Abstract: No matter personal consumer electronic products,or automobiles entertainment systems, they all cry for the desktop environment supporting multitask. User-friendly multitask support brings easy and convenient experience. A strong embedded ecosystem should provide basic desktop functions and applications for daily needs as well as tools and documentation for developers to write stand-alone applications for the system. With Daemon thread and well-known Pipe mechanism, a desktop environment supporting multitasks was implemented, and the paper introduced a method to develop the SDK for programmers.
