数字频率计的设计可以分为测量计数和显示。其测量的基本原理是计算一定时间内待测信号的脉冲个数，这就要求由分频器产生标准闸门时间信号，计数器记录脉冲个数，由控制器对闸门信号进行选择，并对计数器使能断进行同步控制。控制器根据闸门信号确定最佳量程。-The design of digital frequency meter can be divided into measurement and display count. The basic principle of its measurement is calculated under test signal within a certain period of time the number of pulses, which have a standard requirement by the divider gate time signal pulse counter records the number of signals from the controller to choose the gates and counters to make off synchronous control can be carried out.Controller based on the gate signal to determine the optimum range.

针对某些嵌入式系统中处理数据量大和速度要求高的特点, 在剖析了uCOS - Ⅱ内核工作原理的基础上, 提出一种应用于uCOS - Ⅱ中的大容量内存文件系统的实现方案1 该方案通过在内存中建立文件系统, 将临时数据有效组织于内存中, 既提高访问速度又节省外存空间-against certain embedded systems handle large data volume and speed of high-features in the analysis for uCOS-II core principle on the basis of An application for uCOS-II, a large memory capacity of the file system to achieve a program of the program in 1988 through the construction documents, data will be temporarily effective organization in memory, not only increase the rate of savings Disk Space
