(1) PCIe expansion circuit
This PCIe expander circuit is foretell PCIe Switch, in the utility model discloses in, can adopt current Switch, Switch chip 89H32H8G2 ZCLGLI of IDT company for example, this chip has 32 Lane, 8 interfaces, can input 1 way x8PCIe interface, exports 6 way x 4PCIe interface. As shown in fig. 2.
(2) PCI conversion circuit design
The PCI conversion circuit is designed as a PCIe-to-PCI bridge, and 12 hybrid slots on a motherboard support CPCI bus communication with system slots. Because the CPCI bus is limited by the bandwidth, the routing length and other factors, each section of the 33MHz CPCI supports at most 7 peripheral slots, so 2 sections of CPCI bus need to be designed to be respectively connected with slots No. 1-6 and slots No. 7-12.
In order to implement the above solution, in the present invention, the present invention can select the chip that can be realized currently, for example, the Bridge chip XIO2001IZGUR of TI company, as shown in fig. 3, the CPCI conversion circuit is designed on the motherboard, and 2 paths of × 1PCIe buses output by the system socket are converted into 2 CPCI buses through the PCIe to PCI Bridge chip, respectively.
