Self-controlled computer mainboard

Abstract

The invention discloses a self-controlled computer mainboard, which comprises a COMe mainboard, a CPCI pinboard, and a power module for supplying power for the COMe mainboard and the CPCI pinboard. The COMe mainboard comprises a processor, a bridge ribbon and a memory; the CPCI pinboard comprises a PCIe to PCI bridge chip; the processor adopts a Loongson 3A serial processor; the bridge ribbon adopts a Loongson 2H chip; the memory adopts a DDR3 memory grain chip; the Loongson 3A serial processor is connected with the Loongson 2H chip through an HT bus; the Loongson 3A serial processor and the Loongson 2H chip are connected with the DDR3 memory grain chip through memory channels; an EJTAG debugging interface used for carrying out reliability testing on the Loongson 3A serial processor and the Loongson 2H chip is also arranged on the COMe mainboard. According to the self-controlled computer mainboard provided by the invention, the Loongson 3A serial processor and the Loongson 2H matched bridge chip with full autonomy proprietary intellectual property rights are adopted, and the hardware interface of a mainboard platform is arranged, so that higher product domestication rate can be realized, the demands on information safety and self-controllability are met, and the technical risks and the uncontrollable hidden dangers in product use and maintenance are eliminated.

Description

technical field [0001] The invention belongs to the technical field of computer motherboards, and more specifically relates to an autonomously controllable computer motherboard. Background technique [0002] For a long time, my country's computing equipment has adopted a large number of foreign software and hardware products, and core technologies such as high-performance processors and operating systems have been completely closed to us. Technology is controlled by others and there are security risks. The "Prism Gate" incident shows that the United States has the intention, means, and ability to carry out network penetration attacks on my country through its information products. At present, the foreign software and hardware products purchased by the government and the military may have built-in backdoors and loopholes, which have become leaks. Even a major security risk to the normal operation of the information system. In recent years, through the arrangement of the natio...
