Patent Issued for Computer System with Bridge

September 11, 2014



By a News Reporter-Staff News Editor at Computer Weekly News -- According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventors Huang, Pai-Ching (Taipei, TW); Hung, Tsung-Fu (Taipei, TW), filed on December 23, 2010, was published online on August 26, 2014.

The assignee for this patent, patent number 8819324, is ASUSTeK Computer Inc. (Taipei, TW).

Reporters obtained the following quote from the background information supplied by the inventors: "The invention relates to a computer system and, more particularly, to a computer system with a bridge.

"At present, Intel and Advanced Micro Device (AMD) are central processing unit (CPU) manufactures having the highest market shares. Taking a computer system with the Intel CPU as an example, the south bridge and the north bridge communicate with the peripheral device via a peripheral component interconnect express (PCIe) bus, and data is transferred between the north bridge and the south bridge via a direct media interface (DMI) bus.

"FIG. 1 and FIG. 2 are block diagrams showing a conventional computer system 100 and a conventional computer system 200. The computer system 100 and the computer system 200 include a main memory module 110, a CPU 120, a north bridge 130, a south bridge 140, and two slots 150 and 160, respectively. The CPU 120 is used for controlling the operations of the computer system 100 and the computer system 200, such as executing a software program, processing or calculating the data. The north bridge 130 is electrically connected to the main memory module 110 via a memory bus, it is electrically connected to the CPU 120 via a CPU bus, and it is electrically connected to the slot 150 via a PCIe bus. The slot 150 may insert a high speed expansion device (such as a graphic card), and the north bridge 130 controls the high speed communication between the main memory module 110, the CPU 120, an image sub-system, and the PCIe bus. The slot 160 may insert a low speed peripheral device (such as a hard disk control card, an universal serial bus (USB) control card, a 1394 control card, an optical disc drive (ODD), an audio card, a network card), and the peripheral device is electrically connected to the south bridge 140 via a PCIe bus. Then, the south bridge 140 processes the input and output function of the computer systems 100 and 200. On the other hand, the north bridge 130 includes a DMI output controller, and the south bridge 140 includes a DMI input controller. The data are transferred between the north bridge 130 and the south bridge 140 via four channels of the DMI bus.

"In the conventional computer system 100, the slot 150 includes a group of PCIe x16 slots which may support a graphic card. After a display device (such as a screen) is connected to the graphic card, the images of the computer system 100 are outputted. In the conventional computer system 200, the slot 150 includes two PCIe x8 slots, which can support two graphic cards. With the parallel image processing method, the graphic processing per second of each graphic card can be added up, and thus the efficiency of the image processing system is improved.

"However, in the present computer system, the image processing system performing advanced graphic calculations requires a higher speed, which cannot be met by the conventional computer systems 100 and 200."

In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "The invention provides a computer system including a central processing unit (CPU), a north bridge, a bridge, a south bridge and a slot. The north bridge is electrically connected to the CPU. The bridge is connected to the north bridge and the south bridge for adjusting the output bandwidth of the first data and the second data and generating a corresponding first data and a second data according to a channel control signal transmitted from the north bridge. The south bridge is electrically connected to the bridge to receive the first data. The slot is electrically connected to the bridge to receive the second data and exchanging the data with the north bridge via the bridge.

"These and other features, aspects and advantages of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings."
