Problems solved by technology

[0004] In an environment where the military is vigorously advocating independent and controllable development, a batch of latest achievements based on domestic processors, firmware, and operating systems are gradually being applied to national defense and military informatization construction. Performance is still lacking
Although the technology of Loongson processor is relatively mature, its integrated display performance is poor, and the independent graphics card models that are successfully adapted are extremely limited. Not only are the performance low-end, but most of them have been discontinued. The above bottlenecks limit the application of domestic computers in video processing of vehicle electronic systems.

Abstract

The invention discloses an MXM graphics card configuration method based on a Loongson processor computer platform and belongs to a graphics card configuration method. The method aims to solve the technical problem about how to configure an MXM graphics card on the Loongson processor computer platform. According to the technical scheme, applied hardware comprises the MXM graphics card, a graphics card carrier board and a backboard of a computer mainboard, signal interaction between the MXM graphics card and the computer mainboard is completed through the graphics card carrier board and the backboard, a CPCI connector is arranged on the graphics card carrier board, an interface output signal of the MXM graphics card is transmitted to the backboard by the graphics card carrier board through the CPCI connector, driving codes of a computer system are changed, and the MXM graphics card can be supported by a computer driver; a control program between the MXM graphics card and a driving program is changed, an output port of DVI signals is assigned, and differential signals required by a DVI interface are output through the assigned output port.

Description

technical field [0001] The invention relates to a configuration method of a graphics card, in particular to a configuration method of an MXM graphics card based on a Loongson processor computer platform. Background technique [0002] Loongson (English: Loongson, formerly known as GODSON) is a general-purpose CPU designed by the Institute of Computing Technology, Chinese Academy of Sciences. It adopts the MIPS reduced instruction set architecture and has obtained the patent authorization of MIPS Technology Corporation. The frequency of Godson-1 is 266MHz, which was first used in 2002. The highest frequency of Godson-2 is 1GHz. Loongson 3A is the first domestic commercial 4-core processor with a working frequency of 900MHz~1GHz. The peak computing power of Godson 3A reaches 16GFLOPS. Loongson 3B is the first domestic commercial 8-core processor with a main frequency of 1GHz, supports vector computing acceleration, and a peak computing capacity of 128GFLOPS, with a high perf...
