Embodiment two
The present embodiment is secondary to a kind of interruption based on variable priority proposed by the present invention on the basis of the above embodiments
Sanction method describes in detail.This method comprises:
S201, the mapping relations one by one for interrupting physical message and interrupt logic information are established.
It should be noted that each functional module interrupts according to interrupt condition generation interruption and goes out originating party using level in system
Formula.The mapping relations for interrupting physical message and interrupt logic information are established after interrupt logic mapping table Sampling interrupt signal.
Be exemplified below: assuming that system generates 30 interruptions, these are interrupted respectively from 20 different functional modules.Each
Interruption follows an interruption physical message, which is established by interrupt logic mapping table and interrupt logic information
Mapping relations one by one.
Which further, physical message is interrupted to be used to indicate interrupt from functional module.In the expression of interrupt logic information
Whether disconnected priority level interrupts effective.
S202, interruption Packet Arbitration
Abort packet arbitration is the important content of interrupt arbitrage method, main to realize whether interruption effectively identifies, is interrupted
Grouping, the judgement of interrupt priority level.
It should be noted that common interrupt arbitrage method is to cache interrupt signal, then by caching will in
The selection and arbitration interrupted are completed after disconnected reading one by one.This method can be with avoidance breakout conflict, but largely shadow
The efficiency that reports interrupted has been rung, has especially been influenced more very when number of interruptions is numerous.
Further, interruption is grouped by the present embodiment, carries out interrupt priority level judgement using shift register, can
To reach interruption accuracy of judgement, and interrupt the short purpose that calls time.And the internal interrupt priority of each rank can adopt
It is reported with the mode (can turn clockwise, can also turn counterclockwise) for first entering first report or priority token rotation, it can be with
Avoid the problem that low priority interrupt can not report in time.
In other words, the present embodiment determines the interrupt levels of each interruption according to interrupt logic information.Each interrupt levels
Physical message is specified by user, i.e., configures in specified register.According to the interrupt levels of each interruption can by it is each interrupt into
Row grouping, that is to say, that have what interrupt levels, it can each interruption is divided into several groups.Using shift register to same group
Interior interrupt priority level is judged and is reported by the way of first entering first report or priority token rotation.
It should be noted that each grouping parallel of different interrupt levels judges the interrupt priority level of each self-grouping.
It is exemplified below: as shown in Fig. 2, Fig. 2 is a kind of interruption physical message provided in an embodiment of the present invention and interrupt logic
The mapping relations schematic diagram of information.Assuming that a total of 30 interruptions, a total of 3 grades of interrupt levels.One level interrupt has 3 interruptions,
Interrupt 3 interruptions that the port that physical message is 1~3 is one level interrupt；Second-level interrupt has 12 interruptions, interrupts physical message and is
4~15 port is 12 interruptions of second-level interrupt；Three-level interruption has 15 interruptions, interrupts the port that physical message is 16~30
15 interruptions interrupted for three-level.The physics number of every level-one interrupt source is specified by user (matches in specified register
It sets).30 interrupt according to user configuration, and interruption is grouped.Distribution principle, that is, user register Configuration Values.Such as user
It can configure the interruption that physical message is 1 to 3 grades of lowermost level interruptions.It is secondary that interruption after completing mapping enters interrupt priority level
The sanction stage.The present embodiment can be not fixed the inside number of interrupt levels, for example one level interrupt can configure 1, can also match
It sets more.Second-level interrupt can also configure one or more.Similarly, three-level interruption can also configure one or more.
It should be noted that expense can be increased too much by interrupting series, lose more than gain.It is most according to most of demand IP design
Pyatyi is supported to interrupt.
Further, in this embodiment disconnected rank is three-level interruption, therefore, each interrupt can be divided into 3 groups.Every group can benefit
It is distinguished with vernier.It can be configured according to according to vernier in every group, can determine the displacement of shift register；Every group can be with
By first enter first report or priority token rotation in the way of determine interrupt priority level.The direction of token rotation can be clockwise
Or it is counterclockwise.As can be seen that every group of interrupt priority level can use token rotation, it can not also rotate and be judged,
It is divided into two ways.It is possible to further determine the rotation mode of shift register according to token rotation mode.If using
First enter preferentially, it cannot be mutually nested between the interruption of same rank, it is necessary to execute and just can be carried out next same priority
Interruption report；The interruption of different stage (i.e. different grouping) can be mutually nested.
As shown in figure 3, Fig. 3 is a kind of abort packet schematic diagram provided in an embodiment of the present invention.Second-level interrupt passes through vernier
01 and vernier 02 distinguish, with interrupt priority level in second-level interrupt group be judged as example illustrate same group in interrupt priority level
Judgement.After grouping, each interruption in second-level interrupt group enters in a bit register (i.e. virtual marshalling, consideration by clock sampling
To the problem of combinational logic delay, virtual group accommodates up to 12 interruptions).Because there is the limitation of vernier, data displacement is only
It can occur in group.If using first enter priority it is high by the way of, then group in any one interrupt initiate request after, interrupt groups
Interrupt identification be set, and the interruption in other same group is forbidden to report again.If such as being schemed using token round robin
Shown in 4, Fig. 4 is a kind of schematic diagram of abort packet internal priority token rotation provided in an embodiment of the present invention.Assuming that
According to presetting, the interrupt priority level highest that physical message is 9 is interrupted, i.e., priority token 03 is 9.If it is up time pinwheel
Turn priority token, then priority arranges be followed successively by 9 > 10 > 11 > 12 > 13 > 14 > 15 > 4 > 5 > 6 > 7 > 8 from high to low；If it is inverse
Hour hands rotate priority token, then priority is followed successively by 9 > 8 > 7 > 6 > 5 > 4 > 15 > 14 > 13 > 12 > 11 > 10 from high to low.Setting is adopted
With clockwise rotation priority token mode, first timeticks can look for from left to right first effective interruption (example
For example interrupt the interruption that physical message is 6)；Shift register is integrally moved 5 positions by second timeticks to the left,
Move rear as shown in figure 5, Fig. 5 is the mode of another abort packet internal priority token rotation provided in an embodiment of the present invention
Schematic diagram.Second clock cycle, which is found, interrupts physical message as 9 the first later interruptions；So third clock cycle
(different rotary direction determines shift register shifting for interrupt priority level arbitration in completion virtual group group between interruption and virtual group
Position direction).Setting can look for from right to left first using rotation priority token mode counterclockwise, first timeticks
A effective interruption；Shift register is integrally moved to the right 6 positions by second timeticks.Second clock cycle seeks
It looks for and interrupts physical message as 9 pervious first interruptions；So the third clock cycle can be completed interrupt in virtual group group and
Interrupt priority level arbitration between virtual group.
Further, priority token 03 can be transmitted successively between interruption, as token-ring network.
S203, interruption report judgement
It is reported according to the interruption being respectively grouped obtained in S202, interruption to be reported is carried out with the Current interrupt being carrying out
Arbitration.Only high-priority interrupt can just interrupt the Current interrupt of execution.The present embodiment can use memory, such as
SRAM stores the interruption successively reported number.It is every to increase an interruption, and it is stored in a number；It is every to have executed one
Interrupt the number that just spues.So as to solve interruption to be reported with the priority arbitration for the Current interrupt being carrying out.
