Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 2 is the synoptic diagram that the present invention is based on the interrupt processing system of interrupt nesting, described interrupt processing system 100 is applied in the SOC system, the interrupt source that comprises interrupt handler 10 and some various priority, the priority of interrupt source is consistent with the priority of the interrupt request that described interrupt source is sent, be provided with at least one interrupt counter 20 in described each interrupt source, wherein:
Interrupt handler 10, be used to handle the current interrupt request of current interrupt source, and in the current interrupt request process of handling current interrupt source, if receive other interrupt request of other interrupt sources of high priority, then interrupt current interrupt request, other interrupt request of handling high priority are returned and are handled current interrupt request until finishing; If do not receive other interrupt request of other interrupt sources of high priority, then continue to handle current interrupt request until disposing.
Preferably, during interrupt processing system 100 initialization, the interrupt counter 20 of interrupt source is by zero setting.
Be more preferably, the interrupt source of various priority is respectively equipped with register 30, is preferably the readable register of writing 30, is used to store the priority and the corresponding saturation value thereof of current interrupt source, and this saturation value can dispose its size according to user's request.Especially, the saturation value of the interrupt counter 20 of interrupt source can be corresponding with its priority, and the saturation value of different priority can be different, can certainly be identical.And after if the priority of current interrupt source changes, the saturation value of the interrupt counter 20 of current interrupt source is corresponding with the priority after the change.
With respect to traditional interrupt nesting method, interrupt processing system 100 of the present invention has all added an interrupt counter 20 for each interrupt source, be used for statistics in current interrupt request processing procedure, the number of times that this current interrupt request is interrupted, the priority of these interrupt counter 20 corresponding current interrupt request has a saturation value in advance, register 30 is preserved the size of this saturation value, if during interrupt counter 20 values of reaching capacity size, can temporarily improve the priority of this current interrupt source in inside, make it wait until Interrupt Process.So also can in interrupting application process, control the priority of interrupt request indirectly, make that the controllability of processed of interrupt request is stronger.Thereby the present invention has solved well in the low interrupt request of interrupt nesting medium priority and can not get the problem handled for a long time, effectively raises the efficient that the SOC system handles is interrupted.
Fig. 3 is the process flow diagram that the present invention is based on the interruption processing method of interrupt nesting, this interruption processing method is applied in the SOC system, the interrupt source of various priority is respectively equipped with interrupt counter 20, each interrupt counter 20 is provided with saturation value, described interruption processing method can realize by interrupt processing system 100 as shown in Figure 2, comprises that at least step is as follows:
Step S301, handle in the current interrupt request process of current interrupt source,, then interrupt current interrupt request if receive other interrupt request of other interrupt sources of high priority, otherwise continue to handle current interrupt request until disposing, this step can be realized by interrupt handler 10.
Step S302, the current interrupt request of interrupt counter 20 statistics of current interrupt source is interrupted number of times by what other interrupt request of high priority interrupted, if interrupt the saturation value that number of times equals interrupt counter 20, then the priority with current interrupt source raises, at this moment the priority of current interrupt request has also just raise, and this step can be realized by interrupt counter 20.Preferably, the interrupt source of various priority is respectively equipped with register 30, and register 30 is used to store the priority and the corresponding saturation value thereof of current interrupt source.And the saturation value of the interrupt counter 20 of interrupt source can be corresponding with its priority.After the priority of current interrupt source changed, the saturation value of the interrupt counter 20 of current interrupt source was corresponding with the priority after the change.
Step S303, other interrupt request of handling high priority are returned this current interrupt request of processing until finishing, and this step can be realized by interrupt handler 10.
Fig. 4 be in the preferred embodiment of the present invention based on the process flow diagram of the interruption processing method of interrupt nesting, it can be realized by interrupt processing system 100 as shown in Figure 2, comprise that step is as follows:
Step S401, interrupt processing system 100 is in idle state (IDLE), and promptly interrupt processing system 100 is in the state of not receiving interrupt request.Preferably, during initialization, the interrupt counter 20 of interrupt source is by zero setting.
Step S402, if receive the current interrupt request of current interrupt source, execution in step S403 then, otherwise return step S401.
Step S403 handles this current interrupt request.Be the interrupt service routine that interrupt processing system 100 can enter this current interrupt request, begin to handle current interrupt request.
Step S404, in the process of handling this current interrupt request, if receive other interrupt request of other interrupt sources, judge whether the priority of other interrupt request is higher than the priority of current interrupt request, be the priority whether priority of other interrupt sources is higher than current interrupt source, if the priority that the priority of other interrupt request is higher than current interrupt request is execution in step S405 then, if the priority of other interrupt request is less than or equal to the priority of current interrupt request, then execution in step S410 promptly continues to handle current interrupt request.
