Wherein, when when the first master control set 22 and the second master control set 24, one of them wants access interface device 26, e.g. by universal input output (the General Purpose Input/Output being not used by coffret, GPIO) labelling that stitch records in checking the buffer 268 of interface arrangement 26, and the data link between the first master control set 22 and the second master control set 24 another and interface arrangement 26 wherein closed according to this, and start interface arrangement 26 to carry out data access.
Particularly, Fig. 3 is the method for managing power supply flow chart of system of the support dual master control device access interface device shown by first embodiment of the invention.Refer to Fig. 3, the method for managing power supply of the present embodiment is applicable to the every assembly in the system 20 of above-described embodiment, the most i.e. combined system 20, and the detailed step of method for managing power supply is described:
When the first master control set 22 and the second master control set 24, one of them wants access interface device 26, can first check the labelling of record in the buffer 268 of interface arrangement 26, and the data link between another device and the interface arrangement 26 in the first master control set 22 and the second master control set 24 closed according to this, and start interface arrangement 26 to carry out data access (step S302).Wherein, the first master control set 22 and the second master control set 24 are if recovering the operational mode of interface arrangement 26 to normal operation mode to carry out data access.
On the other hand, when the first master control set 22 or the second master control set 24 stop access interface device 26, the labelling of record in the buffer 268 of interface arrangement 26 can be revised as unmanned use, and control interface arrangement 26 and enter operation phase " shut " mode" (step S304), to wait access next time.Wherein, first master control set 22 and the second master control set 24 are if using the control platform architecture in above-mentioned Fig. 1, and control interface arrangement 26 by the platform control unit (not shown) of itself and enter operation phase " shut " mode", or recovered to normal operation mode by operation phase " shut " mode".
It should be noted that, the mark zone of record in the buffer 268 of interface arrangement 26 is divided into logical zero 0 to represent unmanned use by the present embodiment further；Logical zero 1 represents the first master control set and uses；Logic 11 represents the second master control set and uses；Logic 10 represents the second master control set and uses but the first master control set preferentially uses etc. four kinds, and is available for the first master control set 22 and the second master control set 24 accesses to determine subsequent action.Wherein, the labelling kind corresponding to above-mentioned logical signal by way of example only, and is not limited to this.
When the first master control set 22 wants access interface device 26, what if it was checked is labeled as unmanned use (i.e. logical zero 0), labelling then can be revised as the first master control set 22 and use (i.e. logical zero 1), and the operational mode of interface arrangement 26 is recovered to normal operation mode, carry out data access with docking port device 26；And when the second master control set 24 wants access interface device 26, what if it was checked is labeled as unmanned use (i.e. logical zero 0), labelling then can be revised as the second master control set 24 and use (i.e. logic 11), and the operational mode of interface arrangement 26 is recovered to normal operation mode, carry out data access with docking port device 26.
It should be noted that, the present embodiment also can define the privilege of access power of the first master control set 22 and the second master control set 24 further so that the privilege of access power of the first master control set 22 is higher than the second master control set 24.Accordingly, when the first master control set 22 or the second master control set 24 want the data of access interface device 26, if interface arrangement 26 is unmanned uses (i.e. logical zero 0), then can directly wake up interface arrangement 26 up to carry out data access；If interface arrangement 26 has been used (i.e. logical zero 1 or 11), then can compare privilege of access power further, to determine still to be carried out data access by the second master control set 24 docking port device 26 by the first master control set 22.
For example, Fig. 4 is the state machine diagram of disappointed first master control set shown by first embodiment of the invention, and Fig. 5 is the state machine diagram of the second master control set shown by first embodiment of the invention.Wherein, the privilege of access power of the first master control set is higher than the second master control set.Please also refer to Fig. 4, the state machine 40 of the present embodiment the first master control set 22 be applicable to above-described embodiment.First, when the first master control set 22 wants access interface device (i.e. having activity), and when needing to be recovered to normal operation mode (D0) operational mode of interface arrangement 26 by operation phase " shut " mode" (RTD3), i.e. enter the flow process on Fig. 4 left side, by the labelling of record in the buffer 268 of the first master control set 22 access interface device 26.
Wherein, when being labeled as of being checked is unmanned use (i.e. logical zero 0) or the first master control set to use (i.e. logical zero 1) time, this labelling can be revised as the first master control set and use (i.e. logical zero 1) by the first master control set 22, thus the operational mode of interface arrangement 26 is recovered to normal operation mode (D1) by operation phase " shut " mode" (RTD3), so that it is carried out data access；When checked be labeled as second master control set use (i.e. logic 11) time, this labelling can be revised as the second master control set and use but the first master control set preferentially uses (i.e. logic 10) by the first master control set 22, its right to use is given back the first master control set 22 controlling interface arrangement 26；When checked be labeled as second master control set use but the first master control set preferentially use (i.e. logic 10) time, then represent interface arrangement 26 and not yet the right to use is given back the first master control set 22, now the first master control set 22 can continue check mark again, during until the right to use is given back the first master control set 22 by interface arrangement 26, labelling just can be revised as the first master control set and use (i.e. logical zero 1), thus the operational mode of interface arrangement 26 is recovered to normal operation mode (D0) by operation phase " shut " mode" (RTD3), to carry out data access.Wherein, recover to normal operation mode (D0) at interface arrangement 26, and when being carried out data access by the first master control set 22, first master control set 22 can persistently judge whether this access action terminates, if access action still continuously active, then interface arrangement 26 is maintained normal operation mode (D0)；If access action is stopped action, then enter the flow process on the right of Fig. 4.
