是個很關(guān)鍵的部分。
Based on the primitive system , a logical device coordinate and its normalization function were defined to enhance the ability of device - independent , an input - output hierarchy model of application system in distributed interactive simulation was proposed , and an instance of the model was listed based on com 在研究分析已有原語系統(tǒng)的基礎(chǔ)上,通過定義邏輯設(shè)備坐標(biāo)系及其中的歸一化函數(shù)強(qiáng)化了設(shè)備無關(guān)性,提出了一個分布式交互仿真應(yīng)用系統(tǒng)輸入輸出層次模型,并基于com技術(shù)對該模型進(jìn)行了具體實(shí)現(xiàn)。
In the design , we make use of two eda tools max + plus ii and protel99 . because of the using of complex programmable logical device ( cpld ) , we can keep untuched the original hard circuit in design and realization of counting card , so it inherited the advantage of its predecessor . in order to quantitatively analyze the performance of data acquisition system with fifo cache , we introduced the queueing theory to build mathematic model to test its quality 在設(shè)計中借助了max + plusii和protel99兩個eda設(shè)計軟件。由于采用了復(fù)雜可編程邏輯器件cpld ,使得在計數(shù)卡的設(shè)計和實(shí)現(xiàn)中不用更改原硬件電路,對原設(shè)計的優(yōu)點(diǎn)有很好的繼承。在驗證系統(tǒng)改進(jìn)性能時,引入排隊論建立了數(shù)學(xué)模型對系統(tǒng)的工作性能進(jìn)行定量分析,證明其達(dá)到了設(shè)計要求。
