Problems solved by technology

[0005] Currently, self-controllable computers based on domestic CPUs do not support high-end graphics cards. Although they can meet most of the display requirements in daily office scenes, there are still performance bottlenecks: the CPU usage is too high when multiple videos are played at the same time, resulting in smooth computer operations. Insufficient; situational system target zoom roaming response time is long, etc.
The above shortcomings seriously affect the user experience and hinder the application of autonomous controllable computers in more fields

Embodiment Construction

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0032] The invention provides a dual independent graphics card synchronous display device based on Feiteng platform, the device includes a system mainboard, two domestic independent graphics cards, and a dual graphics card synchronous display module. The system motherboard provides 2 standard PCIE×16 slots. Two independent graphics cards are respectively plugged into the PCIE×16 slots of the main board, among which the graphics card A on the PCIE×16 slot A is the main card, which is connected to the monitor to provide external display information; the graphics card B on the PCIE×16 slot B is the secondary card, Do not output display information directly to the...

Abstract

The invention provides a Feiteng platform-based double-independent graphics card synchronous display device. The device comprises a system mainboard, two domestic independent graphics cards and a double-graphics card synchronous display module, the system mainboard comprises a domestic Feiteng CPU, Kunlun BIOS firmware, a Kylin operating system, a general PCIE switching chip, a PCIE configurationchip, two PCIE * 16 slots, namely a PCIE * 16 slot A and a PCIE * 16 slot B, wherein the PCIE * 16 slot A and the PCIE * 16 slot B are used for being connected with independent graphics cards in an inserted mode; a display card A on the PCIE * 16 slot A is a main card and is connected with a display to provide display information to the outside; and a display card B on the PCIE * 16 slot B is an auxiliary card and does not directly output display information to the outside. The invention provides a double-graphics-card synchronous display method of a domestic Feiteng platform. The number of primitives rendered by a single display card is reduced, the rendering time is shortened, the rendering speed is finally increased, the graphic performance of the whole machine is remarkably improved, the fluency under the condition that multiple videos are played at the same time is improved, the target scaling roaming response time of a situation system is shortened, and the fluency and user experience are improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a device and method for synchronously displaying dual independent graphics cards based on a Feiteng platform. Background technique [0002] Dual graphics card synchronous display technology is a method that uses two graphics cards to work synchronously and cooperatively to improve the display performance of the whole machine. At present, the mainstream technologies for synchronous display of dual graphics cards in foreign countries are NVIDIA's SLI technology and AMD's Crossfire technology. These two technologies are equipped with two graphics cards on the same motherboard, the frame data processed by the two graphics cards are collected and processed, and output as a whole signal, and the display performance of the entire system is improved through the cooperative work of the two graphics cards . There are still some differences between SLI technology and Crossfire technology in terms...
