Fig. 2 is the structural representation of the utility model portable computer mainboard second embodiment.
Embodiment
Describe below in conjunction with the structure of accompanying drawing the utility model portable computer mainboard.
Seeing also Fig. 1, is the first embodiment structural representation of portable computer mainboard of the present utility model.Described portable computer mainboard 1 comprises one first a fen plate 11 and an interface arrangement 12.
Described cpu socket 111 is in order to the configuration central processing unit.Described cpu socket 111 couples with described north bridge chips 113.Described South Bridge chip 115 couples with described north bridge chips 113.Described quarter stuff 13, described the 3rd minute plate 15 and described panel 17 couple with described South Bridge chip 115 respectively.
Described north bridge chips 113 is also referred to as main bridge (Host Bridge), be responsible for and the getting in touch of CPU, and control internal memory (figure do not show), figure go out processor data such as (figure do not show) in the north bridge internal transmission, and type and supports such as dominant frequency, type of memory and max cap. to CPU are provided.Described north bridge chips 113 is general to be provided with near described cpu sockets 111, the closest because north bridge chips 113 and CPU directly communicate by letter, and shortens transmission range in order to improve communication performance.In addition, the data processing amount of described north bridge chips 113 is very big, and thermal value is also increasing, generally speaking, is covered with one deck heat radiator (figure does not show) on described north bridge chips 113.
Described South Bridge chip 115 is coupled in described north bridge chips 113, carries out uploading and assigning of signal with north bridge chips 113.Described South Bridge chip 115 is generally from cpu socket 111 below far away of the mainboard 1 of described portable computer.More with the I/O bus that described South Bridge chip 115 is connected, it is arranged on described cpu socket 111 belows far away helps wiring.Described South Bridge chip 115 does not generally all cover heat radiator, because the data volume that it is handled generally is not very big.
Described quarter stuff 13, described the 3rd minute plate 15 and described panel 17 all couple with described South Bridge chip 115.Described quarter stuff 13 comprise a network interface card interface 131 and a network interface card I/O chip for driving 133; Plate 15 comprised a card reader interface 151 and a card reader I/O chip for driving 153 in described the 3rd minute; Described panel 17 comprises a USB (universal serial bus) 171 and a USB (universal serial bus) I/O chip for driving 173.
