Embodiment
The main thought that the present invention is based on the serial ports control automatic switchover of heterogeneous multi-core system is: set this system monitoring nuclear, utilize internuclear communication mode monitoring serial port to connect the state of nuclear by this monitoring nuclear, when serial ports connection nuclear state was unusual, the process that serial ports control is automaticallyed switch was finished in control.
Heterogeneous multi-core system of the present invention comprises that monitoring nuclear, serial ports connect nuclear and preparation nuclear, adopts internuclear communication mode to carry out interacting message between each nuclear, wherein,
Serial ports connects nuclear and is used for the control system serial ports, and regularly authorizes to monitoring by internuclear communication mode and to send state to report message, and sends out handoff request outside to the monitoring consideration convey;
Discern for ease of monitoring nuclear, serial ports connection nuclear adopts the message format of arranging in advance to authorize to monitoring and send state report message.
Monitoring nuclear is used for being connected the nuclear agreement with serial ports and reports time out period, and be used to judge that serial ports connects authorizes whether send state to report message overtime, if when overtime or the outside handoff request of receiving that serial ports connects that consideration convey sends out, also be used for by the control of internuclear communication mode notice preparation stone grafting pipe serial ports, and determine whether to select for use other nuclears to carry out serial ports control switching as preparation nuclear according to the handoff response situation that preparation is examined.
Preparation nuclear is that monitoring nuclear is selected or determine according to outside handoff request from the free time nuclear (being the current nuclear of not controlling serial ports) of system, is used to take over the control to system's serial ports, and to monitoring nuclear feedback switching response message.
The serial ports control automatic switching method that the present invention is based on above heterogeneous multi-core system may further comprise the steps:
Steps A: monitoring nuclear is connected the connection of nuclear agreement serial ports and authorizes the report time out period that send state report message with serial ports;
Step B: serial ports connects nuclear and utilizes internuclear communication mode regularly to report message to monitoring nuclear transmission state in reporting time out period, if receive outside handover request message, then sends out handover request message outside to the monitoring consideration convey;
Step C: connect and authorize the state that send to report message overtime or receive that serial ports connects the outside that consideration convey sends out and switches the serial ports request message if existing serial ports is authorized in monitoring, monitoring nuclear selects other idle nuclears to determine preparation nuclear as preparation nuclear or according to outside handoff request;
Step D: monitoring nuclear is authorized to preparation and is sent serial ports handoff request message, and preparation stone grafting pipe is to the control of serial ports, and authorizes to monitoring according to switching result and to send the serial ports switching request response, finishes serial ports control and automaticallyes switch.

Outside switching request response module: be used for receiving serial ports and connect the outside handover request that consideration convey is sent out, and judge whether handover request nuclear is monitoring nuclear itself, switches if then stop, and switches otherwise call the automatic switchover control module.
The serial ports control switching that the present invention triggers outside handover request is also adopted by monitoring nuclear and is controlled, and can prevent because of the handover request dyskaryosis, and hang up phenomenon after the switching that causes.
Below in conjunction with accompanying drawing, the workflow of above each module and serial ports of the present invention control automatic switching method are elaborated.
Monitoring module
Monitoring module can be realized by the following method to the monitoring that current serial ports connects nuclear: connect nuclear by current serial ports and regularly report information to monitoring nuclear transmission state by internuclear communication mode, if the state that monitoring module is received in time out period current " serial ports connects nuclear " is reported information, then with timer zero clearing, reclocking.Otherwise, if timer expiry is not received the state of " serial ports connects nuclear " as yet and is reported information, it is unusual to think that then current " serial ports connect nuclear " taken place when operation, then can call the automatic switchover control module and attempt switching serial ports and control on other nuclears in the system.
The software flow pattern that each clock of monitoring module interrupts is as shown in Figure 2:
Step 201: judge whether timer is overtime, if call the automatic switchover control module; Otherwise change step 202
Step 202: judge whether to receive message from " serial ports connects nuclear ".If change step 3, otherwise change step 205
Step 203: the message format of arranging in advance according to both sides judges whether it is that state is reported message, if change step 204, otherwise change step 205;
Internuclear communication is the universal means of multi-core CPU, reports message except the state of the present invention definition, may also have other to use also by internuclear communication transmission of information between a plurality of nuclears, so will be distinguished in the system.
Step 204: monitoring module finishes this flow process with the timer zero clearing;
Step 205: monitoring module adds 1 with timer, finishes this flow process, namely continues the state of monitoring serial port connection nuclear in this time out period.
