| Abstract: | Based on Freescale MX51 hardware platform, this paper gives a solution for DVI video display interface in high definition em- bedded system. By LCD1 interface of the processor, the design achieves DVI video output with expansion chip TFP410. The paper analyzes the mechanism of framebuffer and its application. It introduces in detail how to develop DVI device driver for framebuffer in Linux2. 6. 28 system. This solution is used for high definition set top box product with good effect. |
