Embodiment 3
[0032] A kind of configuration method of the MXM graphics card based on the Godson processor computer platform of the present invention, based on the Godson processor computer platform, a MXM graphics card is embedded in the display design in a combination of software and hardware, so as to realize the MXM graphics card in the Godson processor Adaptation and application of computer platforms.
[0033] Such as figure 1 As shown, the design hardware circuit is composed of MXM graphics card, graphics card carrier board, and the backplane of the computer motherboard. The signal interaction between the MXM graphics card and the motherboard is mainly completed through the graphics card carrier board and the backplane. Control, in order to achieve dual-screen display, it is necessary to pull the 4 sets of differential signals of the PORT-B port on the MXM graphics card to the CPCI connector for outputting DVI signals. The bus interface conforms to the CPCI and MXM interface specifica...
