In the example of Fig. 1, device 102 comprises one or more input units 116, and described input unit 116 produces may need the Wave data handled.In some embodiments, treat to comprise initial data by the data that device 104 is handled.For instance, for any purpose except that being transferred to device 104, device 102 data that can not handle from input unit 116.Therefore, device 102 not deal with data to improve by the represented any feature of data.As a particular instance, device 102 not deal with data for example to improve attribute by frequency response, signal to noise ratio or the accuracy of the represented multimedia waveform of data, biological waveform or surrounding environment waveform.
In certain aspects, device 102 comprises preprocessor 118, but described preprocessor 118 preprocessed datas (for example, original analog data) are to be used to be transferred to device 104.For instance, preprocessor 118 can be carried out waveform processing to data.This waveform processing can comprise (for example) pulse code modulated coding or sigma-delta modulating-coding.Therefore, opposite with the Wave data of further handling (for example, compressed, as transmitting) in conventional system, device 102 can be transferred to Wave data device 104.
In certain aspects, improvement by data (for example, the raw analog waveform data) at least one represented feature can comprise extraction (for example, by extractor assembly 124) by at least one represented feature of device 102 data that produced (for example, original analog data).For instance, extraction can relate to from the data that received (representing original sense data) extraction voice signal, extracts biological parameter (for example, heartbeat waveform), extract surrounding environment parameter (for example, pressure waveform) or a certain other similar operations.Advantageously, can improve by the mode of the represented feature of data and carry out this process.For instance, extraction can relate to filtering, denoising, noise removing or a certain other proper technology.
In certain aspects, extraction can relate to the indication of extraction about the data (representing original sense data) that received.For instance, extraction can comprise the indication of extracting biological parameter (for example, heart rate value), indication or a certain other similar indication of extracting surrounding environment parameter (for example, force value).In addition, can improve by the mode of the represented feature of data and carry out this process.For instance, the indication of heart rate (for example, as deriving from a plurality of transducers that detect heartbeat waveform) can be through equalization to provide improved final heart rate value.Can carry out similar operations to be used for other indication of biology or surrounding environment parameter.Improve feature and also can comprise machine readable or the human-readable of improvement by the represented value of analogue data.For instance, the indication of extracting or calculating heart rate (or a certain other parameter) can improve the machine readable of analogue data or the feature of human-readable.Herein, can by future the autobiography sensor pulses switch be the indication that numerical heart rate value (or value of a certain other type) obtains (for example, extract or calculate) heart rate (or a certain other parameter).
With extracting (or after extracting), waveform processor 136 can be carried out the waveform processing of wanting to the Wave data that is extracted.For instance, as hereinafter with more detailed argumentation, this waveform processing can relate to by execution is for example balanced, echo is eliminated, the operation of initiatively noise removing, the calculating of filter tap, sidetone processing, biological relevant (for example, medical treatment is correlated with) processing, voice command and identification and ambient environmental conditions processing improves at least one feature of data.

In certain aspects, but processor 110 deal with data and further reduce device 102 desired processing promoting the transmission of auto levelizer 102 under some situations.For instance, wave coder 126 can provide the treated data that are through the waveform coding form (for example, through pulse code modulation data or through the sigma-delta modulating data).These data can be transferred to device 102 subsequently and need not any further processing (for example, compression) except that the standard transmission relevant treatment.Therefore, opposite with the treated data of expression waveform, device 104 also can be transferred to Wave data device 102.As hereinafter discussing, under this kind situation,, therefore can carry out less processing at device 102 places because device 102 is the data of the form that can be easy to be provided to output device with reception.
After deal with data, device 104 sends to suitable destination with data.For instance, the LAN of device 104 or wide area network traffic assembly 128 can send to another device (for example, to the Wide Area Network of for example cellular network or to the internet, not shown among Fig. 1) via suitable communication link with treated data.
