In one embodiment, as shown in Fig. 2, providing a kind of localization method of endless loop, it is applied to Fig. 1 in this way In computer equipment for be illustrated, comprising the following steps:

Step 202, when detecting that endless loop occurs in external interrupt service routine, triggering quick-speed interruption service routine is interrupted External interrupt service routine.

External interrupt service routine abbreviation IRQ (Interrupt Request) is interrupted, and is referred to general in central processing unit Interrupt requests, the interrupt processing for modules in computer equipment.IRQ interruption can support a variety of IRQ to interrupt simultaneously Source, and the running priority grade that IRQ is interrupted is higher than non-interrupted program, bring into operation corresponding service routine in triggering.

Quick-speed interruption service routine abbreviation FIQ (Fast Interrupt Request) is interrupted, and is referred in central processing unit Fast interrupt requests, in computer equipment quickly, the interrupt processing of low latency.FIQ interruption can support one kind or compared with Few several interrupt sources, running priority grade are interrupted higher than IRQ, and bring into operation corresponding service routine in triggering.

Endless loop, which refers to, controls the program that can not be terminated by itself.There is endless loop and refers to calculating in external interrupt service routine The system of machine equipment, which is fallen into IRQ interrupt service routine, cannot terminate and exit, so as to cause system program and all applications Program is no longer executed to expected follow-up process, and part IRQ is interrupted or all IRQ interruption will be responded no longer.

Computer equipment can detect the execution of program each in system.When computer equipment detects in outside When endless loop occurs in disconnected service routine, computer equipment can trigger quick-speed interruption service routine.Since quick-speed interruption services journey The priority of sequence is higher than the priority of external interrupt service routine, when computer equipment triggers quick-speed interruption service routine, Computer equipment can execute quick-speed interruption service routine with immediate precedence, so that external interrupt service routine is interrupted.

Step 204, it obtains in generated when passing through triggering quick-speed interruption service routine interruption external interrupt service routine Disconnected result.

When triggering quick-speed interruption service routine to interrupt external interrupt service routine, the available generation of computer equipment Interruption result.Wherein, interrupting can wrap in result containing with being interrupted the interruption title of program, the breakpoint for being interrupted program Location, the operational mode for being interrupted program, be interrupted code at the breakpoint of program, IRQ interrupt number and other as a result, not doing herein It limits.

Step 206, the triggering times that triggering quick-speed interruption service routine interrupts external interrupt service routine are obtained.

There can be a counter in computer equipment, interrupt external interrupt for recording triggering quick-speed interruption service routine The triggering times of service routine.When first time triggering quick-speed interruption service routine interrupts external interrupt service routine, counter Triggering times can be calculated as 1, when the quick-speed interruption service routine that sets out again interrupts external interrupt service routine, counter can Triggering times are calculated as 2.

Quick-speed interruption service routine is triggered in the counter that computer equipment can be got in real time interrupts external interrupt clothes The triggering times for program of being engaged in.

Step 208, when triggering times are less than default triggering times, triggering quick-speed interruption service routine interrupts external interrupt Service routine obtains the interruption generated every time as a result, and generating interrupting information according to the interruption result of acquisition.

Default triggering times can be what user pre-set, can also be what computer equipment generated.Wherein, it presets Triggering times can be related to interrupt source, and when interrupt source is the interrupt source of specified non-timed device, default triggering times can be with Be set as 10 times, it is 20 inferior；When interrupt source is timer interruption source, timer can be touched according to the down trigger period of setting It sends out quick-speed interruption service routine and interrupts external interrupt service routine, for example, the down trigger period being arranged in timer is 10s/ Secondary, timer can trigger a quick-speed interruption service routine every 10s and interrupt external interrupt service routine.

After getting triggering times, triggering times and the default triggering times that can be will acquire are compared computer equipment Compared with, and obtain comparison result.When the comparison result that computer equipment obtains is that triggering times are less than default triggering times, calculate Machine equipment can trigger quick-speed interruption service routine again and interrupt external interrupt service routine, and obtain triggering quick-speed interruption again Service routine, which interrupts, to interrupt caused by external interrupt service routine as a result, until the triggering times of computer equipment acquisition are not small In default triggering times.

When triggering times are greater than default triggering times, the available interruption generated every time of computer equipment is as a result, simultaneously Interrupting information is generated according to the interruption result of acquisition.It is produced that is, can wrap in the interrupting information that computer equipment generates containing each Raw interruption result.

Step 210, dis-assembling code is generated according to interrupting information.

Dis-assembling, which refers to the process of, switchs to assembly code object code, that is, machine language is converted to compilation language Speech.Wherein, machine language refers to that the computer equipment indicated with binary code can be with a kind of machine of Direct Recognition and execution Instruction；Assembler language is also known as symbolic language, specific assembler language and specific machine language instruction collection be it is one-to-one, Assembler language is easy for the language that user distinguishes, remembers and writes.

The interrupting information that computer equipment is got can be and be indicated with machine language.Computer equipment is in getting After disconnected information, corresponding dis-assembling code can be generated according to the interrupting information of acquisition.Wherein, during computer equipment is got When disconnected information can be triggering quick-speed interruption service routine interruption external interrupt service routine every time, generated interruption result Set.

