Application of Multimedia Coprocessor SM501 in Full Color LED Screen Off-Line Display System
A novel design for full color LED screen off-line display system based on embedded system was proposed in this paper. The goal of this project is to develop a solution of tiny off-line display system which can support full color high definition LED screen. The multimedia coprocessor SM501 was adopted to solve the bottleneck of display system in a typical embedded architecture. Software interface of 2D graphic acceleration for SM501 was designed to speed up the display and optimize the video play. This project solved the limitations in current LED off-line control card
such as support only homochromy or pseudo color LED screen
support only low definition screen and does not support for high quality video display.
