Embodiment Construction

[0011] Below in conjunction with accompanying drawing and preferred embodiment the present invention is described in further detail:

[0012] Please refer to Figure 1 to Figure 3 The interface transmission device 100 of the present invention includes a master controller 10, a master connector U0 connected to the master controller 10, first to fourth slave connectors U1-U4 and first to fourth control switches S1-S4, each A control switch is correspondingly connected with a slave connector. In this embodiment, the first master connector U0 and each slave connector are Peripheral Component Interconnect Express (PCIE). The main controller 10 is a platform controller (Platform Controller Hub, PCH).

[0013] The first control switch S1 to the fourth control switch are connected to the main controller 10 in series in order to receive the data signal transmitted by the main control, that is, the first control switch S1 is connected to the main controller 10, and the second control ...

Abstract

An interface transmission device includes a controller, a principal connector, a plurality of subordinate connectors, and a plurality of switches with same numbers as those of the subordinate connectors. Each switch is connected to a subordinate connector. A logical address of each switch is different. The controller can exchange data with a PCIE card through the principal connector, or through one of the subordinate connectors according to a logical address of a switch.

Description

technical field [0001] The invention relates to an interface transmission device of a server. Background technique [0002] In the server, there are usually multiple peripheral device quick connection interfaces (Peripheral Component Interconnect Express, PCIE) on the motherboard, which can be used to connect PCIE function cards such as graphics cards to improve processing capabilities. However, at present, the PCIE interfaces of server motherboards are serially connected to the main controller by using the same SMBus bus. Usually, there are multiple PCIE interfaces on the motherboard, and each PCIE interface is connected to a PCIE function card. A PCIE interface corresponding to the PCIE function card causes the main controller to fail to read the data of the PCIE function card normally. Contents of the invention [0003] In view of the above, it is necessary to provide an interface transmission device that enables each connector connected to the main controller to have...
