Fig. 4 is the flow chart of the digital signal processing unit in Fig. 3 provided in an embodiment of the present invention, as shown in figure 4, bag
Include：
Step S401, software error detects.
After system electrification initialization, software error detection is carried out on digital signal processing unit.
Detection content can be that internal storage code section is rewritten, and/or stack overflow, and/or constant table rewriting etc., judge whether
There is the operation that bus writes these addresses.If detecting the operation for writing these addresses, illustrate that software code has malfunctioned.
Preferably, the software error of active detecting includes：Internal storage code section is rewritten, and/or stack overflow, and/or constant
Table rewriting etc..
Step S402, software error is detected, processor enters not maskable interrupts, and it is normal to stop transmission processor state
Notification message.
The processor of digital signal processing unit enters not maskable interrupts, normal so as to actively stopped processor state
The transmission of notification message.
Preferably, the specific form of the normal notification message of processor state does not limit, and is defined by both sides' agreement.
Step S403, software error is not detected by, timing sends the normal notification message of processor state.
The normal notification message of processor state regularly can be sent to central processing unit, read-me does not enter into some yet
Abnormal endless loop etc., the normal notification message of processor state is set and sends to CPU so as to lead to not establishment.
Fig. 5 is the flow chart of the CPU in Fig. 3 provided in an embodiment of the present invention, as shown in figure 5, including：
Step S501, timing monitoring status of processor normally notifies exception.
If receiving the normal notification message of processor state, parse and verify correctly, then confirm sending processor state just
The digital signal processing unit of normal notification message does not find software error also.If receive the normal notification message of processor state but
Check errors, or timing normally notify to disappear to the processor state for not receiving the transmission of some digital signal processing unit yet
Breath, then confirm that software error occurs in the digital signal processing unit.
Preferably, processor state normally notifies that abnormal is probably that digital signal processing unit detects software error actively
Stop the normal notification message of processor state to send, it is also possible to which digital signal processing unit oneself does not detect software mistake
By mistake, but processor state normally notifies exception etc..
Preferably, the software error that digital signal processing unit oneself does not detect includes：Error code causes program to be entered
Enter endless loop, code runs winged etc..
Preferably, it can for the first time receive for a period of time to start after processor state normally notifies after power-up initializing and determine
When monitor.
Step S502, timing monitor and detection normally notifies exception to processor state, then controls no longer to the processor shape
State normally notifies abnormal digital signal processing unit to assign business, and normally notifies normal unit to refer to processor state
Send, run on the signal processing unit that the business for making newly to initiate is still able to normally notify in normal processor state, Bu Huiyin
It is abnormal to play new use.
Step S503, the internal memory of exception processing unit is saved in server, judges that timer time is arrived or internal memory is protected
Deposit and finish.
Live internal memory when exception will occur recorded in server in time, so that the existing technical Analysis of later use is wrong
Reason by mistake.But in order to ensure the disposal ability of whole system, can not be at indefinite extension exception data signal after noting abnormalities
The resetting time of unit is managed, it is necessary to design a rational timer value to control preservation data time.
Preferably, address and the length of export internal storage data are preset, can be internal memory in part or all of piece, and/
Or register, and/or the outer external memory of piece.
Preferably, the log file that preserves when corresponding to software error each time in server, can all have numbering, the date,
The information such as time can be distinguished.
Preferably, the maximum time that timer limitation data save operation allows.
Step S504, software reset notifies abnormal digital signal processing unit.
Positive return, restarting and the abnormal digital signal processing unit of loading, can temporarily solve application code mistake
Exception caused by rewriting internal memory, also can solve the problem that some bit or more of internal memory caused by high-energy ray or other environmental factors
The situation that individual bit is written over, because not being the rewriting operation that processor is carried out, it is difficult to such issues that find and position.
Step S505, processor state normally notifies normal digital signal processing unit, can assign new business.
Processor state normally notifies normal digital signal processing unit, can assign new business.Appointment condition also may be used
To be limited according to some other conditions, such as expense of the disposal ability of processor and new business etc..
The scheme provided according to embodiments of the present invention, while software error is surveyed in processor selftest, by system
Other processors carry out cooperation detection software error, improve software error detection probability.It is meanwhile relative by software in system
Stable processor detects to the processor of the relatively easy error of software, improves the stability of detection.System detectio arrives
After software error occurs for some processor, in-situ software error internal storage data preservation is carried out immediately, is easy to subsequent analysis mistake former
Cause, while automatically reseting can make processor recover normal in time, simultaneity factor can specify the business newly initiated in normal operation
Processor on perform.
Although the present invention is described in detail above, the invention is not restricted to this, those skilled in the art of the present technique
Various modifications can be carried out according to the principle of the present invention.Therefore, all modifications made according to the principle of the invention, all should be understood to
