Embodiment Construction

[0028] The present invention adopts a PCI-E bridge that can be operated in normal mode (Normal-Operation Mode) and pass-through mode (Pass-Through Mode). When the PCI-E bridge detects that the user has inserted two graphics cards, the The invented PCI-E bridge will operate in the normal mode, and the data sent by the north bridge chip will still be transmitted to the first PCI-E slot and the second PCI-E slot through the transmission channel provided by the PCI-E bridge. and when the computer system detects that the user only has a graphics card plugged in, the PCI-E bridge of the present invention will operate in a straight-through mode, and the data sent by the Northbridge chip will no longer pass through the PCI-E bridge. The provided transmission channel is directly forwarded to the PCI-E slot where the graphics card is inserted. Of course, the present invention does not limit the data sent by the north bridge chip, and it can also be the data sent by the south bridge chip...

Abstract

The present invention provides a computer system controlling data access by a bridge, including a bridge, including a transmission channel and a controller, the controller controls the transmission channel; a first slot, having a first specific foot connected to the controller; and a second slot, having a second specific foot connected to the controller. When the first slot and the second slot arecombined with a first element and a second element at the same time, the first specific foot and the second specific foot ensure the controller, ensuring a data access to the first element and the second element by a transmission channel; when only the first slot is combined with the first element, the data is directly accessed to the first element. The computer system controlling data access bythe bridge avoids the reduce of the transmission efficiency caused by the latency of the transmission channel, and avoiding the increase of the cost and the area occupying the host plate caused by theQ switch.

Description

technical field [0001] The present invention relates to a computer system, in particular to a computer system bridge with a peripheral component interconnect express (PCI-E for short hereinafter) port. Background technique [0002] see figure 1 , which shows a schematic diagram of the architecture of a computer system chipset (taking the Intel P35 platform as an example). The computer system chipset architecture mainly includes: a central processing unit 11 (Central Processing Unit, CPU), a north bridge chip 13 (North Bridge), and a south bridge chip 15 (South Bridge); The bridge chip 15 has an ICH9 structure, and the north bridge chip 13 and the south bridge chip 15 form a chipset. [0003] Such as figure 1 As shown, the northbridge chip 13 is connected to high-speed peripheral devices, including the central processing unit 11 (CPU), memory 17 (Memory) and display chip 19 . Basically, the north bridge chip 13 can be regarded as a collection of channels, and there are de...