Discuss as mentioned, device 104 can send it back treated data device 102.For instance, device 102 for the end user's of data situation under or device 102 be more suitable in treated data forwarding under the situation of final destination, install 104 and treated data can be sent it back device 102.Herein, the transmission plan that optionally uses on the apparent link 106 of processor 110 and come coded data surely and subsequently encoded data are provided to transmitter 130.
The receiver 132 of device 102 can be provided to the data that received processor 108 to be used to the relevant treatment of communicating by letter subsequently.For instance, the transmission plan that optionally uses on the apparent link 106 of processor 108 and the fixed data of decoding and being received.
Can how to implement the unloading processing in order to further specify, to comprise the wireless device of mobile phone for example or entertainment device (for example, audio player) and install the example that 102 situations that comprise the embodiment of the telephone headset that is used for wireless device are discussed the unloading processing tout court at device 104.Under this behaviour in service, various types of processing can be unloaded to device 104 from telephone headset 102.For instance, in some embodiments, can be desired for telephone headset 102 provides echo elimination or active noise removing.Herein, input unit 116 can comprise the microphone of sensing surrounding environment sound.Thereby telephone headset 102 as mentioned argumentation original sensing surrounding environment voice data (for example, waveform) is transferred to device 104.
By understanding above summary, will discuss the additional detail of incorporating the system that unloading processing and operations associated are arranged in more detail in conjunction with Fig. 2 A, Fig. 3 and Fig. 4.The exemplary components of Fig. 2 A illustrative system 200, described system 200 comprises wireless peripheral unit 202 and wireless device 204, it can be similar to wireless device 102 and wireless device 104 respectively in aspect one or more.Fig. 3 is about being transferred to data the operation of another device through execution from the device that produces sense data with (for example).Fig. 4 is about being transferred to data the operation of another device of dateout through execution from a device with (for example).For simplicity, the operation of Fig. 3 and Fig. 4 (or any other operation of argumentation herein or teaching) can be described to be carried out by specific components (for example, system 200).Yet, should be appreciated that described operation can be carried out and can be used the assembly of different numbers to carry out by the assembly of other type.Should also be clear that one or more in the operation that in given embodiment, can not use herein to be discussed.
Fig. 2 A tracing device 202 is the example of the peripheral unit of wireless device 204.For instance, wireless device 204 can comprise the air station of communicating by letter with one or more other devices (for example, WAP (wireless access point)).In some embodiments, wireless device 204 can comprise mobile phone.Under this kind situation, peripheral unit 202 can be including (for example) for example ancillary equipment of telephone headset, watch, medical treatment device or a certain other appropriate device.Should be appreciated that can be except that the enforcement of the variety of way the specific description herein teaching herein.Therefore, in other embodiments, device 202 can not be a peripheral unit.
Fig. 2 A is the example that communicates via the air interface that is used for human body local area network network or personal area network of tracing device 202 and 204 also.Yet, should be appreciated that device 202 and 204 can use the communication link of other type to communicate.
Now referring to Fig. 3, in certain aspects, unloading is handled and can be installed the situation that receives data and represent described another device deal with data subsequently from another about a device.As represented by square frame 302, the input translator 206 (for example, transducer) of device 202 produces the data corresponding to transducer type among Fig. 2 A.For instance, in some embodiments, converter 206 can be suitable for sensing, and for example aural signature is (for example, sound, audio frequency, voice or music), the multimedia feature of both or both the above a certain combination in visual signature (for example, for example rest image of picture or for example mobile image of video) or the described feature to be to produce multi-medium data.In some embodiments, converter 206 can be suitable for the biological correlated characteristic of for example heartbeat of sensing, blood pressure, body temperature, oxygen concentration levels, G/W equality.In some embodiments, converter 206 can be suitable for for example surrounding environment correlated characteristic of pressure, temperature, speed, acceleration etc. of sensing.
In certain aspects, the sense data that is produced by converter 206 is the form of analogue data.This analogue data can be represented (for example) continuous wave (for example, voice data), discontinuous waveform (for example, heartbeat) or more discrete in essence information (for example, pressure, speed etc.).
