Embodiment
See also Fig. 1 and Fig. 2, Fig. 1 is that in an embodiment of the present invention, electronic installation 1 is connected the schematic diagram that (PCI) device 2 connects with peripheral cell.This electronic installation 1 comprises pci interface 10, processing unit 20, first memory 30 and second memory 40.
Wherein, this first memory 30 is solidified with Basic Input or Output System (BIOS) 100.This first memory 30 can be EEPROM(Electrically Erasable Programmable Read only Memory, electricallyerasable ROM (EEROM)), this Basic Input or Output System (BIOS) 100 is solidified mode in EEPROM with existing identical, therefore do not repeat at this.
This pci interface 10 is for connecting at least one PCI device 2, and this pci interface 10 comprises some PCI pin P1 ~ Pn.This processing unit 20, for being connected with this pci interface, for when pci interface 10 is connected with PCI device 2, carries out data transmission by pci interface 10 and PCI device 2, and moves this Basic Input or Output System (BIOS) 100 when electronic installation 1 is opened.
In this second memory 40, store a register value and PCI arranges mapping table Tab1, this register value from corresponding relation table definition has been set the different corresponding PCI of register value arrange.
When electronic installation 1 starting up, these Basic Input or Output System (BIOS) 100 these pci interfaces 10 of scanning judge whether to have connected PCI device 2, and determining while having connected PCI device 2, judge and in PCI device 2, whether store a register value, if had, this Basic Input or Output System (BIOS) 100 reads the register value of this PCI device 2.This Basic Input or Output System (BIOS) 100 and according to the register value of storage in this second memory 40 with mapping table Tab1 be set determine PCI corresponding to this register value reading setting, and arrange accordingly the pin P1 ~ Pn of pci interface 10 being arranged according to this PCI.Wherein, in the present embodiment, this PCI device 2 that stores register value comprises a register 21, in this register 21, has write in advance this register value, and this register value has represented the quantity of the PCI device 2 that connects this pci interface 10 and the number of pins of each PCI device 2.
Concrete, this Basic Input or Output System (BIOS) 100 arranges the pin of corresponding pci interface 10 is set to according to this PCI: the pin P1 ~ Pn of pci interface 10 is configured to the many group PCI pin identical with PCI device 2 quantity, and the pin number that each group PCI pin comprises is identical with the pin number of each PCI device 2, each pinout of organizing pci interface reconfigures and corresponding with PCI device 2.Thereby, pin and this at least one PCI device 2 after processing unit 20 redefines by this pci interface 10 are communicated.
For example, as shown in Figure 1, if the number of pins of pci interface 10 is 16 pins, when if the number of pins of this PCI device 2 is 8 pin, in the register 21 of this PCI device 2, store register value 0208 as shown in Figure 2, the PCI device 2 that represents this pci interface 10 of connection is 2, and the number of pins of each PCI device 2 is 8.This Basic Input or Output System (BIOS) 100 scans after PCI device 2, according to register value and PCI, the PCI that mapping table Tab1 determines that register value 0208 is corresponding is set and is set to arrange 2, thereby each pin that 2 pairs of pci interfaces 10 is set according to this is configured.Concrete, this Basic Input or Output System (BIOS) 100 is divided into two groups of pins by the pin of this pci interface 10, and every group of pin number be 8, corresponding with these 2 PCI devices 2 respectively.
Wherein, the number of pins sum of all PCI devices 2 that this pci interface 10 connects equates with the number of pins of this pci interface 10, also can be less than the number of pins of this pci interface 10.For example, establishing this PCI device 2 is the device of 4 pins, and this pci interface 10 is the device of 16 pins, and this pci interface 10 can only connect PCI device 2 devices of two 4 pins, or connects the PCI device 2 of 44 pins simultaneously.
As shown in Figure 3, in the second embodiment, this pci interface 10 also comprises a serial ports pin I2C, the pin of the pci interface 10 of a connection in the PCI device 2 that this pci interface 10 connects comprises this serial ports pin I2C, and this input-output system 100 is by the register value in the register 21 of the serial ports pin I2C acquisition PCI device 2 of pci interface 10.Obviously, this input-output system 100 is by the register value in the register 21 of any pin acquisition PCI device 2 in the pin P1~Pn of pci interface 10.
This pci interface 10 comprises common pci interface, PCI-E(PCI Express, high-speed PCI) interface, the renewal version of PCIX(the pci bus that connects) interface etc.This PCI device 2 can be GPU card (Graphics Processing Unit card), multimedia card etc.
Wherein, this electronic installation 1 can be the computers such as desktop computer, notebook computer, panel computer, also can have for digital photo frame, e-book, mobile phone, digital camera etc. the electronic installation of pci interface.
PCI device 2(peripheral cell coupling arrangement of the present invention) and there is pci interface 10(peripheral cell connecting interface) electronic installation 1, can automatically change the configuration of pci interface 10 pins according to connected PCI device 2, and without Basic Input or Output System (BIOS) 100 is carried out to manual customization.
