For the deficiencies in the prior art, the technical matters that quasi-solution of the present invention is determined is: a kind of For Embedded Computer On Modules based on Godson 2F is provided.The specific functional module of this module integration, and define on this basis a kind of private bus, to meet the application of special occasions.

The solution that the present invention solve the technical problem is: design a kind of single board computer module based on Godson 2F CPU, comprise that Godson 2F CPU, private bus, FLASH circuit, DDR2 memory grain, 100,000,000 networks, a TFT demonstration, video display module, VGA demonstration, South Bridge chip group, a USB, No. two USB, SSD memory module and No. two TFT show; Described Godson 2F CPU is connected with 100,000,000 networks 5, video display module, South Bridge chip group by pci bus, by local bus, is connected with private bus, FLASH circuit; Described DDR2 memory grain is directly connected on Godson 2F CPU; Described No. two TFT show and are connected with Godson 2F CPU by local bus; Described VGA shows and is connected with video display module by display interface; Described South Bridge chip group is connected with a USB, No. two USB, SSD memory modules respectively by the special purpose interface of himself.

Compared with prior art, in computer module of the present invention, nonresident portion plate carries memory grain, is directly welded in printed board, thereby also can normally uses under the larger environment of oscillation intensity; Plate carries video display module can process arbitrarily on-the-spot various images, and can carry out image overlap-add procedure, is applicable to some specific environment demands; The realization of private bus is simpler aspect data processing and modular requirement, and reliable operation, and applicability is strong.

Accompanying drawing explanation

Fig. 1 is composition structure and the principle of work block diagram that the present invention is based on a kind of embodiment of For Embedded Computer On Modules of Godson 2F.

Embodiment

Below in conjunction with embodiment and accompanying drawing thereof, the present invention is described in more detail.

The For Embedded Computer On Modules based on Godson 2F (being called for short computer module, referring to Fig. 1) of the present invention design comprises: Godson 2F CPU1, private bus 2, FLASH circuit 3, DDR2 memory grain 4,100,000,000 networks 5, TFT show 6, video display module 7, VGA show 8, South Bridge chip group 9, a USB10, No. two USB11, SSD memory module 12 and No. two TFT show 13; Described Godson 2F CPU1 is connected with the pci bus signal of 100,000,000 networks 5, video display module 7 and South Bridge chip group 9 respectively by the pci bus signal carrying, and by the local bus signal carrying, is connected respectively with private bus 2 with the bus signals of FLASH circuit 3; Described DDR2 memory grain 4 is directly connected on Godson 2F CPU1; Described No. two TFT show that 13 are connected with Godson 2F CPU1 by local bus; Described VGA shows that 8 are connected with video display module 7 by display interface; Described South Bridge chip group 9 is connected with SSD memory module 12 with USB10, No. two USB11 respectively by the special purpose interface of himself.

Described DDR2 memory grain 4 is directly welded in printed board by pad, and vibration proof effect is extremely strong like this, and the DDR2 memory grain 4 that the present invention adopts is HY5PS1G163CFP of Modern Corporation, welds altogether 8 particles, and composition memory size is 1GB.Traditional computer module is to be all connected with Godson 2F CPU1 by memory bank, and under the larger environment of oscillation intensity, memory bar can produce loosening, produces computer module and starts mistake, causes the computer module can not normal boot-strap.

That described 100,000,000 networks 5 adopt is the RTL8139 of REALTEK company, embedded OS that can down loading updating computer module by 100,000,000 networks 5.

Described FLASH circuit 3 is for depositing the bios program of Godson 2F CPU1.

Described South Bridge chip group 9 is for expanding external unit.

Described VGA shows that 8 interfaces are directly drawn by the dedicated display interface of video display module 7, for connecting VGA display screen.
