Abstract
The invention provides an external accumulator system and method which can be loaded on a portable digit equipment to expand the memory storage when it is used continuously. The portable digit equipment possesses a Central Processing Unit which is used to process the data catched by input end, a control module which is used to choose storage path and a storage card which is used to store data, when the control module detects that that the portable digit equipment is loaded on a external accumulator system, the control module cuts off the communication channel to the storage card and chose the storage path of external accumulator system, the data is written to the external accumulator system to avoid that the portable digit equipment terminates the data collecting for the under-size capacity of the storage card.
Description
[Ji Intraoperative field]
Relevant a kind of external memorizer system of the present invention and method, particularly a kind of external memorizer system and method that when using portable digital equipment continuously, data is deposited in this external memorizer.
[Bei Jing Ji Intraoperative]
Now, portable digital equipment (as digital video camera DV, digital camera DC etc.) is extensively used by popular, and the data of the required storage of these portable digital equipments are quite big, when the user uses these equipment, the off-capacity of Chang Yinqi storage card, or memory card capacity is saturated and cause the situation be forced to end of using, and it needs computing machine to carry out data transmission as media, download data to another bigger data access arrangement, and then cause user's inconvenience; Though and have at present external memorizer can assist the capacity of its internal memory card of expansion, but must under the situation of this portable digital equipment shutdown, take out storage card, and then connect another external memorizer and data are read in wherein, cause like this to use and interrupt, also inconvenience is used.
[summary of the invention]
The object of the present invention is to provide a kind of external memorizer system and method, it can be stored in data on this external memorizer under the situation of uninterrupted use one portable digital equipment.
For reaching above-mentioned purpose, the present invention proposes a kind of external memorizer system, comprise a portable digital equipment and an external memorizer, and this portable digital equipment is provided with a central processing unit that is used to handle the data that load module grasps, one is used to select the control module and of store path to be used to store the storage card of data, after this control module detects this portable digital equipment loading external memorizer, this control module is cut off the communication channel that leads to storage card, and the store path of selection external memorizer, and this control module writes this external memorizer with data after the data that receive central processing unit.
External memorizer method of the present invention, this method comprises at least: whether (1) control module inquiry portable digital equipment loads external memorizer; If not, then enter (2) and select the store path of storage card; If then enter the store path that (3) select external memorizer.
After above-mentioned flow process, portable digital equipment is in running, its data sync storage in the direct communication of this portable digital equipment in external memorizer, thereby avoid this portable digital equipment because of self with the capacity too small activity that stops ongoing extracting data of storage card.
Relevant detailed content of the present invention and technology, conjunction with figs. is described as follows:
[description of drawings]
Fig. 1 is the composition block scheme of external memorizer system of the present invention.
Fig. 2 is the signal flow graph of external memorizer method of the present invention.
[embodiment]
Please refer to shown in Figure 1, shown among this figure is the composition block scheme of external memorizer system, in this system, be provided with a portable digital equipment 11, this portable digital equipment 11 is provided with a central processing unit 110, this central processing unit 110 is used to handle the raw data of load module acquisition, and the data transmission after will handling is given the buffer 112a in the control module 112, this control module 112 is used for selecting the storage route, and the data of buffer 112a after handling in order to temporary this central processing unit 110, and after control module 112 is selected paths these data of output.In the present embodiment, two storage routes are arranged: the first is connected in storage card 111, be used to store the data after this central processing unit 110 is handled, pictorial data for example, it two is to be coupled in an external memorizer 12, wherein, this control module 110 is connected with one first interface 113, and external memorizer 12 and these first interface, 113 relative one second interfaces 123 of setting up, this second interface 123 and this first interface 113 are set up communication by transmission line, are used for the data after the processing of central processing unit 110 are write external memorizer 12.
Please refer to Fig. 2, be the signal flow graph of external memorizer method of the present invention, at first, execution in step 210, whether control module 112 these portable digital equipments 11 of inquiry load external memorizer 12, and promptly whether first interface 113 sets up communication channel with second interface 123.
If do not load external memorizer 12, then execution in step 220, and control module 112 is selected first store path, promptly selects storage card 111; Then, execution in step 230, whether control module 112 inquiry central processing units 110 need to store data, if not, then repeating step 230, if, then execution in step 240, and data write storage card 111 after entering the buffer 112a of control module 112 from central processing unit 110 again.
If load external memorizer 12, then execution in step 250, and control module 112 is selected second store path, promptly selects external memorizer 12; Then, execution in step 260, whether control module 112 inquiry central processing units 110 need to store data, if not, then repeating step 260, if then execution in step 270, after data enter the buffer 112a of control module 112 from central processing unit 110, write external memorizer 12 by control module 111, first interface 113 and second interface 123 successively again.
Therefore, according to external memorizer system provided by the present invention and method, can be under the situation of uninterrupted use one portable digital equipment 11, deposit data in an external memorizer 12, thus avoid this portable digital equipment 11 because of self with the too small activity that stops ongoing extracting data of capacity of storage card 111.