As represented, install 202 preliminary treatment sense datas to be used for transmission by square frame 306.Discuss as mentioned, in some embodiments, preliminary treatment can relate to waveform coding institute sensed data (for example, the original analog data of being exported by converter 206).Herein, wave coder 210 can be carried out for example operation of the waveform coding of sigma-delta modulating-coding, pulse code modulated coding or some other appropriate formats.By analogue data is converted to digital form, can easily transmit original waveform data via the communication link that utilizes Digital Transmission.
Herein, should be appreciated that and to send data via communication link by high relatively data rate.For instance, be not that compressed data is sent to device 204, but can send data through overall pulse sign indicating number modulation format or to cross sampled form (for example, through the sigma-delta modulating data).Therefore, the routine techniques of the data that received with packed data before sending data via communication link (for example, uses sub-band coding in conjunction with bluetooth, MP3, or stereo coding) and decompression is compared, and the method that is disclosed can relate to less processing.For instance, for transmission, routine techniques can will be converted to through pulse code modulation data and can compress through pulse code modulation data before the transmission data through the sigma-delta modulating data.On the contrary, receiving terminal can relate to decompressed data to provide through pulse code modulation data or will be converted to through the sigma-delta modulating data through pulse code modulation data.
May need more wireless bandwidth although compare the method that is disclosed with the method for using compression, especially can the application of using relative high-bandwidth communication channel, can more effective transmission data application or both all can application in realize favourable compromise.For instance, in the application of using the ultra-wideband communications ultra broadband of pulse (for example, based on), realize favourable compromise.
The use of sigma-delta modulation also can promote the more reliable transmission of data via Radio Link.For instance, suppose that in the sigma-delta modulation signal each is actually least significant bit, can not have appreciable impact to institute's data recovered then for during the transmission losing of location.On the contrary, (for example, 16 PCM in) the scheme, losing of any one in the higher significance bit can have remarkable adverse effect to institute's data recovered through overall pulse sign indicating number modulating data sending via link.
But device 202 also preliminary treatment institute sensed data is to promote the reliable transmission via communication link.For instance, transmission pre-processing assembly 211 can provide chnnel coding, error coding, scrambling, interlock, formats or other similar signal processing.
As represented by square frame 308 and 310, transmitter 212 will be transferred to the receiver 214 of device 204 through pretreated data via wireless communication link.Device 204 can carry out subsequently some preliminary treatment complementary processing of carrying out with square frame 306 places with recover to produce in square frame 306 places through the waveform coding data.For instance, one or more processors 216 of device 204 can be carried out channel-decoding, error decoding, separate scrambling, release of an interleave, separate format or other similar operations.
As represented by square frame 312, on behalf of device 202, the processor 216 of device 204 can handle the data that received subsequently.For this reason, processor 216 can extract by at least one represented feature of the analogue data of institute's sensing.Discuss as mentioned, this can relate to the data reconstruction original analog data (for example, producing the data that the expression original waveform adds quantizing noise) from being received in fact.For instance, on behalf of device 202, processor 216 can derive through the sigma-delta modulating data, through pulse code modulation data or subsequently will be through the analogue data of further processing.

The unloading processing can be implemented in every way and be used to support various functional.In some embodiments, device one in 202 and 204 or both can optionally provide extra process.In some embodiments, described processing only will can be unloaded to device 203 by the part that device 202 is carried out originally.In some embodiments, can dynamical fashion carry out about whether unloading the decision-making of processing.Fig. 2 B illustrative system 200B, described system 200B have and comprise device 202B and the 204B that can be used for the some assemblies in for example described embodiment.Generally, Fig. 2 B assembly with or like symbol identical with Fig. 2 A assembly also can have identical or similar functions.
Discuss as mentioned, in some embodiments, the non-transmission relevant treatment of all of institute's sense data can be unloaded to wireless device 204.Yet in some embodiments, some are handled still and can be carried out by device 202.Therefore, as shown in Fig. 2 B, in certain aspects, device 202B can optionally comprise the processor 208 that is used to handle institute's sense data.
