Go back to Fig. 3, audio digital signal processor 326 couples above-mentioned at least two microphones 322,324.Audio digital signal processor 326 in radio reception processing unit 320 is controlled by main processing unit 310 by control unit 340, its order according to main processing unit 310 and receive and process radio reception data from outside.In detail, audio digital signal processor 326 is by control unit 340 and (for example control interface, I2C interface 370) and while receiving radio reception order, receive the audio signal of these microphones 322,324, and utilize the comparison conditions such as the amplitude, phase difference, radio reception time difference of these two or more audio signals, and utilize built-in audio operational method and following radio reception tupe to process these radio reception data, and send these radio reception data to codec 330 by the second audio frequency processing interface 360.
Codec 330 is processed interface 350 (high definition audio interface) by the first audio frequency and is couple to main processing unit 310, and is couple to radio reception processing unit 320 by the second audio frequency processing interface 360 (integral chip acoustic interface).That is to say, main processing unit 310 and performed application thereof can be processed interface (HDA interface) 350 by the first audio frequency and notify codec 330.In the time that audio digital signal processor 326 transmits radio reception data to codec 330 by the second audio frequency processing interface 360, codec 330 is just converted to by the radio reception data that meet the second audio frequency processing interface 350 the radio reception data that meet the first audio frequency processing interface 360 according to current audio frequency tupe, and by the first audio frequency processing interface 360, the radio reception data after conversion is offered to main processing unit 310 to carry out subsequent treatment.And main processing unit 310 carrys out processing audio by codec 330 and radio reception processing unit 320.In the present embodiment, codec 330 couples radio reception processing unit 320 except processing interface 360 by the second audio frequency, also can be by least one universal input output connecting pin (for example, universal input output connecting pin GPIO1, GPIO2) to couple radio reception processing unit 320, codec 330 can transmit radio reception tupe signal by these universal input output connecting pins GPIO1, GPIO2, and in follow-up description, illustrate radio reception tupe with and corresponding radio reception tupe signal.
The audio codec (codec) that audio treatment unit 300 can adopt the first audio frequency to process interface 350 and the second audio frequency processing interface 360 in this case embodiment is realized.In other words, codec 330 is to process the audio codec that the voice data at interface 360 is changed mutually by meeting the voice data at the first audio frequency processing interface 350 and meeting the second audio frequency.On the other hand, audio codec except as main processing unit 310 and radio reception processing unit 320 the data transaction bridge between transmission of audio data, its voice data that also can be used to main processing unit 310 to provide is decoded, and be converted to the audio signal that can play to speaker amplifier 140 or earphone 170, make apparatus for processing audio 300 be play music or recording file.
Illustrate that at this main processing unit 310 carrys out the actuating mode of processing audio by codec 330 and radio reception processing unit 320.Demand based on user in application, radio reception information is in audio digital signal processor 326 and codec 330, judge whether in advance ambient sound and the noise of filtering radio reception information according to application demand, giving main processing unit 310 by described radio reception information.Radio reception purposes is integrated into multiple radio reception tupe by this case embodiment, for example, and call mode, speech recognition pattern, recording mode.Call mode for carry out phone by this apparatus for processing audio 300 with other people or network communication used, therefore may need to eliminate ambient sound and avoid feedbacking the generation of sound.Speech recognition pattern needs strongly to eliminate ambient sound and noise, only retains the audio frequency of voice part, makes a mistake when the identification voice avoiding.Recording mode is ambient sound together radio reception need to be carried out to complete recording.
Because above-mentioned radio reception tupe need to allow audio digital signal processor 326 know, therefore in control unit 340, store the coded file that can offer audio digital signal processor 326, use in the time that radio reception processing unit 320 is started shooting, control unit 340 can download in audio digital signal processor 326 described coded file for use.In other words, when or being reset in initialization, the audio digital signal processor 326 of the radio reception processing unit 320 of this case embodiment will read coded file from control unit 340, to set respectively the demand of above-mentioned multiple radio reception tupes, and wait for that main processing unit 310 is by two universal input output connecting pin GPIO1, the 2 radio reception tupe signals that come that transmit of the first audio frequency processing interface 350 and codec 3330.Codec 330 by first audio frequency process interface 350 to obtain required radio reception tupe signal from main processing unit 310, and by universal input output connecting pin GPIO1, GPIO2 so that radio reception tupe signal is sent to radio reception processing unit 320.Audio digital signal processor 326 just can be selected one of them from these radio reception tupes according to radio reception tupe signal, processes foundation using the audio frequency as follow-up radio reception data.
