摘要
随着后PC时代的到来,越来越多的产品中嵌入了计算机。eCos这种嵌入式可配置操作系统层次分明、接口合理,便于嵌入式系统开发,但是其面向嵌入式X86架构的支持不足,需要改进。结合嵌入式X86架构系统的特点,分析eCos对嵌入式X86架构的不足之处,及完善的可行性。针对eCos对嵌入式X86架构支持的不足,对eCos的引导方式、图形显示驱动、和窗口系统支持的不足进行了完善的实现。改进后的系统运行稳定和可靠,更好地支持了嵌入式X86架构环境。
With the coming of the Post-PC-Era , more and more products today have been embedded with computers. As a configurable embedded operating system, eCos has well designed architecture and interface, which can ease the programming work of embedded System. Based on the features of embedded-pc, the paper place its emphasis on the support of embedd-pc that eCos can provide, and analyse the shortages of eCos and the feasibility of atonement. At laster, aim for the shortages of eCos on supporting embedded-pc, the paper discuss boot method, graphics display driver, windows support etc. problems we have resolved in detail. It is stable and dependable, can support embedded X86 environment preferably.