And for example above discuss, in some embodiments, all non-transmission relevant treatment that are sent to institute's sense data of device 202 can be unloaded to wireless device 204.Yet in some embodiments, some processing still can be carried out by peripheral unit.Therefore, as shown in Fig. 2 B, in certain aspects, device 202B can optionally comprise the processor 230 that is used to handle the data that received.
In some embodiments, device 202B can carry out some processing and other processing is unloaded on the device 204B.For instance, device 202B (for example, telephone headset) can have about MP3 decompression, echo elimination and the aborning one or more disposal ability of sidetone (for example, being provided by processor 230).As represented by line 246, processor 230 can receive some the information that is used in this processing (for example, sidetone produces) from input translator 206.In addition, device 204B (for example, mobile phone) can comprise that disposal ability is to provide one or more in the described operation.For instance, one or more processors 216B can comprise MP3 decompressor 248, sidetone processor 250 or echo eliminator 234.Therefore, decide on the requirement of given application, device 202B and 204B can be configured and make device 204B treat one or more from the operation of device 202B unloading from device 202B receiving sensor data with execution.
In some embodiments, can the dynamical fashion unloading handle.For instance, device 202B can detect device 204B and has in order to carry out the ability with the operation of the executable operation of device 202B (for example, MP3 decompress etc.) same type.Therefore, as long as device 202B communicates by letter with device 204B, then install 202B and can disconnect its circuit or inactive its processing functional and operative installations 204B.Therefore, when operating alone, device 202B can provide and himself handle (for example, crossfire does not have MP3 decompression ability from the MP3 music of quickflashing softdog (FLASH dongle)).In addition, if the electric charge on the battery of device 204B drops to below the critical point, then install 204B and can stop to provide unloading to handle (for example, decompression MP3 data) and alternately (for example untreatment data, compressed MP3 data) send to device 202B, install 202B by this and will carry out processing.Under another behaviour in service, device 202B (for example, the heart rate monitor transducer) can be at first treated sensing data (for example, measured heart rate) be sent to second device (for example, device can be the only watch of display message) with unloading relevant treatment ability.Subsequently, At All Other Times a certain, the device 202B untreated sensing data (for example, heartbeat waveform) can be sent to have suitable disposal ability (for example, heart rate detection) another the device 204B (for example, mobile phone).
On behalf of wireless device 202, the wireless device 204 of Fig. 2 A can carry out various types of operations.Fig. 5 explanation can provide the exemplary components in the embodiment of the some or all of signal processing that need carry out the data of being exported by wireless device 504 (for example, it can be similar to device 202) at wireless device 502 (for example, it can be similar to device 204).Herein, the form that device 502 can Wave data sends to device 504 with treated data.Therefore, device 504 can only be provided to the Wave data that is received for example suitable output device of converter.
With similar fashion as mentioned, device 502 can comprise communication processor 506, and described communication processor 506 can (for example) receive data via LAN, Wide Area Network or a certain other communication link.Communication processor 506 can optionally be handled (for example, decoding) data that received and go to the data of device 504 with extraction.
The gained data are provided to can represent device 504 data processor for processing data 508.Data processor 508 can comprise data decompressor 510, and described data decompressor 510 is decompressed data under the previous compressed situation of data.In addition, data processor 508 can comprise processor 512, and described processor 512 for example can provide the signal processing function of (for instance) decoding.In certain aspects, signal processing also can attempt to improve as institute's teaching herein by at least one represented feature of data.
In certain aspects, processor 512 can provide waveform processing functional to produce through the waveform coding data.For instance, with the similar fashion of being discussed as mentioned, processor 512 can produce through pulse code modulation data, through sigma-delta modulating data or a certain other form through the waveform coding data.
At device 504 places, receiver 518 is handled the data (for example, the similar fashion to be discussed as mentioned) that receive via link 516.Provide in the embodiment of waveform coding data at device 502, receiver 518 is exportable through the original waveform coded data.Waveform processor 520 can optionally handle subsequently received be provided to proper transformation device 522 (for example, loud speaker) through the waveform coding data and with described data.