For example, the radio reception tupe signal that universal input output connecting pin GPIO1, GPIO2 transmit and the correspondence of radio reception tupe can be as shown in following tables (1):
Table (1)
| ? | GPIO1 | GPIO2 | Radio reception tupe |
| Logic | 0 | 0 | Sleep pattern |
| Logic | 0 | 1 | Call mode |
| Logic | 1 | 0 | Speech recognition pattern |
| Logic | 1 | 1 | Recording mode |
Wherein, sleep pattern represents that audio digital signal processor 326 can not need to use at this moment, thereby is located at sleep pattern with power saving.By this, when control signal CS is maintained low level by main processing unit 310, and by two logics of general output connecting pin GPIO1, GPIO2 transmission " 0 " time, audio digital signal processor 326 is positioned at sleep pattern.When control signal CS is set in high levle by main processing unit 310, and general output connecting pin GPIO1, GPIO2 be respectively (logic " 0 "; Logic " 1 "), (logic " 1 "; Logic " 0 ") or (logic " 1 "; Logic " 1 "), the radio reception tupe of audio digital signal processor 326 is respectively just call, speech recognition or recording mode.
In the present embodiment, codec 330 also can be coupled to control unit 340, in the time that main processing unit 310 wants to allow audio digital signal processor 326 be positioned at sleep pattern, except allowing control signal CS maintain electronegative potential, also can notify control unit 340 by codec 330, to make audio digital signal processor 326 enter sleep pattern by controlling interface 370.In the time that main processing unit 310 is wanted to wake audio digital signal processor 326 up, except allowing control signal CS maintain electronegative potential, also can notify control unit 340 by codec 330, and it is waken up and start by the pin WR that wakes up of audio digital signal processor 326.
On the other hand, the clock signal CLK that audio digital signal processor 326 must characteristic frequency could carry out radio reception smoothly, for example, be 24MHz or the clock signal of 12MHz.If main processing unit 310 can provide the clock signal CLK that meets demand, can directly be provided by main processing unit 310.If but main processing unit 310 or other elements be not while providing the clock signal CLK of characteristic frequency, needs to arrange in addition clock pulse generator and supply clock signal CLK.
Fig. 6 is according to the schematic diagram of the apparatus for processing audio 600 described in second embodiment of the invention.The Main Differences of the first embodiment and the second embodiment is, the apparatus for processing audio 600 of Fig. 6 also comprises logical circuit 620 and clock pulse generator 610, and the clock signal CLK of audio digital signal processor 326 is provided by clock pulse generator 610.In detail, logical circuit 620 couples universal input output connecting pin GPIO1, GPIO2, its according to the selected multiple radio reception tupes of radio reception tupe signal one of them, use and provide clock pulse to produce signal ENCLK.Clock pulse generator 610 couples audio digital signal processor 326 and the logical circuit 620 of radio reception processing unit 320, and it receives clock pulse and produces signal ENCLK to determine whether provide clock signal CLK to radio reception processing unit 320.
The logical circuit 620 of the present embodiment by or door (OR) 630 realize, known based on above-mentioned table (1), if audio digital signal processor 326 is positioned at sleep pattern, namely universal input output connecting pin GPIO1, GPIO2 are all logic " 0 " time, it will be electronegative potential that clock pulse now produces signal ENCLK, make clock pulse generator 610 can stop providing clock signal CLK simultaneously, use power saving.
If audio digital signal processor 326 is positioned at other patterns turning round, namely universal input output connecting pin GPIO1, GPIO2 to have one at least be logic " 1 " time, it will be high potential that clock pulse now produces signal ENCLK, make clock pulse generator 610 can continue to provide clock signal CLK, allow audio digital signal processor 326 keep on the go.
