Embodiment

Hereinafter with reference to correlative type, detection system and method according to preferred embodiment of the present invention are described.

As shown in Figure 2, comprise an end host 21 and a circuit board 3 according to the detection system 2 of preferred embodiment of the present invention, wherein circuit board 3 comprises a System on Chip/SoC 31, a storer 32 and a processor 33.

End host 21 produces a trigger pip TRI, the trigger pip TRI of System on Chip/SoC 31 receiving terminal main frames 21 also produces an interrupt INT, storer 32 stores the pairing trace routine code 321 of interrupt INT, processor 33 receives interrupt INT and according to the pairing trace routine codes 321 of interrupt INT in the interrupt INT execute store 32, to produce a testing result RUT, System on Chip/SoC 31 is sent to end host 21 with testing result RUT by processor 33.

Interrupt INT is the interruption (SMI, System Management Interrupt) of a system management.Circuit board 3 is motherboards.End host 21 is mobile communications devices, and storer 32 can be the ROM (read-only memory) (BIOS ROM) of ROM-BIOS.

As shown in Figure 3, in the present embodiment, circuit board 3 more comprises an output and goes into communication port 34, a System on Chip/SoC 35 and a random access memory 36, and detection system 2 more comprises a distance host 22 and a distance host 23.

Output is gone into the trigger pip TRI of communication port 34 receiving terminal main frames 21 and is transmitted trigger pip TRI to System on Chip/

SoC

31,31 pairs of processors of System on Chip/SoC 33 produce after the interrupt INT, processor 33 is that the program code 321 that sees through in System on Chip/SoC 35 and System on Chip/SoC 31 pseudostatic rams 32 is program code 361 to random access memory 36, and processor 33 executive routine codes 361 are to produce testing result RUT then.Testing result RUT sees through System on Chip/SoC 35 from processor 33 to be sent to System on Chip/SoC 31, and it is to receive testing result RUT and transmit testing result RUT to end host 21 from System on Chip/SoC 31 that communication port 34 is gone in output.It is a serial communication port (Serial Communication Port) that communication port 34 is gone in output.

In the present embodiment, circuit board 3 can be in power down state earlier, the back is waken up by the trigger pip of end host 21, processor 33 is finished after the wake up procedure and processor 33 as yet before the not load operation system, the interrupt INT that System on Chip/SoC 31 produces is the interruption SMI of highest ranking, so processor 33 meeting priority processing are interrupted SMI and can not interrupted by other interruption or operation, so the trace routine of interrupt INT correspondence must be carried out by processor 33.

In addition, distance host 22 or distance host 23 produce one and detect requirement, end host 21 receives to detect and requires also to require to produce trigger pip TRI according to detecting, and after testing result RUT generation, distance host 22 sees through end host with distance host 23 and obtains testing result.Can be connected by network (LAN or world-wide web) between end host 21, distance host 22 and the distance host 23, therefore, the developer not only can be at end host testing circuit plate, also can be in the distance host testing circuit plate of different location.That is to say that developer and circuit board need not in same place, and many people detect same circuit board throughout jointly simultaneously.

As shown in Figure 4, the detection method according to preferred embodiment of the present invention comprises step S01 to step S05.

Step S01 produces a trigger pip by an end host.

Step S02 is the trigger pip by a circuit board receiving terminal main frame to be tested.

Step S03 produces an interruption according to trigger pip.

Step S04 is according to interrupting a pairing trace routine code to produce a testing result.

Step S05 transmits testing result to end host by circuit board to be tested.

The detection method of present embodiment can be applicable to aforesaid detection system, and aforesaid detection system discussed in the embodiment of Fig. 2 and Fig. 3, so repeat no more the detection method of present embodiment.

In sum, because of having System on Chip/SoC, storer and processor according to remote detecting system of the present invention and method, so the trigger pip that System on Chip/SoC can the receiving terminal main frame and processor produced is interrupted, processor can interrupt pairing trace routine code to produce testing result in the execute store before the load operation system, therefore the developer be able to according to testing result promptly the correction circuit plate or with the mistake of circuit board relevant apparatus, to improve the development efficiency of circuit board.

The above only is an illustrative, but not is restrictive.Anyly do not break away from spirit of the present invention and category, and, all should be contained in the appended claim its equivalent modifications of carrying out or change.
