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. |
