The beneficial effects of the utility model are: the utility model adopts storage card as program storage, and its memory space is large, simple in structure, and can greatly reduce the cost of product.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Description of drawings
Fig. 1 is the utility model system block diagram.
Fig. 2 is the utility model vice processing module section circuit theory diagrams.
Embodiment
The present embodiment is the utility model preferred implementation, and other all its principles are identical with the present embodiment or approximate with basic structure, all within the utility model protection range.
Please refer to accompanying drawing 1, the utility model adopts a kind of general jumbo storage card of controller that carries cheaply as the original non-memory loss program storage device of embedded device, substitutes the original chip such as traditional ROM, NORFLASH, NANDFLASH.in the utility model, system mainly comprises main processing block, vice processing module and be used for the memory card interface of grafting storage card, wherein, the vice processing module is connected with memory card interface, the routine interface of main processing block is connected with the vice processing module, may comprise also in system that other are as image processing module, the acoustic processing module, display module, the functional modules such as output module, do not belong to the utility model protection range, during concrete enforcement, function according to embedded system, other modules are set, other modules be connected in setting, can adopt routine techniques, repeat no more herein.In the present embodiment, it is the MCU chip of MX27 that the vice processing module adopts the model that Freescale company produces, and when specifically implementing, also can adopt other single-chip microcomputer process chip realizations.In the present embodiment, memory card interface is SD card interface, SDHC card interface, SDXC card interface, MS card interface, TF card interface, mmc card interface, sony memory block interface, XD card interface or CF card interface, can specifically select according to actual needs.
the utility model in use, under the MX27 chip platform of Freescale company, utilize model for the single-chip microcomputer of STM32 (in the present embodiment, adopting model is that the single-chip microcomputer of STM32 is as main processing block) by serial ports, the bootloader of MX27 chip is passed to the MX27 chip, then the MX27 chip moves this bootloader from MICRO-SD (TF) card (the present embodiment, take SD card or TF card as example) the inner embedded OS program that is stored in the inside that starts, thereby realized that SD card or MICRO-SD (TF) card is as the original non-memory loss program storage solution of embedded device.
The utility model adopts storage card as program storage, and its memory space is large, simple in structure, and can greatly reduce the cost of product.
