According to the program structure of ansi c , some syntax - tree - nodes are designed in front - end , including function , block , data structure , type , expression , identifier and so on . syntax tree is divided into three levels , namely program level , function level and block level , which are useful for analysis of syntax and semantic in compiler as well as transferring syntax tree into rtl . retargetable compiler mainly includes intermediate representation , machine description and interface technique between compiler and machine description 编译前端的实现技术包括词法分析、语法语义分析和中间代码生成技术等,针对ansic的程序结构,分别设计了函数、块、数据结构、类型、表达式、标识符等语法树结点,并将语法树分成编译层次、函数声明和块三个不同层次,使语法树具有清晰的层次结构,有利于编译程序的语法和语义分析,以及从语法树到rtl中间表示的转换。
Also we describe the principle , architecture and the recent development tendency of the cmos is . after discussing the structures and characters of many micro image processing systems , we pay attention to the software of the system . research on the programming structures and programming methods are the key contents of the paper , including how to capture video based on vfw how to play video based on mci and how to process images based on dib 本论文针对基于cmos图像传感器的显微图像系统,详细论述了cmos图像传感器的原理、构造及当前的发展状况,阐述了各种显微图像处理系统的构成和特点,并着重针对基于cmos图像传感器的显微图像系统的软件处理问题研究了程序结构和编程方法,就如何使用基于vfw的视频捕捉,基于mci的视频播放,基于dib的图像操作等给出了应用结果。
The arrangement of this paper : the first chapter will simply introduce the development of the robot soccer and the generic robot soccer system and the enhanced one , and point out the research content of this paper ; the second chapter introduces the opinion net and how to use it to make the macro decision of attacking or defence ; the third chapter introduces optimize estimate technology accompanying with the opinion made in the previous chapter , to decide the lineup ; the fourth chapter introduces the general concepts of expert system and production system , point out how to construct the agent - based production robot soccer system integrated with opinion net and optimize estimate ; the at the last , give out the program structure and the simulation result 本文的内容安排如下:第一章,简介机器人足球的发展状况已经机器人足球系统的一般结构及改进结构,介绍了本课题的研究内容;第二章,讨论了机器人足球决策系统中的意向网络技术,并解释了如何利用意向网络来作出整体攻防决策;第三章,引入优度评价法,在上一章确立了整体攻防意向后,利用优度评价法进行进攻或防守队形的确定;第四章,介绍了专家系统及产生式专家子系统的一般概念,提出如何构建融合了意向网络及优度评价法的基于agent的产生式机器人足球系统。
In the first part , this paper analyzes the development of applying program structure and the limitation of 2 - tier c / s system structure . afterwards it introduces the concept , the system structure and the advantages of 3 - tier c / s system structure in detail . so this paper has some conducting function for those technocrats engaging in c / s research 本文第一部分首先分析了应用程序结构的发展过程以及两层c s体系结构的局限性,然后详细介绍了三层c s体系结构的概念、系统结构及其优势,所以本文对从事c s研究的技术人员有一定的指导作用。
Firstly , this paper discusses the working principle of the insulated monitoring device of rsj820 secondary ac circuit , and introduces the basic model structure of xc68hc912dg128 microcontrollers . secondly , it expatiates several evolution arithmetic of rapid speed and the several feasible schemes of software optimization in the nested real time system , and design a programming structure which use the multitask idea . at the same time , it brings forward the ideology of the software hiberarchy structure and the hardware modularization 本文首先论述了rsj820二次交流回路绝缘监测装置的工作原理;介绍了xc68hc912dg128微控制器的的基本模块结构;阐述了常用的几种快速开方算法和嵌入式实时系统软件优化的几种可行的方案;设计了在自动装置中使用多任务思想的一种程序结构;提出了自动装置开发中的软件层次结构和硬件模块化的思想方法;介绍了rsj820中使用的正弦波发生方案和采取的抗干扰措施;经过现场试运行,表明了rsj820达到了设计目的,能满足实际运行需要。
Second , in order to solve the practical problems , such as the problem that the computation for dynamic electromagnetic field costs a great deal of time and so does the drawing of electromagnetic field , the author establishes the reasonable program structure combined with advanced computer technology such as multi - thread in order to shorten computation time 其次,针对计算过程中的具体问题,同时由于处理动态电磁场计算并加以显示效果会消耗大量的时间,本文建立了合理的数据和程序结构,并结合多线程等较先进的处理技术来改进程序运行效果,建立任务调度模型。
