Creative Instructions () Creative Jaws: This creative is about the improvement of a computer backplane with graphics acceleration port (AGP), especially about A computer backplane with an external CPU interface card enables different types of buses to communicate between the CPU interface card and the computer backplane. Creative background: With the advancement of information technology, the overall computer industry has been rapidly developed, especially in the manufacturing industry, where industrial computers are widely used to control the manufacturing process of various products. In order to increase the production capacity of products, the main peripheral devices used in industrial computers, such as Central Processing Unit (CPU) interface cards and graphics cards, must be designed with high-speed computing and fast display as the focus. However, in the field of industrial computer applications, each industrial computer or server may communicate with other computers at the same time, or use a terminal to remotely control the production process. However, whether it is communication or remote control, you need to use the display card to transfer the operation screen to and from the computer server and other computers or terminals. However, the display speed of the operation screen is closely related to the bus specifications of the display card. Please refer to Figure 1 for a schematic diagram of the basic architecture of a traditional industrial computer. The industrial computer mainly includes a computer backplane 100 and a CPU interface card 102. The CPU interface card 102 uses one of the lower edges of the ISA golden finger 104 and a peripheral component interconnect (PCI) golden finger 106 to be inserted vertically and simultaneously. Electrically connect the ISA expansion slot 108 and PCI 2 on the aforementioned computer backplane 100. This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page ) --Installation-. ·-丨 Line M242739 C7 D7 V. Creative Instructions () (Please read the precautions on the back before filling this page) Expansion slot 110, and one side of the CPU interface card 102 is soldered directly to a drawing Acceleration port (AGP) expansion slot 112, for horizontally receiving an external AGP display card 114, and then using an AGP cable (not labeled) to electrically connect it to a display or terminal, where the AGP is currently Common display interface specifications. When an industrial computer is used, data is transmitted between the CPU interface card 102 and the computer backplane 100 through the ISA bus 104 and the PCI bus 106 respectively defined by the ISA gold finger 104 and the PCI gold finger 106. However, since the AGP display card 114 is inserted horizontally in the AGP expansion slot 112 in a manner perpendicular to the CPU interface card 102 outwards, this horizontal insertion method will occupy space adjacent to other expansion slots (not shown). This drastically reduces the number of interface cards that can be used. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Although traditionally the components of the AGP graphics card can be directly built-in (Onboard) on the CPU interface card 102, the user cannot select the required graphics card. When users need to use different types of graphics cards for different purposes, the built-in AGP display interface becomes a waste. In other words, the user must pay extra costs for the built-in AGP display interface and reduce the flexibility of choosing other graphics cards. At the same time, designing the AGP expansion slot 112 on the CPU interface card 102 will cause its related circuit layout and external cable connectors (not shown in the figure) to occupy a lot of the CPU interface card's use area, which will force the volume of the CPU interface card virtually. The design must remain huge. Therefore, how to improve the proper configuration of AGP to reduce the size of the CPU interface card and increase the flexibility of the graphics card will be an issue that needs to be solved in the design of computer backplanes.
