Design and Implementation of MDDI Protocol for Mobile System

In this study, we propose how th implement a MDDI(Mobile Display Digital Interface) protocol packet generation method in software. MDDI protocol is widely used in mobile display device. MDDI protocol packets are generated by software within micro processor. This method needs the minimum hardware configuration. In order to implementation of this method, we design a hardware platform with a high performance microprocessor and a FPGA. The packets generated by software within microprocessor are converted into LVDS signals, and transmitted by hardware within FPGA. This study suggests the benefits of the way how software can easily create a variety of packet. But, this proposed method takes more time in packet transmission compared to the traditional method. This weakness remains as a future challenge, which can be soon improved.
