摘要
文在简单介绍高清电视音视频解码平台HDTV SoC和图形界面支持系统MiniGUI的基础上,详细给出了在HDTVSoC平台上移植MiniGUI的思路和所需解决的关键问题,同时为SoC平台的OSD硬件设计了专用的framebuffer驱动程序,并最终实现了MiniGUI在SoC平台上的移植工作,证明了本论文设计的正确性和可行性。
This paper firstly introduces the HDTV SoC platform, applied for audio and video decoding in set-top box of High Definition Digital Television, and analyzes the characters and the design structure of the graphic user interface system-MiniGUI.. A porting method is discussed based on the hardware and software platform. At last, the porting is implemented by the designation of the framebuffer device driver of the OSD hardware of the platform. The porting method introduced here is helpful to building GUI in an embedded system and is verified by practice.