Step 212, breakpoint address corresponding with interrupting information is obtained, according to outside breakpoint address and dis-assembling Code location The endless loop position of portion's interrupt service routine.

The available breakpoint address corresponding with interrupting information of computer equipment, wherein breakpoint address is external interrupt clothes The breakpoint address for program of being engaged in.The corresponding breakpoint address of the available interrupting information of computer equipment, computer equipment can bases Breakpoint address finds code corresponding with breakpoint address in dis-assembling code, and computer equipment can be corresponding from breakpoint address Code in navigate to the endless loop position of external interrupt service routine.

In the present embodiment, when computer equipment detects that endless loop occurs in external interrupt service routine, triggering is quick Interrupt service routine interrupts external interrupt service routine, obtains and interrupts external interrupt service by triggering quick-speed interruption service routine It is generated when program to interrupt as a result, obtaining the triggering time that triggering quick-speed interruption service routine interrupts external interrupt service routine Number triggers quick-speed interruption service routine again and interrupts external interrupt service routine when triggering times are less than default triggering times, And interruption is generated as a result, generating interrupting information according to all interruption results, and generate dis-assembling code according to interrupting information, it obtains Breakpoint address corresponding with interrupting information is followed according to breakpoint address and the dead of dis-assembling Code location external interrupt service routine Ring position.It is quick by triggering since the priority of quick-speed interruption service routine is higher than the priority of external interrupt service routine Interrupt service routine interrupts the external interrupt service routine for endless loop occur, and according to the breakpoint in interrupting information The dis-assembling code of location and generation positions endless loop, without being inserted into Debugging message output statement or being debugged by hardware Tool positions, and can be improved the location efficiency of endless loop.Wherein, the endless loop of external interrupt service routine can be system journey The endless loop of sequence can also be the endless loop etc. of nutritional program, interrupt external interrupt by triggering quick-speed interruption service routine Service routine can make endless loop positioning apply more extensive, and the validity and flexibly of a variety of endless loops positioning can be improved Property.

In one embodiment, a kind of localization method of the endless loop provided can also include the mistake for determining target interrupt source Journey specifically includes: traversal interrupt source；The target interrupt source of preset condition is determined for compliance with from interrupt source；When detecting in outside When endless loop occurs in disconnected service routine, quick-speed interruption service routine is triggered by target interrupt source and interrupts external interrupt service journey Sequence.

Interrupt source can be used to indicate that the source that can issue interrupt request singal.In one embodiment, any to be used for The interrupt source of triggering external interrupt service routine can be set to the interrupt source for triggering quick-speed interruption service routine.Mesh Mark interrupt source can be used for triggering quick-speed interruption service routine, so that external interrupt service routine is interrupted.Interrupt source can be Universal input and output port GPIO (General Purpose Input/Output), the port for being inserted into magnetic card, connection computer The keyboard etc. of equipment.Preset condition can be user setting, can also be computer equipment according to the use of each interrupt source Situation setting.The interrupt source for meeting preset condition can be in idle interrupt source, the interrupt source for not falling into endless loop, refer to Fixed interrupt source etc..

The available preset condition set of computer equipment.Computer equipment can be to the progress time of all interrupt source It goes through, and is determined for compliance with the target interrupt source of preset condition in all interrupt source according to preset condition.Wherein, target interrupt source It can be and carry out manually-operated interrupt source convenient for user.Preset condition can be user and be pre-set by computer equipment , it can also be what computer equipment was configured according to the use state of interrupt source.For example, computer equipment get it is pre- If condition is in idle interrupt source, computer equipment can be searched in all interrupt source in idle interrupt source, At this point it is possible to modify to the hardware circuit in computer equipment, computer equipment can will be found in idle Interrupt source is as target interrupt source.

When computer equipment does not find the target interrupt source for meeting preset condition, computer equipment can choose one As target interrupt source, timer can be interrupted a timer being in idle condition with clocked flip quick-speed interruption service routine External interrupt service routine.

When computer equipment detects that endless loop occurs in external interrupt service routine, computer equipment can pass through target Interrupt source interrupts external interrupt service routine by quick-speed interruption service routine to trigger quick-speed interruption service routine.For example, The target interrupt source that computer equipment determines is universal input and output port GPIO, when computer equipment detects that external interrupt takes When endless loop occurs in business program, computer equipment can trigger quick-speed interruption service journey by universal input and output port GPIO Sequence, so that quick-speed interruption service routine be made to interrupt external interrupt service routine.

In the present embodiment, computer equipment is determined for compliance with the mesh of preset condition by traversal interrupt source from interrupt source Interrupt source is marked, when detecting that endless loop occurs in external interrupt service routine, quick-speed interruption service is triggered by target interrupt source Program interrupt external interrupt service routine.Computer equipment finds the target interruption for meeting preset condition by preset condition Source can quickly find target interrupt source, to improve the effect that quick-speed interruption service routine interrupts external interrupt service routine Rate.
