| With the rapid advances in the information technology, the embedded systems arenow being widely employed in many applications, such as the information appliance,network device, industrial control, intelligent transportation systems.Embedded software is the core of designing the embedded system, whileembedded operating system plays an important role in the embedded software. Thecurrent embedded operating system is now stepping into an era from general embeddedoperating system to application specific embedded operating system. The EmbeddedLinux System has become a research hotspot, because of its open source and excellentnetwork performance.Firstly, the paper summarizes the character and development of the embeddedsystem and the embedded operating system, and gives the opinion about the choice ofApplicationspecificembedded platforms, both the hardware and the software. Secondly,the paper examines a kobject hierarchy, and analyses the realization of the platform buson Embedded Linux System. Thirdly tells the focus and difficulties of the entireembedded system software design. Finally introduces the realization of ALSA driverbased on the Intel XScale architecture. |
