基于VxWorks系统的二维硬件加速显示驱动技术

摘要

For the graphics driver which supported by VxWorks can't meet the needs of users very well. A technology of graphics driver based on 2D acceleration engine is presented, which achieves these functions in UGL such as 2D acceleration, hardware cursor, double buffering, Overlay surface. Then the performance of the graphics system is improved, and the application needs of real-time systems is met. At present, the design has been applied to verify in multi-type naval equipments%针对当前VxWorks系统图形显示驱动已无法满足用户需求的问题,提出了一种基于二维(2D)硬件加速引擎的图形显示驱动技术,实现了UGL的二维硬件加速、硬件光标、硬件双缓冲、Overlay覆盖等功能,提高了VxWorks系统的图形显示性能,满足了实时系统的应用需求.目前该设计已在多型海军装备中得到应用验证.
