Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.

Please refer to Fig. 2, be depicted as the schematic diagram of the detection system of the data handling system that the embodiment of the invention provides.The detection system 200 of described data handling system comprises: judge module 220, timer 240 and state reflection module 260.

Described judge module 220 is used for the state of detection messages input FIFO4 and message output FIFO6, and according to the state of described message input FIFO4 and message output FIFO6, sends control command to described timer 240.Wherein, when described message input FIFO4 reaches capacity state and described message output FIFO6 for empty the time, described judge module 220 sends starting command to described timer 240, so that timer 240 picks up counting; When described message input FIFO4 does not reach capacity state or described message output FIFO6 for empty the time, described judge module 220 sends to described timer 240 and ceases and desist order, so that described timer 240 stops timing and zero clearing.

Be provided with a threshold value in the described timer 240, when timer 240 starts and timing when having reached described threshold value, described timer 240 sends one to state reflection module 260 and confirms order.Described state reflection module 260 receives after timer 240 sends the order of accepting one's fate really, confirms that then the data handling system of chip to be measured makes a mistake, and carries out mistake and report.Described threshold value can be according to the frequency of the transfer of data of the upstream and downstream chip of chip to be measured, and the data processing efficiency of the inter-process module 2 of chip to be measured is provided with, with the delay of removing the transfer of data that normal data handling procedure the brought influence for testing result.

Understandablely be, after timer 240 had started and picked up counting, judge module 220 can no longer send starting command, or timer 240 ignores and fall the starting command that judge module 220 sends subsequently, and kept time status always.And if only if timer 240 receives cease and desist order after, timer 240 just stops timing and zero clearing.

As from the foregoing, whether the embodiment of the invention is to come the inter-process module of judgment data treatment system to make a mistake by the state of judging message input FIFO4 and message output FIFO6.Concrete, in the system of whole data processing, cause the reason that data path interrupts to have three kinds: first kind is that the link of upstream and downstream chip breaks down; Second kind is that downstream chip can't receive data and produce back-pressure; The third is the internal fault of data handling system to be tested.Because first kind be not that fault causes, so the embodiment of the invention forecloses it, and second kind belong to a kind of normal protection mechanism, therefore also will get rid of when carrying out fault detect.To sum up, judge at first whether message input FIFO4 reaches capacity,, can judge that the inter-process module of the data handling system of generation test can receive and issue data as long as message input FIFO4 does not reach capacity.If message input FIFO4 reaches capacity, to judge then whether message output FIFO6 is empty, if message output FIFO6 is not sky then can thinks that message output FIFO6 can receive data from the inter-process module, the inter-process module is normal, and why message input FIFO4 reaches capacity then is because downstream chip has produced back-pressure.If message input FIFO4 has reached saturated, and message output FIFO6 be empty, and the duration of this process surpassed default time threshold, illustrate that then message output FIFO6 can't be from inter-process module reception data, fault has taken place in the inter-process module.

Understandable is that the detection system of the data handling system that the embodiment of the invention provided and the functional module of chip to be measured can be integrated in on the chip piece, also can be divided in different chips or the device.

The detection system of the data handling system that the embodiment of the invention provided is come the state of the inter-process module of judgment data treatment system by the state of detection messages input FIFO4 and message output FIFO6, simple to operate, and can finish voluntarily by system, need not human intervention, be convenient in time find the fault of inter-process module, improved the stability of system.
