The Research And Design Of Graphic User Interface Of Embedded System Based On Linux

In the fast-changing world of embedded, handheld and wireless devices, there are many hardware and software design changes taking place. Many devices now feature 32-bit microprocessors from Intel, MIPS and Motorola, as well as larger LCD graphical displays. In order to leverage the significant results gained in the last ten years, many developers are turning to using friendly user interface operating systems with these new embedded designs.One of the most promising emerging areas seems to be running Linux in these environments, for a couple of good reasons: Linux on embedded systems brings with it the entire power of desktop computing. Linux also supports all the new microprocessors typically included in embedded designs. Finally, Linux is free, with no royalty payments required for its use.So using linux as operating system, with a GUI system built on, seems to be a good solution.For the handled devices on the market such as PDA, as to the poor hardware in old days, the user interface was very simple, we could hardly see the colorful GUI which was supported by PC. But recently we found that some embedded operating systems such as Windows CE and Palm OS, have supported complete GUI features. With the great performance improvement of the hardware, we think that the need for mini GUI systems is urgent.By designing and developing the GUI system of a multifunction printer, do the research relatively on embedded GUI system architecture, design and implement the operation and display on GUI of multifunction printer.Finally through the analyzing and tests, the result of performances proves that the design thought and performance methods are reasonable and practical. And onwards, these are valuable to the exploitation of similar software.
