About aforementioned and other technology contents, characteristics and effect of the present invention, in the detailed description below in conjunction with reference to the accompanying drawings a preferred embodiment, can clearly present.
Consult Fig. 1, the preferred embodiment of the communication system of capable of adjusting consumed power of the present invention is applicable to receive a line message, comprises one first R-T unit 11, one second R-T unit 12, a reception interface 13 and a Fabric Interface 14.Each R-T unit 11,12 comprises respectively a transmission end 111,121 and one receiving terminal 112,122, and the first R-T unit 11 also comprises a leading-in end 113.And the relation that couples of each element as shown in Figure 1.
The enforcement aspect of this preferred embodiment for example is, the operation of the first R-T unit 11 is to be relevant to the PHY layer, and the operation of the second R-T unit 12 is to be relevant to the MAC layer, and reception interface 13 is optical fiber (fiber) interface, and Fabric Interface 14 is the SerDes interface.But the aspect of practical application is not limited to this, reception interface 13 also can be unshielded twisted pair (Unshielded Twisted Pair is called for short UTP) interface, and Fabric Interface 14 also can be medium independent interface (Media Independent Interface, be called for short MII), or other.
Consult Fig. 1 and Fig. 3, communication system 1,3 mode of operation mainly are divided into two large classes: aggressive mode, Passive Mode.When the pattern of having the initiative (such as Fig. 1), communication system 1 is whether the leading-in end 113 according to the first R-T unit 11 receives the line message, decides this R-T unit 11,12 power supply status, and then changes communication contact to each other.When being in Passive Mode (such as Fig. 3), communication system 3 more is applicable to receive an external command from an external device, and determines according to this this R-T unit 11,12 power supply status, and then changes communication contact.Wherein, power supply status can be done switching between power supply state and power down mode.In order more specifically to describe the transformation of power supply status, specially enumerate three examples at this aggressive mode is described, and enumerate two examples Passive Mode is described.
Aggressive mode
Example one: at initial time, all power supply statuss are all power supply state.
Do not have the line message to import into by reception interface 13 until leading-in end 113 is discovered, the first R-T unit 11 just switches to power down mode with transmission end 111 and receiving terminal 112, also therefore causes the receiving terminal 122 that does not have message to import the second R-T unit 12 into.So the second R-T unit 12 also makes transmission end 121 and receiving terminal 122 switch to power down mode.At this moment, this R-T unit 11,12 can't carry out communication.
Then, until discovering, leading-in end 113 have the line message to import into by reception interface 13, the first R-T unit 11 just switches to power supply state again with transmission end 111 and receiving terminal 112, this will have message to import into so that the second R-T unit 12 is discovered because of receiving terminal 122, and make transmission end 121 and receiving terminal 122 all switch to power supply state.At this moment, this R-T unit 11,12 can carry out communication by Fabric Interface 14, correctly to receive and dispatch message.
Example two: see also Fig. 2, communication device 2 also comprises a monitoring interface 25, makes the second R-T unit 12 can know at any time the operative scenario of the first R-T unit 11.At initial time, all power supply statuss are all power supply state.
Do not have the line message to import into until leading-in end 113 is discovered, the first R-T unit 11 just switches to power down mode with transmission end 111 and receiving terminal 112.Then, the second R-T unit 12 knows that by monitoring interface 25 the first R-T unit 11 is in power down mode, and makes transmission end 121 and receiving terminal 122 switch to power down mode.
Then, have the line message to import into until leading-in end 113 is discovered, the first R-T unit 11 just switches to power supply state with transmission end 111 and receiving terminal 112.Then, the second R-T unit 12 knows that by monitoring interface 25 the first R-T unit 11 is in power supply state, and makes transmission end 121 and receiving terminal 122 switch to power supply state.
This example also can be that the second R-T unit 12 knows by monitoring interface 25 whether leading-in end 113 receives the line message and decide.
Example three: see also Fig. 2, communication device 2 also comprises a monitoring interface 25, makes the second R-T unit 12 can order the first R-T unit 11 to enter which power supply status.At initial time, all power supply statuss are all power supply state.
When the order of the second R-T unit 12 enters power down mode, the first R-T unit 11 makes transmission end 111 and receiving terminal 112 switch to power down mode, and the second R-T unit 12 also makes transmission end 121 and receiving terminal 122 switch to power down mode.
When the order of the second R-T unit 12 enters power supply state, the first R-T unit 11 makes transmission end 111 and receiving terminal 112 switch to power supply state, and the second R-T unit 12 also makes transmission end 121 and receiving terminal 122 switch to power supply state.
And, in this example, this transmission end 111,121 and receiving terminal 112,122 Switching power change order can arrange arbitrarily.
Passive Mode
Example one: see also Fig. 3, at initial time, all power supply statuss are all power supply state.
When the external command that receives required the first R-T unit 11 to switch to power down mode, the first R-T unit 11 made transmission end 111 and receiving terminal 112 all switch to power down mode.Then, the second R-T unit 12 knows that by monitoring interface 25 the first R-T unit 11 is in power down mode, and makes transmission end 121 and receiving terminal 122 switch to power down mode.
In like manner, when the external command that receives required the first R-T unit 11 to switch to power supply state, all power supply statuss of the first R-T unit 11 and the second R-T unit 12 all switched to power supply state.Wherein, whether the power supply status how the second R-T unit 12 switches transmission end 121 and receiving terminal 122 also can be to have message to import into and decide according to receiving terminal 122, might not need by monitoring interface 25.
Example two: see also Fig. 4, at initial time, all power supply statuss are all power supply state.
When the external command that receives required the second R-T unit 12 to switch to power down mode, the second R-T unit 12 made transmission end 121 and receiving terminal 122 all switch to power down mode.Then, the first R-T unit 11 knows that by monitoring interface 25 the second R-T unit 12 is in power down mode, and makes transmission end 111 and receiving terminal 112 switch to power down mode.
In like manner, when the external command that receives required the second R-T unit 12 to switch to power supply state, all power supply statuss of the second R-T unit 12 and the first R-T unit 11 all switched to power supply state.And also can omit monitoring interface 25, and whether be had message to import into to decide the power supply status of transmission end 111 and receiving terminal 112 by the first R-T unit 11 according to receiving terminal 112.
But no matter communication device 1~4 is in any pattern, application example should not be subject to above-mentioned the announcement.And power down mode can refer to powered-down, can refer to that also power consumption is far below power supply state, for example: be 1/10 power of power supply state.Wherein, for the receiving terminal 122 of the second R-T unit 12, power down mode being set as low-power, whether have message import, to wake at any time (wake-up) second R-T unit 12 up if can continue to observe.In like manner, for the receiving terminal 112 and leading-in end 113 of the first R-T unit 11, power down mode being set as low-power, whether have message import, to wake at any time the first R-T unit 11 up if can continue to observe.