In certain aspects, waveform processing can be advantageously used in and reduce device 504 needed treating capacities and install 504 power that consume.For instance, waveform processor 520 and converter 522 can comprise universal amplifier, D class A amplifier A or direct drive-type D class A amplifier A.Perhaps, in some embodiments, the sigma-delta data can be delivered to general D class A amplifier A unprocessedly.To discuss an embodiment of direct drive-type D class A amplifier A circuit in conjunction with Fig. 6 and Fig. 7 in more detail.
The exemplary aspect of the output translator circuit 600 that Fig. 6 explanation can directly be driven by the Wave data 602 that is received (for example, through the sigma-delta modulating data).Herein, output translator circuit 600 comprises direct drive-type D quasi-controller 604, described direct drive-type D quasi-controller 604 produces and (for example is used to control pair of switches 608A and 608B, transistor) control signal 606A and 606B, described switch is driven output translator 610 (for example, optionally via low pass filter 612) again.In certain aspects, directly drive-type D quasi-controller 604 can produce control signal 606A and 606B based on the difference of the duration that is associated with the Wave data 602 of varying level.For instance, referring to Fig. 7, what the generation time of control signal Q1 and Q2 (for example, control signal 606A and 606B) and width can be based between one and zero width of the continuous level among the sigma-delta modulation waveform data S (for example, Wave data 602) is poor.Therefore, the Wave data 602 that is received is driving transducer 610 and without undergoing for example attempting to improve by the processing of the signal processing of the represented feature of data or Wave data being converted to the processing of analogue data directly.By getting rid of this signal processing, wireless device (for example, device 504) is compared with the conventional equipment of not carrying out this signal processing and can be consumed less power.
Referring to Fig. 6 and Fig. 7, now will study the additional detail of the generation of control signal 606A and 606B once more.In some embodiments, control signal Q1 and the Q2 interval generation that can be associated in set with the continuous high level part (for example, having value " 1 ") of Wave data S and low level part (for example, having value " 0 ").Define an example of the described set of continuous high level and low level part by line W0, W2 and represented time cycle of W4.Time cycle W0 comprises time cycle P0 and P1, and wherein Wave data S is made up of succeeded by three continuous low level pulses five continuous high level pulses respectively.Similarly, time cycle W2 comprises time cycle P2 and P3, and wherein Wave data S is made up of four continuous high level pulses and five continuous low level pulses respectively.In addition, time cycle W4 comprises time cycle P4 and P5, and wherein Wave data S is made up of seven continuous high level pulses and three continuous low level pulses respectively.
In the example of Fig. 7, control signal Q1 and Q2 are based on the pulse of time cycle W0, W2 and W4 and produce.Specifically, (for example, time cycle W0 under the situation of) high level pulse number greater than the low level pulse number of described time cycle, can produce negative-going pulse in cycle preset time at signal Q1.On the contrary, under the situation of high level pulse number less than the low level pulse number of described time cycle in cycle preset time, can produce direct impulse at signal Q2.Therefore, in the example of Fig. 7, after time cycle W0 and W4, on signal Q1, produce pulse, and after time cycle W2, on signal Q2, produce pulse.
In certain aspects, the width of control impuls Q1 and Q2 is based on the pulse of time cycle W0, W2 and W4.What for instance, the width of control signal can be based between the high level pulse number in cycle preset time and the low level pulse number mouthful is poor.Therefore, in the example of Fig. 7, because time cycle P0 has five high level pulses and time cycle P1 has three low level pulses, so first pulse of control signal Q1 has the width of two pulses.Similarly, because time cycle P2 has four high level pulses and time cycle P3 has five low level pulses, therefore the pulse of the control signal Q1 after time cycle W2 has the width of a pulse.
