Abstract
The invention discloses a detachable main board. The main board comprises a core board and a base board, wherein a master chip, a double data rate (DDR) memory and a FLASH memory are arranged on the core board, the DDR memory and the FLASH memory are connected with the master chip, an interface device and an optional functional device are arranged on the base board, and the core board is arranged on the base board in a detachable mode. According to the main board, upgrade and development cycles of the main board can be shortened, and resources are saved.
Description
Technical field
The present invention relates to a kind of replaceable mainboard, refer in particular to a kind of ARM series replaceable mainboard.
Background technology
In the prior art, master chip, FLASH flash memory, DDR internal memory, interface device and apolegamy function element (as: bluetooth, WIFI/3G, gyroscope, compass and gravity sensor etc.) generally all are arranged on the same substrate, form the mainboard of independent module.Namely carry out separately hardware development for different application demands.Therefore, it has following defective:
One, in the actual development process, a lot of hardware circuits all are identical or similar, cause overlapping development, thereby cause mainboard upgrade cycle long, and every kind of type all will repeat to purchase master chip, DDR internal memory and FLASH flash memory, and these materials hand over phases all long, just caused each project volume production cycle, the R﹠D cycle all can be elongated;
Two, when needs are upgraded to master chip, need to change whole mainboard, cause the duplications of production such as FLASH flash memory, DDR internal memory, interface device and apolegamy function element, the serious waste resource.
In view of the prior art defects, the inventor develops a kind of replaceable mainboard that overcomes defects, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of replaceable mainboard that can shorten the R﹠D cycle and economize on resources.
For reaching above-mentioned purpose, solution of the present invention is:
A kind of replaceable mainboard comprises core board and substrate; The DDR internal memory and the FLASH flash memory that are provided with master chip on the core board and are connected with master chip; Interface device and apolegamy function element are arranged on the substrate; Core board connects in disconnectable mode and is arranged on the substrate.
Further, disconnectable mode is: core board is designed to the size of DDR3 memory bar, inserts the DDR3 internal memory socket that is arranged on the substrate, with input-output device (I/O equipment) communication of substrate.
Further, master chip is the little RK2918 of auspicious core.
Further, the apolegamy function element is bluetooth, 3G, gyroscope, compass and gravity sensor.
After adopting such scheme, core board of the present invention is arranged on the substrate in disconnectable mode, forms the removable mainboard of core board, compared with prior art, has the following advantages:
One, shorten R﹠D cycle of mainboard, the mainboard of each project can be selected different core boards, will match simultaneously function element and carry out design debug and can make project mainboard volume production;
Two, when need were upgraded to mainboard, the core board of directly upgrading got final product, thereby saved the update time of mainboard;
Three, the core board of all mainboards can share, and can satisfy disparity items to the different requirements of mainboard as long as be equipped with different core boards, reduces the risk of getting the raw materials ready, and reduces simultaneously the difficulty of getting the raw materials ready of thing control (PMC).

Fig. 2 is concrete structure schematic diagram of the present invention.
Label declaration
DDR internal memory 12 FLASH flash memories 13
Apolegamy function element 22.
Embodiment
The present invention is described in detail below in conjunction with drawings and the specific embodiments.
Consult Figure 1 and Figure 2, a kind of replaceable mainboard that the present invention discloses comprises core board (Core Board) 1 and substrate (I/O Board) 2.
The DDR internal memory 12 and the FLASH flash memory 13 that are provided with master chip 11 on the core board 1 and are connected with master chip 11, DDR internal memory 12 is connected with master chip 11, and being connected of FLASH flash memory 13 and master chip 11, and is routine techniques all, does not give unnecessary details herein.In the present embodiment, master chip 11 is the little RK2918 of auspicious core; DDR internal memory 12 can be DDR2 or DDR3.
Key of the present invention is: core board 1 is arranged on the substrate 2 in disconnectable mode.Therefore, only need upgrading core board 1 can finish the upgrading of whole mainboard, shorten the upgrade cycle of mainboard; Core board can share, and can satisfy disparity items to the different requirements of mainboard as long as be equipped with different core boards, thereby economize on resources.
The above is preferred embodiment of the present invention only, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
