Circuit design for pulse parameter measurement with programmable logical device 用可编程器件实现脉冲参数测量电路
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,操作员通过这个命令,能把一个物理设备分配。

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 ) 内插技术的应用使得随机采样理论能够得以实现,内插技术相当于测量用的“尺子” , “尺子”最小分辨能力决定了最后采样点重新在时间轴上位置排列的真实可靠程度,这里尺子的最小分辨能力是由双斜率积分时间扩展器放大倍数决定的,所以说该模拟充放电放大电路在整个方案中是个很关键的部分。
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 在研究分析已有原语系统的基础上,通过定义逻辑设备坐标系及其中的归一化函数强化了设备无关性,提出了一个分布式交互仿真应用系统输入输出层次模型,并基于com技术对该模型进行了具体实现。
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 在设计中借助了max + plusii和protel99两个eda设计软件。由于采用了复杂可编程逻辑器件cpld ,使得在计数卡的设计和实现中不用更改原硬件电路,对原设计的优点有很好的继承。在验证系统改进性能时,引入排队论建立了数学模型对系统的工作性能进行定量分析,证明其达到了设计要求。
