Description
[technical field]
The invention relates to a kind of line carrier plate, and particularly relevant for a kind of motherboard.
[background technology]
At present general motherboard all has several PCI slots, and these PCI slots mainly are to be used for carrying out with peripheral device the transmission or the exchange of data.Present CPU (central processing unit) (central processing unit, frequency of operation CPU) is up to more than the 1GHz, however the frequency range of pci bus has only 133Mb/s.In other words, the transmission speed of data still is subject to the frequency range of pci bus.In addition, with regard to the wires design of motherboard, important circuit for example is that pulse signal transmission line and data line are principle to walk around the PCI slot as far as possible all, and therefore when increasing the quantity of PCI slot for expanding system usefulness, the area that can connect up on the motherboard also just dwindles.In other words, the degree of difficulty of the wires design of motherboard also just increases.
[summary of the invention]
In view of this, purpose of the present invention is providing a kind of motherboard exactly, and it has the more area that can connect up.
Based on above-mentioned purpose, the present invention proposes a kind of motherboard, and it comprises a plurality of chipsets, one first line carrier plate, one first slot, one second slot and one second line carrier plate, and wherein these chipset configuration are on first line carrier plate.First slot and second slot configuration are on first line carrier plate, and first slot and second slot are at a distance of a gap (gap).In addition, second line carrier plate is embedded simultaneously to first slot and second slot, and second line carrier plate is electrically connected to first line carrier plate via first slot and second slot.
According to preferred embodiment of the present invention, above-mentioned motherboard more comprises one the 3rd slot, and it is disposed on first line carrier plate, and the 3rd slot accord with PCI specification.
According to preferred embodiment of the present invention, above-mentioned motherboard more comprises one the 4th slot and a tertiary circuit support plate, wherein the 4th slot configuration is on second line carrier plate, and the tertiary circuit support plate is embedded to the 4th slot, and the tertiary circuit support plate is electrically connected to second line carrier plate via the 4th slot.In addition, the 4th slot for example is accord with PCI specification or accord with PCI-express specification.
According to preferred embodiment of the present invention, the first above-mentioned slot and second slot accord with PCI-express specification.
Based on above-mentioned, because line carrier plate is embedded simultaneously to first slot and second slot, and first slot and second slot gap apart, so motherboard of the present invention has the more area that can connect up.In other words, the wires design of motherboard of the present invention has bigger elasticity.
For making purpose of the present invention, structural attitude and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:
[description of drawings]
Figure 1A and Figure 1B illustrate the synoptic diagram of the motherboard of first embodiment of the invention.
Fig. 2 A and Fig. 2 B illustrate the synoptic diagram of the motherboard of second embodiment of the invention.
[embodiment]
[first embodiment]
Figure 1A and Figure 1B illustrate the synoptic diagram of the motherboard of first embodiment of the invention and ask simultaneously with reference to Figure 1A and Figure 1B, the motherboard 100 of present embodiment comprises one first line carrier plate 110, one first slot 112, one second slot 114, one the 3rd slot 116, one second line carrier plate 120 and a plurality of chipsets 130, and wherein these chipsets 130 are disposed on first line carrier plate 110.For example, these chipsets for example are processor chip set, memory chip group, north bridge chipset (North Bridge) and South Bridge chip group (SouthBridge) etc., wherein South Bridge chip group (South Bridge) mainly is responsible for connecting interface of peripheral device, and these interfaces include bus, hard disk and various output and input media etc.
More specifically, the PCI-express slot can be divided into 1x (36 contact), 4x (64 contact), 8x (98 contact) and 16x different sizes such as (164 contacts) again, and has big or small rough the equating of PCI-express slot with the PCI slot with 98 contacts of 168 contacts.In addition, the PCI-express slot for example is to be applied in chip to chip (chip to chip), core bus (backplane bus) and this local bus (local bus) etc.
It should be noted that, owing to all have compatibility between the PCI-express slot of different size, therefore just can be embedded simultaneously to the first slot l12 and second slot 114 through second line carrier plate 120 after the design, and first slot 112 and second slot 114 clearance G apart again.In other words, the important signal line of part just can pass through clearance G, and must not change the wire laying mode of adopting coiling, and therefore motherboard 100 of the present invention has the more area that can connect up.
Compared to prior art, each contact of PCI-express slot can provide the high-speed transfer frequency range of 2.5Gbps, and the PCI-express slot is to adopt point-to-point connected mode when transmission, therefore motherboard 100 of the present invention not only has preferable electrical property efficiency, has more comparatively stable transmission quality and transmission speed.In addition, compared to the existing PCI slot that uses, the cost of PCI-express slot is lower, and therefore motherboard 100 of the present invention has the advantage on the cost.
Please continue with reference to Figure 1A, motherboard 100 does not limit only has accord with PCI-first slot 112 and second slot 114 of express specification, and motherboard 100 more comprises having one the 3rd slot 116, it is disposed on first line carrier plate 110, and the 3rd slot 116 accord with PCI specifications or other specification.
[second embodiment]
Fig. 2 A and Fig. 2 B illustrate the synoptic diagram of the motherboard of second embodiment of the invention.Please be simultaneously with reference to Fig. 2 A and Fig. 2 B, second embodiment is similar to first embodiment, its difference is: motherboard 200 more comprises one the 4th slot 222 and a tertiary circuit support plate 230, wherein the 4th slot 222 is disposed on second line carrier plate 220, and the combination of second line carrier plate 220 and the 4th slot 222 for example is the expansion board (riser card) of switching usefulness.In addition, tertiary circuit support plate 230 is embedded to the 4th slot 222, and tertiary circuit support plate 230 is electrically connected to second line carrier plate 220 via the 4th slot 222.For example, tertiary circuit support plate 230 for example is the adapter of drafting card, network card or various kenels, and the 4th slot 222 accord with PCI specifications or PCI-express specification.
What deserves to be mentioned is, because each contact of PCI-express slot can provide the high-speed transfer frequency range of 2.5Gbps, therefore on second line carrier plate 220, do not limit and only dispose single slot, also can on second line carrier plate 220, dispose the PCI or the PCI-express slot of right quantity, so that expand the usefulness of motherboard 200.In addition, in a second embodiment, first line carrier plate 210 for example is backboard (backplane), and first line carrier plate 210 also can be applied among first embodiment.
In sum, motherboard of the present invention has following advantages at least:
One, be embedded simultaneously to first slot and second slot owing to line carrier plate (adapter or adapter), And first slot and second slot be at a distance of a gap, so signal line just can pass through this gap G, and need not advance Row coiling design. In other words, motherboard of the present invention not only has the more area that can connect up, and this The wires design of bright motherboard has more bigger elasticity.
Two, use the PCI slot compared to prior art, motherboard of the present invention not only have better electrically Usefulness has more comparatively stable transmission quality and transmission speed.