When the first master control set 22 stops access interface device (i.e. not having activity), and when needing that the operational mode of interface arrangement 26 is switched to operation phase " shut " mode" (RTD3) by normal operation mode (D0), the flow process on the right of Fig. 4 can be entered, by the labelling of record in the buffer 268 of the first master control set 22 access interface device 26.Wherein, when being labeled as of being checked is unmanned use (i.e. logical zero 0) or the second master control set to use (i.e. logic 11) time, the operational mode of interface arrangement 26 can be switched to operation phase " shut " mode" (RTD3) by normal operation mode (D0) by the first master control set 22；When checked be labeled as first master control set use (i.e. logical zero 1) time, labelling can be revised as unmanned use (i.e. logical zero 0) by the first master control set 22, and by normal operation mode (D1), the operational mode of interface arrangement 26 is switched to operation phase " shut " mode" (RTD3)；When checked be labeled as second master control set use but the first master control set preferentially use (i.e. logic 10) time, labelling can be revised as the second master control set and use (i.e. logic 11) by the first master control set 22, and by normal operation mode (D1), the operational mode of interface arrangement 26 is switched to operation phase " shut " mode" (RTD3).Wherein, when interface arrangement 26 switches to operation phase " shut " mode" (RTD3), first master control set 22 can persistently determine whether access action, if there is no access action (i.e. not having activity), then interface arrangement 26 is maintained operation phase " shut " mode" (RTD3), if and have other access action (i.e. having activity), then enter Fig. 4 left side flow process.
Then, refer to Fig. 5, the state machine 50 of the present embodiment is applicable to second master control set 24 of above-described embodiment.First, when the second master control set 24 wants access interface device 26 (i.e. having activity), and when needing to be recovered to normal operation mode (D0) operational mode of interface arrangement 26 by operation phase " shut " mode" (RTD3), i.e. can enter the flow process on Fig. 5 left side, by the labelling of record in the buffer 268 of the second master control set 24 access interface device 26.Wherein, when being labeled as of being checked is unmanned use (i.e. logical zero 0) or the second master control set to use (i.e. logic 11) time, this labelling can be revised as the second master control set and use (i.e. logic 11) by the second master control set 24, thus the operational mode of interface arrangement 26 is recovered to normal operation mode (D1) by operation phase " shut " mode" (RTD3), so that it is carried out data access；When first master control set that is labeled as checked uses (i.e. logical zero 1) or the second master control set to use but time the first master control set preferentially uses (i.e. logic 10), i.e. represent the first master control set 22 to be currently in use, and owing to the privilege of access of the first master control set 22 is weighed higher than the second master control set 24, therefore the second master control set 24 can continue check mark, until the first master control set 22 stops access interface device 26, and the labelling of interface arrangement 26 by the first master control set 22 be revised as unmanned use (i.e. logical zero 0) time, this labelling is just revised as the second master control set and uses (i.e. logic 11) by the second master control set 24, thus the operational mode of interface arrangement 26 is recovered to normal operation mode (D1) by operation phase " shut " mode" (RTD3), so that it is carried out data access.Wherein, recover to normal operation mode (D0) at interface arrangement 26, and when being carried out data access by the second master control set 24, second master control set 24 can persistently judge whether this access action terminates, if access action still continuously active, then interface arrangement 26 is maintained normal operation mode (D0)；If access action is stopped action, then enter the flow process on the right of Fig. 5.
When the second master control set 24 stops access interface device 26 (i.e. not having activity), and when needing that the operational mode of interface arrangement 26 is switched to operation phase " shut " mode" (RTD3) by normal operation mode (D0), the flow process on the right of Fig. 5 can be entered, by the labelling of record in the buffer 268 of the second master control set 24 access interface device 26.Wherein, when being labeled as of being checked is unmanned use (i.e. logical zero 0) or the first master control set to use (i.e. logical zero 1) time, the operational mode of interface arrangement 26 can be switched to operation phase " shut " mode" (RTD3) by normal operation mode (D0) by the second master control set 24；When second master control set that is labeled as checked uses but time the first master control set preferentially uses (i.e. logic 10) or the second master control set to use (i.e. logic 11), labelling can be revised as unmanned use (i.e. logical zero 0) by the second master control set 24, and by normal operation mode (D1), the operational mode of interface arrangement 26 is switched to operation phase " shut " mode" (RTD3).Wherein, when controlling interface arrangement 26 and switching to operation phase " shut " mode" (RTD3), second master control set 24 can persistently determine whether access action, if there is no access action (i.e. not having activity), then interface arrangement 26 is maintained operation phase " shut " mode" (RTD3), if and have other access action (i.e. having activity), then enter Fig. 5 left side flow process.
By said system and method, first master control set 22 and the second master control set 24 can be according to each other for the access actions of interface arrangement 26, decision will the operational mode of how switching interface 26, thus reach the present invention and support dual master control device access same-interface device and save effect of electric power.
It should be noted that, in the above-described embodiments, be serially connected between the first master control set 22 and the second master control set 24 only has an interface arrangement 26.And in other embodiments, multiple interface arrangement between the first master control set 22 with the second master control set 24, also can be concatenated, and the first master control set 22 and the second master control set 24 are also that the same way using above-mentioned access interface device 26 is to access these interface arrangements.
In addition, above-described embodiment is used for concatenating coffret e.g. universal serial bus (Universal Serial Bus, USB) 3.0 interfaces or thunderbolt (Thunderbolt) interface of first master control set the 22, second master control set 24 and interface arrangement 26.If use thunderbolt interface concatenate, the present invention also can further by two data transmission channels of thunderbolt interface all for transmitting data so that first master control set the 22, second master control set 24 and interface arrangement 26 can support that two-channel data are transmitted.Hereinafter describe in detail for an embodiment the most again.
