Abstract

The invention discloses an AMD video card-based display protocol switching device. The device consists of an AMD video card unit, an SPI bus chip selection unit, a decoding unit and an E2PROM chip unit. A switching method of the device comprises the following steps of: configuring a display protocol; controlling a working state through coding; receiving an HPD signal of a display interface on an external display; and calling a VBIOS program. According to the device and method, multiple abilities and multiple purposes of each AMD video card are realized, the flexibility and compatibility of video card display interfaces are strengthened, types and quantity of video cards in computers are decreased, and the usability of a video card extension function is improved; and the device and method are clear in principle, reasonable in design, easy to realize and high in practical value.

Description

(1) Technical field: [0001] The invention relates to graphics card display technology, in particular to a display protocol switching and device method based on AMD (Advanced Micro Devices—Super Micro Corporation) graphics card. (2) Background technology [0002] With the vigorous development of technology in the IT field, the improvement of chip manufacturing technology and the improvement of manufacturing precision of production equipment, various chip manufacturers are integrating more and more functions on tiny silicon chips, and the types are becoming more and more abundant. The development process of graphics card chips is A good example. [0003] Now the latest technology graphics card chip not only increases the number of display interfaces, but also increases the types of display protocols it supports. The world's two major graphics card chip companies, NVIDIA and AMD, have launched support for multiple display interfaces. And graphics chips that support multiple di...
