| Abstract: |
| To satisfy the requirement of functional complexity and reduction of d
eveloping periods in the field of highly integrated embedded system, this paper
presents a method and some kernel points of the graphic drivers developm
ent based on WindML, a multimedia developing library in the embedded ope
rating system VxWorks, by taking an example of hardware platform constructed by
the ARM9 processor EP9315. The presentation contains the description of the ins
tallation and initialization, programing of plotting function and importing of t
he hardware acceleration about the graphic drivers, in order to offer some refer
ence for the application of display and control function development in projects. |
| Key words: embedded platform graphic drivers multimedia developing library hardware acceleration |
