Along with development of wireless communication devices, particularly increasing high-speed radiocommunication access network such as HSDPA (high speed downlink packet access technology) in the global range in recent years, HSUPA (high-speed uplink packet access technique) etc. obtains commercialization, the height of notebook computer is popularized, the whole world increasing user begin to insert HSDPA by notebook, advanced persons' such as HSUPA wireless network carries out mobile Internet access, be used for the various external interface (PCMCIA of notebook, Express, USB etc.) MODEM that MODEM product has obtained the favor, particularly USB interface that are used for has obtained rapid growth; Along with USB flash disk Mobile Storage Function MSF easily, USB flash disk has obtained rapidly popularizing in the world, develop USB MODEM product and not only can satisfy the demand that is used for mobile Internet access, also can satisfy the needs of user's mobile storage simultaneously, make things convenient for the consumer greatly with USB flash disk function.
Be used at present to realize that the method that USB MODEM has a USB flash disk function mainly contains two kinds: a kind of is directly to enlarge being used on the USB MODEM to store the FLASH chip capacity of USB MODEM program etc., by software FLASH is gone up remaining space and be mapped as USB flash disk, be used as USB flash disk for the user and use; Another kind is the memory interface that utilizes the master controller (CPU) on the USB MODEM, expands the FLASH chip that USB flash disk uses separately, will be mapped as USB flash disk for the FLASH chip that USB flash disk expands by software.
Because existing implementation method all is that the FLASH space of shining upon unnecessary capacity by software is a USB flash disk, use unusual complexity on software is realized for the user; The FLASH that is used for USB flash disk simultaneously is program storage or the direct interface USB MODEM master controller that directly utilizes USB MODEM, and to the demands for higher performance of FLASH, the cost of FLASH is very high.
Therefore, need a kind of solution of modulator-demodulator of integrated memory device, can solve the problem in the above-mentioned correlation technique.
Summary of the invention
The present invention is intended to overcome the software that exists in the prior art and realizes complexity, and problem and defectives such as FLASH performance requirement height, cost height provide a kind of USB flash disk and USB MODEM function independent, realize the method and apparatus of high capacity U disc on USB MODEM.
According to the present invention, a kind of modulator-demodulator of integrated memory device is provided, comprise modem module, the modulator-demodulator of this integrated memory device also comprises: storage device is used to store data; Hub module is used for modulator-demodulator and storage device are connected to interface module; And interface module, be used for hub module is connected to external equipment.
Modulator-demodulator and storage device all are connected to hub module by USB interface.
Hub module is connected to interface module by USB interface.
Interface module is connected to external equipment by USB interface with hub module.
In this device, storage device and modulator-demodulator work alone, and storage device comprises USB flash disk.
Adopt device of the present invention, compared with prior art, introduced USB HUB (usb hub) module, realized separating fully of USB flash disk and USB MODEM, simplified the realization of software, the USB flash disk module can be used the design of present maturation, reduced design difficulty, jumbo USB flash disk function can obtain low-cost realization fast simultaneously, and the development difficulty and the development cost of having saved software have improved software stability and versatility.
Other features and advantages of the present invention will be set forth in the following description, and, partly from specification, become apparent, perhaps understand by implementing the present invention.Purpose of the present invention and other advantages can realize and obtain by specifically noted structure in the specification of being write, claims and accompanying drawing.