The automatic switchover control module
After monitoring module concludes that current " serial ports connects nuclear " taken place unusually, another one nuclear in the automatic switchover control module selective system (being called preparation nuclear) is as the nuclear of prepare control serial ports, and to preparation nuclear transmission handover request message, if it is normal to prepare the state of nuclear, can take over voluntarily serial ports after then receiving message, and everything is ready, and the message of feedback serial ports handover success is examined in the back monitoring, if prepare nuclear serial ports handoff failure, then examines the message that sends a handoff failure to monitoring.The timer that the automatic switchover control module is deleted after receiving the feedback message of handover success former " serial ports connection nuclear " is examined establishment and is started new timer for preparation simultaneously, calls then monitoring module and monitors that again this new serial ports connects nuclear.If instead the preparation nuclear state of selecting is also undesired, can't normally take over serial ports or feedback information, other nuclears that the serial ports handover module reselects in the system are examined as preparation, and repeat said process.
The workflow of this automatic switchover control module may further comprise the steps as shown in Figure 3:
Step 301: from system, select a preparation nuclear, if switched by the serial ports control that outside handover request triggers, then be to determine preparation nuclear according to handover request, if chosen successfully, turn to step 302, if there is not selectable preparation nuclear, conclude that then all nuclears are all unusual in the current system, abandon automaticallying switch;
More than said preparation nuclear refer to that the non-serial ports of normal operation connects nuclear, the free time nuclear in the system can be ranked according to the emergency of respectively checking the serial ports demand for control by system in advance as the order of preparation nuclear.
Step 302: send handover request message to preparation nuclear, and wait for the handover request ack message of preparation nuclear, if wait timeout (can set in advance feedback time) turns to step 301, otherwise turns to step 303;
The nuclear of setting preparation in advance feedback time can prevent because of the preparation nuclear state unusual, can't feed back handover request ack message, waits as long for and cause monitoring to examine.
Step 303: analyze feedback message, switch the serial ports success if message shows preparation nuclear, turn to step 304, otherwise turn to step 301;
Step 304: delete former timer, and be the new timer of preparation nuclear establishment;
Step 305: call monitoring module and begin to monitor current serial ports connection nuclear preparation nuclear.
Outside switching request response module
When the outside sent to current " connecting serial ports nuclear " switching serial ports request by serial ports after, " serial ports connects nuclear " transmitted this request and examines for monitoring.
2) automatic switchover control module adopts the flow process as Fig. 4:
The outside serial ports handoff response module of monitoring nuclear adopts the flow process such as Fig. 3:
Step 401: judge whether to receive the switching serial ports request message of transmitting from current " serial ports connects nuclear ", if, change step 402, otherwise process ends;
Step 402: analyze message and judge whether the nuclear of request switching is monitoring nuclear itself.If change step 403; Otherwise change step 404;
Step 403: stop the message of switching to current " serial ports connects nuclear " feedback;
Step 404: call " automatic switchover control module ".
More than forever can not describe as example as " serial ports connect nuclear " to monitor nuclear itself, normal condition does not have the request that switches to monitoring nuclear, but in order to prevent maloperation, so receiving, monitoring nuclear needs to judge whether request switches is to monitor nuclear itself after this request, if it is feedback stops the message of switching, otherwise call " automatic switchover control module ", the message of switching to " serial ports connects nuclear " feedback permission simultaneously, on the other hand, current " connecting serial ports nuclear " if receive the feedback message that stops switching, then abandons this switching; If receive the message that allows switching, then initiatively abandon it to the control of serial ports.
If in actual applications, nuclear in the heterogeneous multi-core system all might be called serial ports and connect nuclear, then can solve by the method for setting " preparation monitoring nuclear ", if promptly need to connect nuclear as next serial ports by current monitoring nuclear according to external command, then call " preparation monitoring nuclear " and monitor current monitoring nuclear, realize the present invention.
Compared with prior art, heterogeneous multi-core system of the present invention and automatic based on the serial ports control of this system Changing method, this kind of means of communication is the most direct between utilization nuclear, and most effective mode realizes oneself of serial ports The moving switching, and the transmission state is reported the automatic detection CPU of message when connecting nuclear and appraise and decide to monitoring by serial ports Abnormality, do not introduce other outside hardware modules, in case it is unusual to find that serial ports connects nuclear, can Carry out immediately the automatic switching of serial ports control, prevent serial ports control hang-up.
