Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and detailed description of the invention the present invention is further described.
As shown in Figure 1 to Figure 3, a kind of apparatus debugging method, comprise the following steps:
1. analogue audio input
In VC program, remove to read under a certain path the audio file of a WAV form according to the interval of the 48K sample rate of equipment, export finally by PC speaker. The audio signal of emulator the overall process of last audio signal output can be input to by the method. VC gives tacit consent to 0 passage input, 0 passage output. Input/output port can be changed by changing simInPort and simOutPort. So can emulate the effect of internal processor algorithm more really, in debugging process, eliminate CCS compiling, packing, restart, all multi-steps such as operation.
2. outloop and inloop
In current double-core processes, containing anologIf, uppIf, multiple audioIf interface such as netAudioIf, if whole system cannot normal operation, how quickly location is host CPU or from the problem of CPU, or analogue audio frequency drives, DAB drives, the problem of UPP, is always up means of comparatively difficulty. In this programme, it is proposed to the concept of outloop and inloop, this problem is made to become masterly. Fig. 2 is the flow graph of system audio signal and outloop and inloop mark position, system default outloop and inloop is false. Meanwhile, audio data frame is also had to add up at each audioIf interface, by each interface, it is possible to more quickly problem analysis place.
3. pair detection of any channel levels and recording
Formulating after a new Topo structure, tending not to disposable just have voice output. According to topo structure, a certain passage of each APU is carried out level monitoring, can quickly position the topo problem place formulated. Same, in debugging algorithm process, what kind of change is audio signal, after algorithm, occur most important. Traditional method of testing is analyzed mainly by the output signal of analog output mouth, is all analogue signal due to what gather, it does not have digitized, and, also other algorithm after topo after algorithm output, analyze inconvenience. Voice data is processed and with the addition of the debugging methods such as the recording to this passage and detection by each passage of each processor of this programme, by a total enable, it is possible to improve the utilization rate of CPU, concrete flow chart such as Fig. 3.
