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 102 at device 104 and comprise the example of discussing the unloading processing for the situation of the embodiment of the telephone headset of wireless device tout court.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 the elimination of active noise.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.

Device 104 is handled original sense data and is eliminated so that (for example) equilibrium of being wanted, equalizer tap weight calculation, echo elimination or active noise to be provided together with other input data.Under the situation of audio player, other input data can comprise treats the data (for example, audio volume control) that played out by telephone headset 102.These input data can be produced or can be received from another device via communications component 128 by device 104.

Device 104 will treated data, and (for example, the data of eliminating through the data of equilibrium, tap weight, through echo, the data eliminated through noise) are transmitted and are later worn electrophone 102 or a certain other destination.In last situation, telephone headset 102 can be provided to loud speaker 132 with the treated data that receive subsequently.Herein, should be appreciated that can carry out fast enough the operation above discussed with provide echo initiatively to eliminate, initiatively noise is eliminated or the processing of a certain other type.

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 the ox sense data with (for example).Fig. 4 is about being transferred to data the operation of another device of output data 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 and in given embodiment, can not use one or more in the operation of discussing herein.

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 specific description herein variety of way implement herein teaching.Therefore, in other embodiments, device 202 can not be 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 information (for example, pressure, speed etc.) in essence.

As represented by square frame 306, install 202 preliminary treatment sense datas to be used for transmission.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 ∑-Δ 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 ∑-Δ modulating data).Therefore, with packed data before sending data via communication link (for example, used the band coding in conjunction with bluetooth, MP3, or stereo coding) and the routine techniques of the data that receive of decompressing compare, the method that discloses 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 ∑-Δ 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 ∑-Δ modulating data through pulse code modulation data.

May need more wireless bandwidth although compare the method that discloses 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 ∑-Δ modulation also can promote data via the more reliable transmission of Radio Link.For instance, suppose that in ∑-Δ 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.

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 with untreatment data (for example, 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 watch that only shows information) 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).

The wireless device 204 of Fig. 2 A can represent wireless device 202 and carry out various types of operations.Fig. 5 explanation can provide the exemplary components in the embodiment that need handle the some or all of signals that the data of being exported by wireless device 504 (for example, it can be similar to device 202) are carried out 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 receives 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 receive and go to the data of device 504 with extraction.

The gained data are provided to and 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 handle 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 ∑-Δ modulating data or a certain other form through the waveform coding data.

Transmitter 514 can be transferred to device 504 via suitable communication link 516 with treated data subsequently.Discuss as mentioned, data can untreated in fact form transmission.For instance, transmitter 514 can transmit uncompressed still 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 receive 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, ∑-Δ 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 exemplified aspect of the output translator circuit 600 that Fig. 6 explanation can directly be driven by the Wave data 602 that receives (for example, through ∑-Δ modulating data).Herein, output translator circuit 600 comprises direct drive-type D quasi-controller 604, described direct drive-type D quasi-controller 604 produces for (for example controlling 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 ∑-Δ modulation waveform data S (for example, Wave data 602) is poor.Therefore, the Wave data 602 that receives is driving transducer 610 and without undergoing for example attempting to improve the processing of being handled by the signal of the represented feature of data or the processing that Wave data is converted to analogue data directly.Handle by getting rid of this signal, 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 again.In some embodiments, control signal Q1 and the Q2 interval generation that can be associated in the 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 ").Defined 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 at signal Q1 in cycle preset time.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, produce pulse at signal Q1, and after time cycle W2, produce pulse at signal Q2.

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 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 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 to guarantee not open simultaneously switch in advance.

Can implement in every way to provide and be similar to above 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 discusses 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 ∑-Δ modulating coder, and described ∑-Δ modulating coder will be converted to through ∑-Δ 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).
