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 編譯前端的實現技術包括詞法分析、語法語義分析和中間代碼生成技術等,針對ansic的程序結構,分別設計了函數、塊、數據結構、類型、表達式、標識符等語法樹結點,并將語法樹分成編譯層次、函數聲明和塊三個不同層次,使語法樹具有清晰的層次結構,有利于編譯程序的語法和語義分析,以及從語法樹到rtl中間表示的轉換。
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 本論文針對基于cmos圖像傳感器的顯微圖像系統,詳細論述了cmos圖像傳感器的原理、構造及當前的發展狀況,闡述了各種顯微圖像處理系統的構成和特點,并著重針對基于cmos圖像傳感器的顯微圖像系統的軟件處理問題研究了程序結構和編程方法,就如何使用基于vfw的視頻捕捉,基于mci的視頻播放,基于dib的圖像操作等給出了應用結果。
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 本文的內容安排如下:第一章,簡介機器人足球的發展狀況已經機器人足球系統的一般結構及改進結構,介紹了本課題的研究內容;第二章,討論了機器人足球決策系統中的意向網絡技術,并解釋了如何利用意向網絡來作出整體攻防決策;第三章,引入優度評價法,在上一章確立了整體攻防意向后,利用優度評價法進行進攻或防守隊形的確定;第四章,介紹了專家系統及產生式專家子系統的一般概念,提出如何構建融合了意向網絡及優度評價法的基于agent的產生式機器人足球系統。
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應用程序結構的發展過程以及兩層c s體系結構的局限性,然后詳細介紹了三層c s體系結構的概念、系統結構及其優勢,所以本文對從事c s研究的技術人員有一定的指導作用。
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 本文首先論述了rsj820二次交流回路絕緣監測裝置的工作原理;介紹了xc68hc912dg128微控制器的的基本模塊結構;闡述了常用的幾種快速開方算法和嵌入式實時系統軟件優化的幾種可行的方案;設計了在自動裝置中使用多任務思想的一種程序結構;提出了自動裝置開發中的軟件層次結構和硬件模塊化的思想方法;介紹了rsj820中使用的正弦波發生方案和采取的抗干擾措施;經過現場試運行,表明了rsj820達到了設計目的,能滿足實際運行需要。
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,針對計算過程中的具體問題,同時由于處理動態電磁場計算并加以顯示效果會消耗大量的時間,本文建立了合理的數據和程序結構,并結合多線程等較先進的處理技術來改進程序運行效果,建立任務調度模型。
