【摘要】 随着嵌入式实时系统VxWorks 在国内的广泛应用,基于VxWorks 平台的旧显示解决方案已经不能满足用户对该系统性能日益增长的要求。本课题正是为了解决这一问题,深入研究了基于VxWorks 系统新的显示解决方案——WindML,论证了新方案在技术上的重大优势,从WindML 的体系结构入手,以WindML 基本2D 显示方案为基础,通过对WindML 系统的系统原理,各种服务和管理的研究和学习,提出了基于VxWorks 系统的汉字解决方案,并通过对FreeType 2 字体引擎、矢量字体的研究,利用WindML 系统机制,完成了位图及矢量汉字在VxWorks 系统中的实现,在此基础上设计并优化了汉字输入法的查询算法,开发出了基于VxWorks 系统的汉字输入法。本课题第一次系统、完整的论述和实现了基于VxWorks 系统的WindML 显示解决方案,为VxWorks 系统开发者提供了开发汉字系统的中间件,为VxWorks 这一优秀的嵌入式实时系统在国内更广泛的应用提供了有力的技术支持。同时,本课题所提出的基于VxWorks系统的汉字解决方案对于开发其他语言文字的VxWorks系统也有很好的借鉴作用,笔者也据此初步提出了基于VxWorks 系统的维文方案。本课题所开发的方案在功能、速度、稳定性和兼容性等方面十分出色,对于目标机的硬件环境没有特别要求,可以方便的在各种类型目标机上移植,该方案已经在“十五”国家重点高新工程项目中实施,取得了很好的社会效益和经济效益。更多还原

【Abstract】 With the development of wide application in domestic of embedded real time operatingsystem VxWorks, the old display solving scheme based on VxWorks platform can’t respond tothe request that users increase to the function of this system day by day.Just in order to solve thisproblem, this subject further researches the new display solving scheme --WindML based onVxWorks system, demonstrates the enormous advantages of the new scheme in technology,proceeds with the architecture of WindML, based on WindML basic 2D display scheme,throughthe research and study of the systematic principle of WindML system and different service andmanagement,I have put forward the Chinese solving scheme based on VxWorks system, andthrough the study and research of FreeType 2 font engine and vector font, utilized WindMLsystematic mechanism , have finished the implementation of bitmap and vector Chinesecharacter in VxWorks system, and on the basis of which, have designed and optimized theinquiry algorithm of the Chinese input method editor, developed the Chinese input method editorbased on VxWorks system. This subject has demonstrated and implemented the display solvingscheme based on VxWorks system systematically and integrately for the first time, has offeredthe middleware of developing Chinese system for developers of VxWorks system, has offeredstrong tech support for the extensive application at home of the outstanding embedded real timesystem VxWorks. Meanwhile, the Chinese solving scheme based on VxWorks system that thissubject has put forward has a very good reference function to developing VxWorks system ofother language character too, and I have also put forward the Uighur scheme based on VxWorkssystem preliminary.The scheme that this subject has developed is very outstanding in such aspects as function ,speed, stability and compatibility, to the hardware environment of goal machine, it is notespecially required too, and it is transplanted on all kinds of goal machine conveniently, thisscheme has already been implemented in " 15 " national key high-new project, and has got agood social benefits and economic benefits.更多还原
