Two-way server mainboard based on Loongson 3B3000 processor

Abstract

The invention provides a two-way server mainboard based on a Loongson 3B3000 processor. The two-way server mainboard is integrated with a first Loongson 3B3000 processor, a second Loongson 3B3000 processor, a Loongson 7A1000 bridge chip and a BMC management chip. The first Loongson 3B3000 processor and the second Loongson 3B3000 processor are connected through an HT0 * 16 bus. The first Loongson 3B3000 processor and the second Loongson 3B3000 processor are respectively connected with the Loongson 7A1000 bridge sheet through an HT bus; the first Loongson 3B3000 processor and the second Loongson3B3000 processor are both connected with a memory unit; the second Loongson 3B3000 processor is connected with an RS232 serial port and a TTL debugging serial port; the second Loongson 3B3000 processor is connected with an SPI FLASH chip and an SOC card slot through an either-or channel switching chip; and the BMC management chip is connected with the Loongson 7A1000 bridge chip through a PCIE bus and a USB bus. The two-way server mainboard is used for improving the autonomous controllability of the domestic computer mainboard.

Description

technical field [0001] The invention relates to the field of servers, in particular to a dual-way server mainboard based on the Loongson 3B3000 processor. Background technique [0002] For a long time, my country's computer 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, making it impossible to deeply grasp the core technical principles, resulting in technical risks and uncontrollable safety hazards in the use of products . [0003] Information security is an important indicator in future information warfare. In the networked combat environment, the enemy can launch information attacks everywhere, and it is impossible to guard against them. The demand for domestic high-performance server platforms is imperative. [0004] The dual-socket server is a computer with much more complex functions than ordinary PCs. It is mainly used in ...

Problems solved by technology

[0005] However, the existing dual-socket servers are still limited by foreign software and hardware products. Although the degree of limitation has been reduced, there are still relatively large technical risks and uncontrollable security risks in the use of products.