Because the control unit 340 described in this case is to adopt in consumer electronic devices to process in start the embedded chip using, but this embedded chip is carried out needs a large amount of functions and each software and hardware device is carried out to initialization in the time carrying out the start of consumer electronic devices, causes the available machine time of consumer electronic devices to extend.Therefore, this case proposes following the 3rd embodiment to address the above problem.Fig. 7 is according to the schematic diagram of the apparatus for processing audio 700 described in third embodiment of the invention.Refer to Fig. 7, the Main Differences of the 3rd embodiment and the first embodiment is, for reducing the data volume of control unit 340 required processing, apparatus for processing audio 700 is the extra memory cell 728 that increases in radio reception processing unit 720, and this memory cell 728 stores audio digital signal processor 326 required coded file in the time of start.That is to say, in the first embodiment, described coded file is to be stored in control unit 340; In the 3rd embodiment, coded file is the memory cell 728 that is stored in radio reception processing unit 720.
By this, in the time of the audio digital signal processor 326 of initialization Fig. 7, control unit 340 is assigned instruction to audio digital signal processor 326 by controlling interface 370, so that audio digital signal processor 326 for example, obtains required coded file by data transmission interface 727 (, I2C interface) voluntarily from memory cell 728.This case embodiment utilizes the electronics formula of erasing can make carbon copies read-only memory (Electrically-Erasable Programmable Read-Only Memory; EEPROM) realize memory cell 728, but application the present embodiment person should know and can realize memory cell 728 with the relevant equipment that possesses memory function.
Therefore,, in the time that apparatus for processing audio 700 need to use function of radio receiver carrying out relevant application program, just audio instructions can be processed to interface (HDA interface) 350 notice codecs 330 by the first audio frequency.Now, main processing unit 310 also can utilize the first audio frequency to process the audio digital signal processor 326 that interface (HDA interface) 350 provides clock signal CLK to give radio reception processing unit 728.By this, codec 330 just can be processed the audio signal with loudspeaker 150～160 about earphone 170, and audio digital signal processor 326 can be processed the audio signal about microphone 322～324.
Audio digital signal processor 326 self also can possess electricity-saving function, that is to say, because adopting two GPIO pin GPIO1～GPIO2, this case embodiment switches above-mentioned multiple radio reception tupe (referring to table (1)), when therefore as long as audio digital signal processor 326 receives the signal of sleep pattern, just self is entered to sleep pattern; Comparatively speaking, in the time that audio digital signal processor 326 receives the signal except sleep pattern, just can be waken up and carry out corresponding function.
In the time that audio digital signal processor 326 is carried out to initialization, control unit 340 also can need only control data transmission interface 727 and download the important coded file of part to audio digital signal processor 326, and the object of these coded files is to allow audio digital signal processor 326 can wake memory cell 728 up.Then, audio digital signal processor 326 just can be downloaded remaining coded file from memory cell 728 voluntarily, and after coded file is downloaded, memory cell 728 is entered to sleep pattern, to reach the object of power saving.In addition,, if while not needing to use microphone 322,324 to carry out radio reception, audio digital signal processor 326 also can be advanced into sleep pattern certainly.In sum, apparatus for processing audio utilization described in the embodiment of the present invention can by first audio frequency process interface (as, high definition audio (HDA) interface) with second audio frequency process interface (as, integral chip acoustic (I2S) interface) the codec mutually changed of voice data (for example, audio codec (codec)), use as this case and there is the main processing unit at the first audio frequency processing interface and adopt the second audio frequency to process the bridge of data transaction between interface, thereby integrate above-mentioned both, realize this audio frequency processing.By this, apparatus for processing audio is not limited to by just can at high definition audio (HDA) interface of original central processing unit, can adopt the audio digital processing device of any kind to realize different audio frequency processing operation methods, and needn't only limit to original beam forming (beamforming) operation method.
In addition, because beam forming operation method must arrange in sound source front radio equipment (microphone), if but adopt other preferably audio operational rule not necessarily to microphone be set in locality.Therefore, this case can allow the setting of microphone more flexible, adopt the apparatus for processing audio of contact panel operation also can avoid glass yield and the price problem because producing at panel front holes, and noise suppressed can make apparatus for processing audio region around all can carry out radio reception time.
Finally it should be noted that: above each embodiment, only in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or some or all of technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
