Description
Technical field
The present invention relates to a kind of concentrator control chip, particularly a kind of integrated-type usb hub control chip.
Background technology
In recent years, fast development along with science and technology, 3C Product makes rapid progress, various computer-related products constantly come out like the mushrooms after rain, and also constantly evolution of employed transmission technology between host side and the device end, but, be widely used most and still adopt the transmission technology of USB to carry out the binding of peripheral device and host computer system than the transmission mode of tool stability from present.And the USB transmission technology has not only been developed maturation and simplicity of design, more meets the requirement of most of peripheral devices on speed, becomes at present the transmission mode that main product standard lift-launch is on the market used.
Yet, because personal computer is limited for providing of usb connecting port, especially mobile computer, not only the port number that can support on the script motherboard is fixed, in appearance design, must consider simultaneously whole size again, therefore the quantity that provides of usb connecting port just has been provided more.
In addition, because the consumer is for the requirement of product function, it is multi-functional integrated and emphasize that it is supportive to cause now the product of development and Design all must be particular about, to increase consumer's buying motive, for example: additionally arrange in pairs or groups in early days disc driver, pcmcia interface or CD-ROM drive etc. of mobile computer are the outfits that belongs to complete; But mobile computer now must be equipped with various Radio Transmission Technologys (as infrared ray, bluetooth etc.), silicon disk machine or even digital camera etc. especially to increase competitiveness of product.Yet from the above, if various peripheral devices adopt the USB transmission technology to design, be built in the mobile computer in the control chip with each peripheral device, not only can take the circuit space on the motherboard, also can cause the available USB port quantity of motherboard residue to reduce simultaneously.
For head it off, see also Fig. 1, use the mainboard module synoptic diagram of usb hub framework for prior art, as shown in the figure, under condition based on the USB specification, concentrator control chip 10a includes one first uplink port 101a to be used for connecting i/o controller line concentration unit (the I/O Controller Hub that motherboard 1a itself is provided, ICH claims south bridge again) 20a and carried out communication, and concentrator control chip 10a comprises a plurality of first downlink port 102a simultaneously being used for connecting the second uplink port 301a among the peripheral control chip 30a respectively, and also comprises the running of port controller (Port Controller) (not shown) with control uplink port and downlink port in above-mentioned each uplink port and downlink port respectively.Reach bridge joint i/o controller line concentration unit 20a and peripheral control chip 30a by this and carry out the purpose of data transmission.
Though this settling mode can overcome the problem that takies the USB port that motherboard 1a i/o controller line concentration unit 20a provided, not only each peripheral control chip 30a does not reduce, and the necessary circuit space that increases concentrator control chip 10a, make the space that takies motherboard 1a effectively to dwindle.Moreover, owing to still carry out communication among concentrator control chip 10a and each the peripheral control chip 30a by uplink port and downlink port, and wherein all must design the ports having controller respectively to control the running of each uplink port and downlink port, therefore increase the cost burden on the hardware design on the contrary.
Summary of the invention
In view of this, technical matters to be solved by this invention is, utilize the sharable characteristic of hardware circuit, carry out concentrator control chip and a plurality of peripheral device control chip integrated, with the uplink port (containing port controller) that saves each peripheral control chip, and can vacate the downlink port of concentrator control chip and offer other circumscribed USB peripheral device simultaneously with USB port that script motherboard i/o controller line concentration unit is had and use.By this, not only can save circuit space, the minimizing hardware cost of motherboard, more can reach the versatility of increase concentrator control chip and the purpose of extendibility.
In order to address the above problem, according to a kind of scheme proposed by the invention, a kind of integration type concentrator control chip is provided, this concentrator control chip is the universal serial bus concentrator control chip, be applied to the motherboard of an application system, it comprises: a uplink port transmission unit, a uplink port control module, a trunk unit, a Keyboard Control module, a digital photography control module, a medium control module and a trunk control module.Wherein, the uplink port transmission unit is in order to connect i/o controller line concentration unit (the I/O Controller Hub that motherboard provided, ICH), and the data transfer direction that uplink port control module control uplink port transmission unit is transmitted, moreover, the trunk unit electrically connects the uplink port control module, and provides at least one transmission path for data transmission.This trunk unit comprises: a transponder, for this trunk control module when these control modules and this uplink port transmission unit switch by identical traffic speed the transmission path of use; And a transfer interpreter, when being different transmission speed with this uplink port transmission unit, these control modules switch the transmission path of use for this trunk control module.In addition, Keyboard Control module, digital photography control module and medium control module then are used to provide respectively to application system and connect a key-press matrix, an image-finding element and at least one card connector, at last, switch the transmission path of relay transmission unit by the trunk control module that electrically connects the trunk unit according to uplink port transmission unit and data rate that above-mentioned these control modules operated again, to meet this i/o controller line concentration unit and the mutual data transmission of these control modules.
