Aiming at the problem that most embedded processor can’t support high-resolution display or can’t work efficiently in high-resolution display, apply SM502 to embedded system. Briefly introduces the characteristic of the system and work principle, and analyzes the hardware and software design method. The interface of SM502 to processor uses Configuration C. And the design of SM502 driver includes SM502 structure of device driver, the structure device driver data. The chip has been successfully applied to a certain type individual soldier system, greatly improves the capacity of multimedia processing of the system, and achieves high efficiency.
