Description
Technical field
The invention belongs to the software test field, relate in particular to a kind of detecting and analysing system and method based on embedded software.
Background technology
Along with the progress and the element quality of computer hardware technology progressively improves, the integrated amount of element also increases greatly, thereby the hardware performance of embedded device is greatly improved; Meanwhile,, total system is operated on high performance, the reliable software platform, for the application that realizes various large-scale complexity is laid a good foundation by adopting ripe commercial embedded OS.In the face of the increase of system complexity, need embedded application software powerful, stable performance to adapt with it naturally.So the size of code of software is also increasing in the embedded system exploitation, the speed increment of the size of code of electronic product every two years just to turn over.Simultaneously, system requires again to use and will simplify efficiently, reliable and stable, and this makes that the exploitation of software shared importance in the total system exploitation is more and more higher, and the development time is also more and more longer, and the quality of software has played conclusive effect to the final mass of product.Therefore, pressing for a kind of instrument can carry out the test and the analysis of real-time online to the software of embedded system in each stages such as the veneer stage of software development, integrated stage, system's stages, to guarantee the performance and the reliability of system.
Popular on the market testing tool roughly is divided into the testing tool of pure software and the testing tool of pure hardware.Wherein, what the testing tool of pure software adopted is that software is got technology ready, promptly in tested code, insert some functions, main inlet, exit at function, and ground such as branch, insert specific function, so that the time that computing function is carried out, utilize these functions to realize the generation of test data, test data is delivered in the shared drive of Target Board system simultaneously.And in goal systems preprocessing tasks of operation, finish the pre-service of these test datas, the data after will handling then send back on the main frame on network interface by target machine or the serial ports, carry out follow-up analysis.By this process, the tester is known the running status that program is current.
From then on analyze as can be known, the testing tool of pure software needs to finish by means of user's target processor, promptly needs to take the resource on the Target Board.Simultaneously, the test philosophy of the testing tool of pure software has two characteristics that certainly exist---pitching pile function and preprocessing tasks.Analyze: because the existence of having inserted pitching pile function and preprocessing tasks increases the code of system, more seriously these codes can have very big influence (surpassing 50%) to the operational efficiency of system.Simultaneously, function itself will have its implementation procedure, and it will be finished the generation of data and keep in, and these functions also may be interrupted by the higher interrupt routine of other priority in its implementation procedure.Preprocessing tasks need take goal systems CPU processing time, shared drive and communication port finish the processing of data, data on give.Because the existence of these drawbacks, when adopting the pure software testing tool that goal systems is tested, the ownership goal system moves under a kind of false environment, and the data that we caught also are accurate inadequately.Adopt the testing tool of pure software that following deficiency is arranged:
Defective 1: lack performance evaluation, it can not be analyzed accurately to the time index of function in the ownership goal system and task run.
Defective 2: when doing coverage rate analysis,, and get the operation that too much will influence system ready because will get ready in a large number, can not be too big so can only do the procedure quantity of unit coverage rate analysis and unit.
Defective 3: the ability that Memory Allocation is analyzed and checked not.
Pure hardware testing instrument is example with the logic analyser, and logic analyser is by the dual-port flag register, and when code was carried out, the dual-port flag register put 1 to the code of carrying out simultaneously, by whether code is put 1, comes the situation of the current operation of determining program.Analyze: when system opens buffer memory (CACHE), get an instruction and then this code is put 1.And this instruction might not be carried out.Adopt the testing tool of pure hardware that following deficiency is arranged:
Defective 1: can adopt the instruction prefetch technology when CACHE opens us, from external memory, read one section code in one-level CACHE, at this moment logic analyser will report that these codes have been performed, but the code that in fact is sent among the CACHE may not be hit at all.Must close CACHE for fear of this error, and CACHE to turn off be not the real running environment of system just, sometimes even can cause system normally to move owing to CACHE closes.
Defective 2: the ability that Memory Allocation is analyzed and checked not.
To sum up, when prior art is carried out embedded software test by software or hardware testing instrument, exist: the code expansivity is too high, be interrupted easily, and the hardware plate resource of occupying is more, measuring accuracy and accuracy rate are not high, and the test analysis object is the problem of variation or the like inadequately.
