Parallel processing technique deals with many aspects . it includes hardware technique , parallel architectures , parallel operating system , parallel languages , parallel compiler , parallel software , parallel algorithm , etc . but the current international situation is that the development of parallel algorithm is far more behind other architectures . the most dominating appearances are the lacks of corresponding software , the rational distributing of tasks , the communications and the synchronization 虽然使用范围很广,但目前国内外的并行算法应用研究明显地滞后于其体系结构的发展,许多方面尚处于探索阶段,技术上还不是很成熟,其中最主要的表现就是配套软件的欠缺,任务合理分配的问题和通信与同步的问题。
Drawing machine i developed adopts embedded technology , implements control by 32 - bit microprocessor . this kind of drawing machine can draw itself without relevant software , not controlled by computer , and it also can display the graphics on the lcd screen . there are usb and network interface in the machine , we can draw a graphics from an usb disk or any computer on the internet 本课题采用嵌入式开发系统开发大型服装cad绘图机，用32位微处理器控制，使绘图机不受上位机的控制，自身就具有绘图功能，无需配套软件，而且能够在液晶屏上显示所画的图形；绘图机具有usb接口和网口，可以通过读u盘里的绘图文件直接绘图，也可以通过网口读局域网内任意一台计算机里的绘图文件进行绘图。
The thesis discussed the building processes and working principles of presented classifiers , and developed the corresponding software for color separation of dot images with the operation system of microsoft ? window * me and microsoft visual studio c + + 6 . 0 . in the end , some experiments were carried out to verify these classifiers and error analysis was given ; the next research direction was pointed out 课题对各种分类器的构建过程及工作原理进行了细致准确的论述，并以microsoftwindowme为操作平台采用microsoftvisualstudioc + + 6 . 0为工具开发出用于网点图像分色处理的dia系统配套软件，该软件同时还具有相应的图像处理功能。