Above embodiment advantageously provides the D type output that utilizes three-state control signal.For instance, equate that in continuous duration of the Wave data of level two control signals will disconnect under the situation of (for example, in the expression audio signal silent).Therefore, control signal can have the state of opening a switch, another state of opening another switch, and does not open the another state of arbitrary switch.By using this tristate technique, the power consumption of circuit 600 is can be in fact proportional by the volume and the significant level of the represented audio signal of Wave data 602 with (for example).
Should be appreciated that control signal Q1 and Q2 can produce based on other sequential relationship.For instance, in some embodiments, control signal Q1 and Q2 can produce based on the pulse collection that is associated with time cycle W1, W3, W5 etc.In addition, in some applications, control signal Q1 and Q2 can produce based on even number time window (W0, W2, W4 etc.) and odd number time window (W1, W3, W5 etc.), and the pulse output number on Q1 and the Q2 is doubled.Herein, the collision between effective Q1 and Q2 pulse may be more frequent; Therefore, can make dispositions in advance to guarantee not open simultaneously switch.
Can implement in every way to provide and be similar to above to be discussed functional direct drive-type D class A amplifier A circuit or a certain other similar circuit.For instance, in some embodiments, controller 604 can comprise pulse counter 614, the pulse number that described pulse counter 614 countings are associated with the Wave data 602 of each level.The gained counting can be sent to control impuls generator 616 subsequently, and described control impuls generator 616 produces control signal 606A and the 606B that is discussed as mentioned.In some embodiments, the up/down counter can be used for determining one and zero number difference in the continuous level of Wave data 602.Under this kind situation, the gained count value can be passed to another counter, and described counter counts downward produces control signal 606A and 606B by this with the pulse of output proper width.In certain aspects, output stage (for example, comprising switch 608A and 608B and converter 610) alternately comprises the H bridger, and described H bridger comprises two pairs of switches, and wherein each is coupled to the unique person in two input terminals of converter 610 to switch.
Discuss as mentioned, in some embodiments, Wave data can comprise through the multidigit pulse code modulation data.Under this kind situation, controller 604 can comprise the sigma-delta modulating coder, and described sigma-delta modulating coder will be converted to through sigma-delta modulating data (for example, the Wave data S of Fig. 7) through pulse code modulation data.
Teaching herein can be used with the pulse-width modulation scheme of other type.For instance, circuit 600 can be suitable for handling the Wave data (for example, the data that in time quantize) of taking multimode more to intend form.Therefore, controller 604 can be suitable for based on the pulse duration of Wave data 602 but not step-by-step counting (for example, " 1 " reaches " 0 ") produces control signal 606A and 606B.
Wave data can be represented any one in the various types of information.For instance, Wave data can be represented audio signal, various forms of sensing signal, RF signal or a certain other adequate information (for example, discussing as mentioned).

Under arbitrary situation, on behalf of device 202, device 204 can handle the data of its reception.In addition, device 204 can optionally be carried out other processing, as discussed herein.
In some embodiments, on behalf of device 202, the echo eliminator 234 of processor 216 can carry out echo and eliminate operation.For this reason, echo eliminator 234 can be handled from the data of installing 202 data that receive and positive transmission auto levelizer 202 to reduce any echo component that can be present in the data.
In some embodiments, on behalf of device 202, the active noise eliminator 236 of processor 216 can carry out initiatively noise cancellation operation.For this reason, initiatively noise eliminator can be handled and treat data of being exported by the converter (for example, telephone headset loud speaker) of device 202 and the data that produced by the input translator 206 (for example, surrounding environment microphone) that installs 202.In this way, initiatively noise eliminator 236 can add signal component to the data that just send to device 202, but described device 202 will be eliminated the ambient noise that log is heard by the user of device 202.
Should be appreciated that above a little example that only can represent the operation of device 202 execution, and should be appreciated that and to use other operation according to teaching herein for device 204.After device 204 was finished the processing of data, device 204 can send back to wireless device 202 (square frame 816) via Radio Link with treated data.Discuss as mentioned, in some embodiments, device 204 can make device 202 can more effectively export the data of wanting with send to device 202 through the waveform coding data.
