Abstract
The present invention discloses a method for generating virtual storage space on a hand electronic device. A control software is arranged in a computer device, a driving program of a virtual device is arranged on a hand electronic device, wherein the hand electronic device is provided with a file system filter which is arranged between a kernel program and a driving program of a storage device. In a normal state, an instruction of the kernel program is directly transferred to the file system by the file system filter, and data of the file system are transferred to the kernel program by the file system filter. When an instruction which is transferred by the control software on the computer device is received by the virtual driving program, the file system filter is required to change the direction, and thus, the instruction comes from the kernel program is transferred to the driving program of the virtual device, the instruction is transferred to the computer device by the driving program of the virtual device, the subsequent processing of the instruction is carried out by the control software on the computer device, desired data are transferred back to the kernel program via the driving program of the virtual device and the file system filter, and thereby, a storage media (or a file directory in the storage media) of the computer device is virtualized into the storage device on the hand electronic device.
Description
[technical field]
The present invention is about a kind of method for producing virtual storage space of hand electronic device, this method makes this hand-hold electronic device be connected with a computer equipment, so as to by suitable steering order with change the mechanism, with with the Storage Media on this computer equipment virtual be storage facilities on this hand-hold electronic device, so, can significantly promote the storage area of this hand-hold electronic device.
[background technology]
Personal digital assistant (Personal Digital Assistant, be called for short PDA), former the design's target is personal organiser (Personal Information Management, be called for short PIM), for example, basic functions such as the record management of individual's time-histories, notepad, telephone directory, be called electronics hand account (organizer) again, but in the communication and the arriving in computer integration epoch, PDA not only possesses outside the basic functions, more emphasize integrating speech sound and wireless transmission capability, make PDA Upgrade Now and be the much-sought-after item of 3C.
PDA is compared to other portable information product, it integrates personal information management and digital communication ability, make PDA in numerous products, show one's talent, compared to notebook computer, though PDA on information processing rate far away from notebook computer, but PDA has better portability, for example be in harmony public occasion outside, carry 2 kilograms the notebook computer of weighing, start will wait a long time, might not find grid line (or telephone wire) online again, its expensive price allows the people draw back especially, can't fully reach the boundary of " anytime; anywhere ", and PDA not only build is petite is easy to carry about with one, but also can be linked on the Internet by wave point at any time, no wonder liked by many business people.
PDA now no longer is simple " hand-hold electronic device ", but the combination of personal digital assistant and " radio modem ", make its transmitting-receiving Email that not only can surf the Net, read news, download company information, transmitting outside the notebook computer of success, other creates separating of a portable product.
Compact build: desirable mobile digital instrument, should be as carry-on memo pad, can singlehandedly grasp, easy to carry, even in the pocket of can packing into and do not dislike burdensome, the build of present PDA is mostly as the little notebook of picture, weight about about 100 g, very light.
Generally speaking, the PDA that each manufacturer developed and designed now need possess following advantage:
(1) microprocessor of RISC framework: the PDA processor that is different from PC is emphasized speed, and the processor low-cost for PDA, that conformability is high and power consumption is low just really is fit to it, and therefore, RISC is on the contrary than being more suitable for that CISC framework common in the computer comes.
(2) firm shatter-proof anti-falling: because PDA is often taken away in bringing on hand by the people, therefore shatter-proof and anti-falling to a certain degree must be arranged, therefore the storage device of PDA will be avoided the mechanical type framework of hard disk and so on, and must provide firm framework with static memory (DRAM), internal memory (flash RAM), read-only internal memory (ROM) or the original papers such as memory card of PCMCIA specification.
(3) starting up speed is fast: this requirement is the emphasis in the PDA exploitation specification originally, if you can imagine that PDA pulls open two or three minutes on the confidential grade as computer one, just nobody will be with it for that, because nobody can be ready to accept the wait of several minutes embarrassments.
(4) the long and smart province of power consumption of stand-by time:, can take at any time, rather than usually not have electricity to miss many good opportunities in order to allow PDA be in best state.PDA must be to the general long-time standby ability of other mobile phone, therefore at present usually to use the alkaline battery of standard specification.
(5) be input as the master with touch: PDA uses for convenience, generally all adopts handwritten input method, as long as take pen to put picture one picture in order, can operate it very easily, and this is for the people of many complicated using method that do not coomputerate, and the threshold of can saying so is much lower.The input mode of keyboard is not suitable for PDA, and it is one that keyboard volume can't narrow down to that PDA requires, the hand-held body be unfavorable for keyboard operation be its two, so handwritten input method meets the input method of PDA kenel most.
Developing, (for example: PDA, Smart Phone testing or keeping in repair various hand-hold electronic devices ... Deng) time, often need the device on install software or archives, but all restrictions of Chang Yinwei and failing, or the storage area deficiency on the device, or storage facilities can't operate, and makes operating personnel waste many times on install software.
Therefore, if can there be a kind of method passable, so as to increasing the quality of conversation the tinkle of bells, so design concept is deeply convinced for the manufacturer of vast consumption masses and mobile phone, is a doulbe-sides' victory situation in fact.
[summary of the invention]
