Embodiment

The circuit diagram of a relevant preferred embodiment of the present utility model at first sees also shown in Figure 1ly, and it includes:

One control module 10, in present embodiment, its controller IC by numbering PNX1502 is constituted, and it possesses control, computing, translation function, and a built-in loading and unloading management process (holding the back statement);

One memory card interface administration module 20, see through pci interface and 10 bindings of aforementioned control module, in present embodiment, this memory card interface administration module 20 is made up of plural memory card controller 21, an interface controller 22 etc., each memory card controller 21 is connected with interface controller 22 respectively, and sees through interface controller 22 and control module 10 bindings;

Plural number memory card connector 30, be connected with each memory card controller 21 in the memory card interface administration module 20 respectively, and the usefulness of confession grafting memory card, this memory card connector 30 can be to be supported single specification or supports the All-in-One specification, for example, the memory card form of its support can comprise: (aforementioned memory card form are only for exemplifying non-appointment memory card form) such as CF, SD, MMC, MS and XD;

One communication interface 40, be made up of an interface controller 41 and an interface connector 42, in present embodiment, this interface connector 42 is a usb interface connector, it is connected with

interface controller

41, and 41 of this interface controllers see through pci interface and are connected with control module 10.

Can utilize control module 10 to see through the memory card of pegging graft on memory card interface administration module 20 each memory card connector 30 of scanning according to the prostatitis assembly, and undertaken by control module 10 built-in loading and unloading management processes that capacity merges or the memory card loading and unloading, when aforementioned device sees through communication interface 40 with the computing machine binding, because control module 10 has been one with the memory card capacity integration of all grafting, so be to link single Storage Media for computing machine, that is link an action hard disk or a removable hard drive.

See also shown in Figure 2 again, circuit diagram for the another preferred embodiment of the utility model, its basic framework is identical with last embodiment, difference is in the interface controller 21 of: this memory card interface administration module 20 and further connects at least one second interface connector 23, in present embodiment, this second interface connector 23 is a USB connector, when the memory card that possesses USB interface or Portable flash memory device inserted second interface connector 23, the memory headroom of this memory card or Portable flash memory device also can be merged.

And aforementioned means is except that can be an action hard disk, more can further be extended for a multi-media player, see also shown in Figure 3, mainly be to make aforementioned control module 10 further connect a display module 50, an one audio module 60 and an operation interface (not shown), for playing video-audio data, wherein, display module 50 can be a LCD, 60 of this audio modules can be by an amplifying circuit 61, one digital analog converter 62 and a loudspeaker 63 are formed, the input end of this amplifying circuit 61 sees through digital analog converter 62 and is connected with the message output terminal (Audio Out) of control module 10, the output terminal of amplifying circuit 61 then is connected with loudspeaker 63, send the voice data of digital form when the message output terminal of control module 10, promptly be converted into analog signal and deliver to amplifying circuit 61 and make processing and amplifying, play by loudspeaker 63 again by digital analog converter 62.As for operation interface can be key groups, contact panel etc., selects or carry out the control project for the user.

The concrete structure of each possible embodiments of the utility model from the above, below sincerely be described further with regard to control module 10 built-in loading and unloading management processes, be to adopt LVM (Logical Volume Management) mode to carry out logical volume (Logical Volume) management in present embodiment.LVM is compared to traditional disk space partitioning scheme, the mode that provides higher level and have more efficient is with management system disc storage space, mainly be under the situation that available data is not destroyed, to carry out the adjustment of Storage Media easily because of seeing through the logical volume that LVM set up, add fashionablely as new Storage Media, the logical volume that can immediately the space that newly adds Storage Media be incorporated into originally directly provides use.

Can understand by above-mentioned LVM method, the utility model provides the integration conversion medium that can freely load and unload memory card, control module 10 is because of built-in LVM, so except the memory card spatial integration that memory card interface administration module 20 can have been linked is the unity logic volume, add fashionable as new memory card, the space that control module 10 can utilize LVM will newly add memory card adds in the logical volume of former establishment and directly uses, in other words, create a file label if the utility model is integrated former binding memory card capacity and be Barebone and capacity is the logical volume of 4G, the memory card that possesses the 1G capacity in new adding one, then the capacity of this 1G will be through the integration of control module 10, directly incorporate into this in the Barebone logical volume, make the capacity amplification of Barebone be 5G.

Since control module 10 allows freely to expand the capacity of having created logical volume, also allow freely to reduce its capacity certainly, with regard to the utility model, promptly allow memory card to pull out, before memory card is extracted, utilize mechanism's mode or electric means to produce a unload request (Un-mount Reguest) to control module 10, after the LVM of control module 10 receives unload request and approval (Acknowledge), promptly carrying out data moves, the former data that are stored in the desire unloading memory card space are moved to memory card in the binding, can allow the memory card unloading subsequently.Thus, utilize memory card space that the utility model not only can integrate plural number or even different size so that an action hard disk to be provided, and visual actual needs expand or the space of reduction action hard disk.

When the utility model and computing machine binding, will be regarded as a removal formula disk, after yet the utility model adds audiovisual terminals equipment, promptly become the multi-media player (as MP3, MP4) of an adjustable lift face amount, the space that the user can unify to use plural memory card to merge stores video-audio data, and as described in preceding taking off, its capacity can see through the plug memory card to expand or reduction.
