Abstract
This paper presents an implementation of the DisplayPort AUX(Auxiliary) Channel. DisplayPort uses Main link, AUX Channel and Hot Plug Detect line to transfer the video & audio data. For isochronous transport service, source device converts to image and audio data which are to be transported through the Main Link and transports the restructured image and audio data to sink device. The AUX Channel provides link service and device service for discovering, initializing and maintaining the Main link. Hot Plug Detect line is used to confirm the connection between source device and sink device. The AUX Channel is implemented with 3315 LUTs(Look Up Table), 1466 Flip Flops and 168.782MHz max speed synthesized using Xilinx ISE 9.2i at SoC Master3.
