[0009] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of the present application provided below in conjunction with the drawings is not intended to limit the scope of protection of the present application for which protection is sought, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. The present utility model is further described below in conjunction with the drawings.

[0010] like Figure 1 As shown, the utility model specifically relates to a domestically produced small computer display module based on the Loongson 2K2000 processor, with the purpose of solving the problems of low independent controllability and few functional interfaces in the domestic display and control module product line. It is mainly composed of a 2K2000 processor, a power module, a COMe connector and an FPGA.

[0011] The designed 8GB DDR4 memory is obtained by connecting 8 8-Bit DDR4 particles through the processor's DDR4 interface; the selected domestic DDR4 chip is implemented; SATA, USB, I2C, HDMI, and PCIe interfaces are directly brought out through the processor; 2-way LAN network interfaces are directly brought out to the COMe connector through the processor, 10 / 100 / 1000Mbps adaptive Ethernet network, which can be divided into two groups to achieve redundant backup of the network interface.

[0012] Furthermore, the processor's LPC and DVO / LIO multiplexing interfaces are connected to a domestically produced high-speed FPGA, with signal conversion and interface expansion implemented through FPGA-designed logic. Software settings can be configured during startup. When the processor interface is configured in DVO display interface mode, LVDS and DVI signals can be displayed and output; when the processor interface is configured in LIO interface mode, CAN and UART interfaces can be expanded; when the processor interface is configured in LPC interface mode, UART and PS2 interfaces can be expanded. Power management utilizes a domestically produced FPGA chip for power-on sequencing and reset logic control, and the processor manages the FPGA via the derived I2C bus. The power supply uses a domestically produced 4644 power module, and the FPGA utilizes a domestically produced Fudan microchip.

[0013] Interface signals (power, network, serial port, CAN interface, GPIO interface) are all led out of the COMe connector and processed through isolation devices, which can effectively improve the overall reliability of the board. Interface signals are all led out through the COMe connector, which uses a high-speed, high-reliability connector.

[0014] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention may be used in various other combinations, modifications, and improvements, and may be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant fields. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention shall be within the scope of protection of the appended claims.
