High Performance Network Platform Is Homemade! Longcore Four Core C + + Purple Ddr3 Memory

Although there is still a big gap with the advanced level of the world, the progress of domestic semiconductor in recent years is obvious to all, and the performance is catching up.

Recently, the dragon core department has released a high performance network platform "3A3000+7A1000", which realizes the complete domestic, autonomous and controllable application from hardware to operating system.

The program uses the dragon core high-performance 3A3000 quad core processor, which is designed with the dragon core second generation autonomous design 7A1000 bridge, and paste the purple DDR3 4GB domestic memory.

It also supports 6 - way high - speed Gigabit ports, board 16GB SATA NANDriver storage, and M.2, SATA2.0 extensions, 16 PCI-E, 4 channel USB2.0 interfaces, support for VGA display output, and a SPI trusted module for trusted computing extensions.

Compared with the 3A3000+780e platform, the overall performance of the scheme has been greatly improved. It has high localization rate, high performance, high reliability, small size, low power consumption and so on. It is mainly oriented to the independent domestic network security industry, and can be applied to firewall, encryption machine, net gate, VPN, Internet behavior audit and other important gateway equipment.

Longxin 3A3000 is the latest upgrade of the dragon core 3 series processor. Based on the dragon core 3A2000 design, a small amount of structural improvements are made to increase the number of key queue items in the processor core, expand the private / shared cache capacity on the chip, and improve the performance of the main frequency.

At the same time, the frequency of the chip is improved under the new technology. The measured main frequency is breakthrough 1.5GHz, the memory interface meets the DDR3-1600 specification, and the chip substrate bias adjustment support is added to better balance the performance and power consumption.

The overall performance of the chip has been greatly improved, and it continues to maintain forward compatibility, which can directly replace the upgraded Godson 3A1000/3A2000 chip.

Godson 3B3000 supports multi channel concordance with up to four full connected structures on the basis of Godson 3A3000.

Longxin 7A1000 bridge is a chipset facing dragon core 3 processor, which is connected to the processor through the HT3.0 interface, integrated with GPU, display controller and independent memory interface. Peripheral interfaces include 32 road PCIE2.0, 2 Road GMAC, 3 road SATA2.0, 6 way USB2.0, and other low-speed interfaces to meet the desktop and server applications to the IO interface. Requirements and support for high-performance graphics applications through external independent graphics cards.
