The project of developing the core comes from a national key program in science and technologies , study on mcu high level language description and embeded system technology . the project is followed the top - down design way 这个项目遵循了自上而下的设计流程，从系统划分、编写代码、 rtl仿真、综合、门级仿真，到布局布线、电气规则检查、设计规则检查，网表比较等。
The concepts and philosophy of multithreaded programming technology are presented in this paper , and an example about scheduled - flight rules check - up in scheduled flight optimization system is given to explain the multithreaded programming method 分析了线程和多线程程序设计的概念和基本思想，并结合在航班优化系统中航班规则检查的应用实例，说明了多线程程序设计的实现方法。
Typical current - mode continuous - time filters include current - mode filter based on current conveyor , current - mode filter based on ota - c and current - mode filter based on current mirrors . they are rapidly developed in bandwidth , speed , precision , etc , and they bring the filter theories to noble times of fully integrated system development . there are many articles on continuous - time filter based on ota in nearly two years 在对版图设计的步骤、方法、所用软件以及cmos基础和工艺流程这些版图设计所需的基本理论研究的基础上,给出了本设计中用到的电容和nmos及pmos管版图结构,得到了具体ota - c滤波器版图,并对版图进行了几何设计规则检查和版图验证。
Base on above reason , this paper design and realize a c code rule compiler rulec engine . it can inspect the c code as the traditional compiler , besides that , it also include below functions : when this tool discovers the grammar error , it doesn ’ t stop the inspection and go on to inspect the left code ; the rules used in the inspection can increase , delete or amend according to user ’ s request . this tool can be runned on the windows , linux , solaris and other system platforms ; through counting the software complexity of c code , this tool can provide the important target of evaluated c code quality 因此,本文设计了一个c代码规则编译器rulecengine ,它除了实现与传统编译器一样能够检查c代码的功能,还实现了如下的功能:发现c代码语法错以后不停止检查,仍然继续对代码进行规则检查;检查c代码所需的规则可以根据用户的需求随意增加,删除或修改;能够在windows , solaris等系统平台上使用;通过统计c代码的软件复杂度,提供了衡量c代码质量的重要指标。
