VPX mainboard based on Godson processor

Abstract

The invention particularly relates to a VPX mainboard based on a Godson processor. The VPX mainboard uses the Godson 3B eight-core processor as a platform, is 1.2 GHz-1.5 GHz in main frequency and is supportive of surface memory sticking and adaptive to an RS780E+SB710 chip set of AMD, and an SATA NAN Drive embedded flash memory single-chip hard disk is adopted; a VPX architecture is adopted, and one group of VGA signals, one group of DVI signals, one group of KB / MS signals, eight groups of USB2.0 signals, eight groups of URAT signals and four groups of 10 / 100 / 1000 MPs Ethernet signals, one group of PCI signals and one group of PCIE*16 signals can be provided. The homemade Godson 3B processor is adopted, and software and hardware are autonomous, controllable, safe and reliable; the VPX architecture and a design scheme of board hard disk carrying and surface memory sticking are adopted, so that reinforcing performance of the mainboard is improved greatly, and the mainboard has high durability, shock resistance and reliability and is enabled to meet harsh requirements of servers for military use and ensured to be capable of normally and stably working in severe field environment.

Description

technical field [0001] The invention relates to the technical field of VPX motherboards, in particular to a VPX motherboard based on a Loongson processor. Background technique [0002] In recent years, CPCI (CompactPCI) bus and VME (VersaModuleEurocard) bus are in a state of mutual competition and development, and have been widely used in the field of military computers. However, with the advent of the era of massive storage data, the indicators of computer's demand for broadband and expansion have been further improved, and the current two buses have encountered bottlenecks that are difficult to break through. [0003] In order to meet the needs of greater bandwidth and stronger cooling capacity, VITA (VME International Association) successively launched the VPX bus technology standard (VITA46) and REDI reinforced mechanical design specification (VITA48) in 2006. All VPX adopts MultiGigRT2 connectors, which have the advantages of tight and firm connection, low insertion lo...
