Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] The present invention provides a dual independent graphics card dynamic switching device based on Feiteng platform, such as figure 1 As shown, including: system motherboard, graphics card switching control module, foreign high-performance independent graphics card and domestic independent graphics card. Wherein, the independent graphics card is connected to the PCIE slot of the motherboard, and a standard PCIE slot is used for connection between the independent graphics card and the system motherboard. Two discrete graphics cards connected to their respective monitors.

[0020] (1) System board

[0021] The main board of the system includes an independent controllable processor Feiteng CPU, a general-purpose PCIE switching chip, and a standard PCIE slot; the general-purpose PCIE switching chip is used to output PCIE×16lane to the PCIE slot, and PC...

Abstract

The invention discloses a double independent graphics card dynamic switching device and method based on a Feiteng platform. By using the device and method, free switching between foreign high-performance independent display card display and domestic independent display card display can be realized on a universal Feiteng platform, and convenience is brought to a user. A foreign high-performance independent display card and a domestic independent display card are connected with a Feiteng CPU through PCIE slots. A display card existing in a system is actively recognized through a display card switching control module, and display output is conducted according to display card information and display priority setting of the display card information. When the user needs to switch the video cards, the domestic independent video card and the foreign high-performance independent video card can be freely switched for the display only by triggering the button, so that the use of the user is greatly facilitated, and the balance between an autonomous controllable requirement and a high-end graphic application requirement is met.

Description

technical field [0001] The invention relates to the technical field of computer display switching, in particular to a dual independent graphics card dynamic switching device and method based on a Feiteng platform. Background technique [0002] At present, the display switching technology of x86 computers is only implemented on notebook computers. Generally speaking, this kind of notebook is based on the CPU with integrated display core of Intel or AMD, and adopts the operating system above win7. In order to improve the graphics processing capability, an independent graphics card is inserted on the device. , ATI and NVIDIA's smart graphics switching technology can be used to automatically switch seamlessly between the core display and the independent display according to the system load level. At present, the display core has not been integrated on the self-controllable CPU, and this intelligent graphics card switching technology cannot be realized on the self-controllable co...
