Abstract
The utility model relates to a universal serial bus (USB) diskless drive unit, which comprises a processor, a UBS connector, memories and a memory switching circuit. The memories consist of a drive code memory with drive codes inside and an equipment execution code memory with equipment execution codes inside. The drive code memory and the equipment execution code memory are respectively connected with the memory switching circuit. The drive code memory, the equipment execution code memory and the memory switching circuit are respectively connected with the processor, or the drive code memory and the equipment execution code memory are respectively connected with the processor through the memory switching circuit. The USB diskless drive unit has the advantages that since one memory switching circuit and one drive code memory are added, the intra-product integration of a USB drive is realized, the installation of the USB drive is automatically executed after the USB diskless drive unit is inserted into a personal computer (PC), a separate installation disk is not required to be equipped and the USB diskless drive unit is very convenient.
Description
Technical field
The utility model relates to a kind of USB drive unit, and particularly disclosing a kind of USB does not have disk drive device.
Background technology
At present, along with the extensive utilization of USB, increasing electronic product uses USB as its PORT COM.But a lot of electronic equipments all needs to install USB and drives when using for the first time.All can attach a USB drive installation dish in a lot of electronic products that the user buys,, thereby after product inserts PC, will not be identified and to use if there is not such mounting disc.And many times we can not carry such mounting disc when using electronic equipment, at this moment will cause the user experience of product very poor, and the cost of CD are than higher.Therefore be badly in need of a kind of convenience, implementation cheaply.
Summary of the invention
The purpose of this utility model is to overcome the defective that exists in the prior art, and the product that provides a kind of USB of realization to drive is interior integrated, need not to be equipped with independent mounting disc, and USB easy to use does not have disk drive device.
The utility model is achieved in that a kind of USB does not have disk drive device, comprise processor, USB connector, storer, it is characterized in that: also comprise the storer commutation circuit, described storer is formed by being provided with the equipment run time version storer that is provided with the equipment run time version in the driving code memory, that drives code in one; Described driving code memory, equipment run time version storer link to each other with the storer commutation circuit respectively, and described driving code memory, equipment run time version storer, storer commutation circuit link to each other with processor respectively; Or described driving code memory, equipment run time version storer link to each other with processor by the storer commutation circuit respectively.
Described processor is provided with parallel interface or serial line interface.
The excuse of described storer is parallel bus or universal serial bus.
Described storer commutation circuit is according to control mode, can divide into two kinds: the one, the chip selection signal of control store, the memory bus of processor is except chip selection signal at this moment, the all direct signal wire with two storeies of other signal wires links together, chip selection signal then is connected on the storage-selection circuit, determines by processor control store commutation circuit which storer this chip selection signal is connected to; The 2nd, the mode of all memory buss of processor controls, in this manner, all signal wires of the memory bus of processor all are connected on the storer commutation circuit, by processor control store commutation circuit memory bus are connected on the storer of expectation.
The beneficial effects of the utility model are: drive code memory by increasing a storer commutation circuit and, the product of realizing the USB driving is interior integrated, after the utility model inserts PC, automatically perform the installation that USB drives, do not need like this to be equipped with independent mounting disc, very convenient.
Description of drawings
Fig. 1 is the structured flowchart of the utility model connected mode one.
Fig. 2 is the structured flowchart of the utility model connected mode two.
Embodiment
According to Fig. 1, Fig. 2, the utility model comprises processor, USB connector, storer, storer commutation circuit, and described storer is formed by being provided with the equipment run time version storer that is provided with the equipment run time version in the driving code memory, that drives code in one.Described driving code memory, equipment run time version storer link to each other with the storer commutation circuit respectively, and described driving code memory, equipment run time version storer, storer commutation circuit link to each other with processor respectively; Or described driving code memory, equipment run time version storer link to each other with processor by the storer commutation circuit respectively.Described processor is provided with parallel interface or serial line interface.The excuse of described storer is parallel bus or universal serial bus.
Connected mode one: according to above-mentioned syndeton, when described driving code memory, equipment run time version storer links to each other with the storer commutation circuit respectively, described driving code memory, equipment run time version storer, when the storer commutation circuit links to each other with processor respectively, the control mode of storer commutation circuit is: the mode of the chip selection signal of control store, the memory bus of processor is except chip selection signal at this moment, the all direct signal wire with two storeies of other signal wires links together, chip selection signal then is connected on the storage-selection circuit, determine by processor control store commutation circuit which storer this chip selection signal is connected to, as Fig. 1.
Connected mode two: when described driving code memory, equipment run time version storer link to each other with processor by the storer commutation circuit respectively, the control mode of storer commutation circuit is: the mode of all memory buss of processor controls, in this manner, all signal wires of the memory bus of processor all are connected on the storer commutation circuit, by processor control store commutation circuit memory bus is connected on the storer of expectation, as Fig. 2.
Under default situations, processor control store commutation circuit connects the memory signals bus of processor and equipment run time version storer, like this, when device power was started shooting, the processor slave unit run time version storer program of reading was carried out and is realized start.If this moment USB connector is connected to the USB port of PC, processor is by the USB communication of USB connector and PC so, whether processor can detect PC at this moment has installation USB of the present utility model to drive, if processor detects the driving that USB of the present utility model is not installed on the PC, processor control store commutation circuit then, the memory bus of processor is connected with the driving code memory of depositing USB driving run time version, processor just can read USB and drive run time version so, and on PC, carry out, this moment, the interface of PC can recognize a CD drive of operation automatically, eject USB and drive the process of installing automatically, realize the installation that USB drives.
After installation, processor meeting control store commutation circuit switches to equipment run time version storer with the memory bus of processor, processor is shaken hands once more by the USB of USB connector and PC, at this moment, the equipment of USB driving successfully is installed on PC then can have been discerned by PC.
