Research And Development Of Embedded System Based On ARM

With the d evelopment of Internet and the arrival of Post-PC times, the application o f embedded system becomes popular. Now embedded technology has been the focal point of research. Embedded product have possessed great proportion in IT field. The embedded technology based on ARM has become a spot light of current embedded field.This paper introduces an embedded processor EP7312 as well as an embedded operating system uC/OS-II, and analyzes hardware composition( LCD, UART, Touch-Screen) in details. The emphasis is on the realization of hardware drive. The EP7312 has been applied in the user machine of Double Stars Positioning System successfully.
