Accompanied by the development of multimedia display and transmission technology, people get more and more high audio-visual enjoyment. From traditional analog TV, SD, HD, Full HD. Line with the to display technological development go hand in hand to show the development of interface technology from analog AV terminals, S-Video and VGA interface to the digital display DVI interface, technically experienced a transition from analog to digital, from parallel to serial from low speed to high speed the development process. HDMI is the latest High-Definition Multimedia Interface, its specification by Silicon Image seven companies with large bandwidth, small size, long distance transmission, and support genuine protection functions, in line with the development trend of today's technology, once introduced, it a huge success. Become one of the standard interface for flat panel displays, high-definition TV and other equipment, and more widely used. From the 1980s since the XILINX invented the first FPGA chip, FPGA for its architecture and logic unit flexible computing speed fast, convenient programming, etc. widely used in the IC design, system control, video processing, communication systems, aerospace and many other aspects. This article the use of the ALTERA a high-end the FPGA chip EP2S180F1508C3 as the core, with the Silicon Image the dedicated HDMI receiver chip built an HDMI receiver platform. HDMI wide bandwidth, and the large amount of data, the use of a new type of DDR2 SDRAM as a video signal input and output buffer. Hardware board-level design, HDMI and DDR2 high speed circuit, with a series of high-speed circuit design, to avoid signal reflection, crosstalk, and other undesirable phenomena. On the basis of in-depth study of the HDMI specification and DDR2 SDRAM timing specifications written in ALTERA development platform QUARTUS Ⅱ top-level module and each functional sub-module, and simulation through. The main thesis work and innovation is reflected in the following aspects: 1 thesis latest HDMI interface specification, and a new memory device DDR2 timing specifications. Papers to build the entire system is enormous, and it comes to norms, information on a variety of chip, the use of various software tools schematic drawing and PCB layout until the latter part of the programming, the cost of a large number of simulation The time and effort. 3, the paper used for the first time the FPGA to handle HDMI signals directly drive display devices, as distinguished from the general ASIC program. 4 papers on high-speed circuits, especially the DDR2 layout, using a series of special measures has certain reference value.