Step S405, interrupt processing system 100 interrupts current interrupt request, and the interrupt counter 20 of this current interrupt source is added 1.
Step S406, whether the interrupt counter 20 of judging current interrupt source the value of reaching capacity, if execution in step S407 then, otherwise execution in step S408.
Step S407, if the value of reaching capacity, then with 1 grade of the temporary transient rising of the priority of current interrupt source, and with interrupt counter 20 zero clearings of current interrupt source.If the current interrupt request that this priority is low is repeatedly broken, then the interrupt counter 20 of this current interrupt source may the value of reaching capacity, the priority of this current interrupt request can be enhanced 1 grade so, so not by may just having increased that other interrupt request of high priority interrupt.
Step S408, interrupt processing system 100 is handled other interrupt request of high priority.
Step S409, other interrupt request of high priority dispose, and return step S404, the current interrupt request of the low priority before promptly handling.
Step S410 continues to handle current interrupt request until finishing.
Step S411 judges whether the priority of current interrupt source changes, if change then execution in step S412, otherwise returns the idle state of step S401 after interrupt counter 20 zero clearings with current interrupt source.
Step S412 returns to initial value (priority before promptly raising) with the priority of current interrupt source, and returns the idle state of step S401 after interrupt counter 20 zero clearings with current interrupt source.
Interrupt processing system 100 with a priority from 0 to 7 is an example below, and the limit priority of this interrupt processing system 100 is 7, and lowest priority is 0, and from 0 to 7 priority increases gradually.Table (a) has shown pairing priority of each interrupt request and saturation value thereof.
Table (a)
| Interrupt source | a | b | c | d | e | f | g | h |
| Priority | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| The interrupt counter saturation value | 6 | 5 | 5 | 5 | 5 | 3 | 3 | 2 |
From table (a), can find out that the saturation value of the interrupt counter 20 of interrupt source is corresponding with its priority.The priority of interrupt source a is minimum, and the saturation value of its corresponding interrupt counter 20 is 6, and the priority of interrupt source h is the highest, and the saturation value of its interrupt counter 20 is 2.
When beginning most, interrupt source a sends an interrupt request a, interrupt processing system 100 begins to enter the interrupt service routine of interrupt request a, this moment, other interrupt sources were also sent other interrupt request, interrupt request a can't obtain in a period of time handling, and the mode of interrupt processing system 100 handling interrupt requests is shown in table (b).
Table (b)
As can be seen, the break in service that constantly has other interrupt request of high priority to interrupt interrupt source a is at first handled, when each interrupt request a is interrupted, the interrupt counter a value of interrupt source a all adds 1, when interrupting counter a value of reaching capacity 6, the internal priority of the interrupt source a one-level that temporarily raises, become 1 by 0, when NextState, interrupt source b send interrupt request b, because the priority of interrupt source b is the same with the priority of interrupt source a, so interrupt request a processing is no longer interrupted and obtains to handle, after the interrupt request a of interrupt source a finished dealing with, interrupt processing system 100 judged whether the priority of interrupt source a is consistent with initial priority, because initial priority is 0, current priority is 1, so the priority of interrupt source a is changed to 0, and, returns idle state with the interrupt counter a zero clearing of interrupt source a.
After if interrupt source a priority is upgraded to 1, still being higher than other interrupt request (for example interrupt request e of interrupt source e) of 1 by priority interrupts continuously, interrupt source a also can be after the saturation value that satisfies next interrupt counter a so, further its priority of rising is till the interrupt request a of interrupt source a is processed.Be pointed out that, after the priority of interrupt source a changes, the saturation value of interrupt counter a with change after priority corresponding, for example after the priority of interrupt source a is upgraded to 2, the saturation value of interrupt counter a is corresponding with priority 25.
In sum, the present invention is on the interrupt nesting basis of SOC system, added internal priority growth function, promptly each interrupt source in the interrupt processing system is added an interrupt counter, this interrupt counter can be added up current interrupt request in processing procedure, the number of times that is interrupted continuously by other interrupt request of high priority; If the low current interrupt request of priority is repeatedly interrupted, then the interrupt counter of this current interrupt source may reach predetermined saturation value, can temporarily improve the priority of described current interrupt source so in inside, the possibility that makes the current interrupt request of current interrupt source of low priority obtain Interrupt Process increases.The invention solves the problem that the low priority interrupt request can't obtain handling for a long time, thereby improved the Interrupt Process efficient of SOC system.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
