Embodiment Construction

[0015] A Loongson 3A+2H chipset computer mainboard based on VPX standard, including Loongson 3A quad-core processor, Loongson 2H bridge, motherboard and hard disk, the main frequency of Loongson 3A quad-core processor is 1GHz, connected by onboard SATA socket SATA hard disk, the hard disk capacity is 256GB, the Loongson 3A quad-core processor is connected to the 4G memory; 1 set of DVI display signals, 6 sets of USB2.0 data signals, 3 sets of Ethernet signals and 1 set of PCIE*1 signals.

[0016] Referring to the attached figure, the Loongson 3A quad-core processor can be connected to the Loongson 2H bridge through the 8-bit HT bus because the Loongson 3A quad-core processor has its own HT bus controller, and because the Loongson 3CA processor comes with two DDR2 memory controllers , so the Loongson 3A quad-core processor can be directly connected to the memory slot.

[0017] The Loongson 2H bridge chip integrates a PCIe controller, which is configured as four PCIe x1, three ...

Abstract

The invention relates to the field of computer motherboard, in particular to a Loongson 3A+2H chipset computer motherboard based on VPX standard. The computer motherboard comprises a Loongson 3A quad core processor, a Loongson 2H bridge plate, a motherboard and a hard disk, wherein the main frequency of Loongson 3A quad core processor is 1 GHzz, the processor uses on-board SATA base to are connected with SATA hard disk, the capacity of hard disk is 256GB, the link table of Loongson 3A quad core processor has memory of 4G; motherboard use VPX architecture and can provide 1 group of KB / MS mouse and key interface, 8 lines of URAD signal, 1 group of VGA display signal, 1 group of DVI display signal, 6 groups of USB 2.0 data signal, 3 groups of Ethernet signal and 1 group of PCIE*1 signal; the motherboard uses domestic Loongson 3A processor and Loongson 2H bridge plate. The software and hardware of the motherboard realize autonomous control. At the same time, the motherboard uses VPX architecture, the design proposal of on-board hard disk and memory of table improves the reinforcement performance greatly.

Description

technical field [0001] The invention relates to the field of computer motherboards, in particular to a Loongson 3A+2H chipset computer motherboard based on the VPX standard. Background technique [0002] Existing motherboards composed of Loongson CPUs generally use AMD chipsets SB710 and RS780 to complete the work of the north and south bridges, while AMD chips are chips with foreign property rights, and various external interfaces are expanded through this chipset, which cannot be used in the field of military computers. Avoidance carries great risk and is very limited. Under the background of the localization of domestic computers in our country, it is imminent to develop a computer chipset mainly composed of domestic components. Contents of the invention [0003] In order to overcome the above-mentioned problems, the present invention provides a kind of Loongson 3A+2H chipset computer motherboard based on VPX standard, the Loongson 3A+2H chipset based on VPX standard o...
