Specifically, queue is a kind of special linear list, and it only allows to carry out deletion action in the front end of table, carries out insertion operation in the rear end of table.The end for carrying out insertion operation is referred to as tail of the queue, and the end for carrying out deletion action is referred to as team's head.In queue during no element, referred to as empty queue.In this data structure of queue, the element for inserting at first will be element deleted at first, otherwise the element being finally inserted will be the last element being deleted, therefore, queue is otherwise known as the linear list of " first in first out ".The storage mode of queue can be stored using linear list, it is also possible to stored using chained list.It is illustrative that the embodiment of the present invention carries out storage using chained list with queue.Wherein, chained list is a kind of discontinuous on physical memory cell, non-sequential storage organization, and the logical order of data element is realized by the pointer link orders in queue.Chained list is made up of a series of nodes (each element is referred to as node (node is referred to as node) in chained list), and node can be dynamically generated at runtime.Generally, each node includes two parts：One be storing data-elements data field (setting domain name as data), another is the pointer field (setting domain name as next) of the next node address of storage, and the information stored in pointer field is also called pointer or chain.Calculator memory space can be made full use of using list structure, flexible internal memory dynamic management is realized.

First queue in the embodiment of the present invention is used to manage information control node to be configured, during initialization, can distribute N number of information control node, inserts method by tail and is inserted in first queue, and N is more than or equal to 1.

In addition, in a step 101, the attribute information comprising voice data to be played in configured information control node.That is, according to corresponding voice data to be played when receiving triggering command, the information control node to be configured to unloading is configured, with the attribute information comprising voice data to be played in the information control node for postponing.It should be noted that above-mentioned triggering command can be threshold value interrupt instruction, or other can realize the operation of above-mentioned trigger action, to perform subsequent step according to the trigger action.

Step 102, configured information control node is linked in second queue and the 3rd queue.

Wherein, second queue and the 3rd queue is used to manage configured information control node.For second queue and the 3rd queue can be set to sky in initialization.

Step 103, from the 3rd queue unload unit data configured information control node.

In implementing, in three queue not empties, the configured information control node of unit data is unloaded from the queue heads of the 3rd queue.

Step 104, according to the attribute information of voice data to be played in the configured information control node of unloading, read corresponding voice data to be played.

Step 105, by unloading configured information control node be linked to the 4th queue.

Wherein, the 4th queue is used for the information control node for managing playing audio-fequency data.

The processing method of the voice data provided based on step 101- step 105，It is used for managing the first queue of information control node to be configured by setting，When threshold value down trigger，The information control node to be configured of unit data is unloaded from first queue，And the voice data to be played captured when being interrupted according to threshold value is configured to the information control node to be configured for unloading，Configured information control node is linked to for managing in the second queue and the 3rd queue of configured information control node，In three queue not empties，The configured information control node of unit data is unloaded from the 3rd queue，According to the attribute information of voice data to be played in the configured information control node of unloading，Play corresponding voice data to be played，And then the configured information control node of unloading is linked in management the 4th queue of the information control node of playing audio-fequency data.By the form of queue, the attribute information that playing audio-fequency data can be treated in real time is configured, and treat playing audio-fequency data and playing audio-fequency data has been managed respectively, simultaneously, according to configured information control node, corresponding voice data to be played is read, without the need for as prior art, voice data to be played is copied on other one piece of memory headroom, the problem brought by the voice data to be played on the memory headroom after copy is read.Using the technical scheme described in the embodiment of the present invention, while voice data to be broadcast will not be capped, before saving, the memory headroom of backup opening up and using, reject frequently impact of the memory copying to systematic function, eliminate internal memory alignment action and then streamline operation, evade the expense of memory pool realization, management and the later maintenance of complexity, simplify the problem that mentality of designing, the i.e. embodiment of the present invention realize that while avoiding and arranging memory pool voice data to be played will not be capped.

Embodiment two

On the basis of embodiment one, the embodiment of the present invention provides a kind of concrete implementation mode, as shown in Fig. 2 including：

Step 201, setting first queue, second queue, the 3rd queue and the 4th queue.

Wherein, first queue is used to manage information control node to be configured, and second queue and the 3rd queue are used to manage configured information control node, and the 4th queue is used for the information control node for managing playing audio-fequency data.It is convenient for subsequent descriptions, first queue is referred to as into tobe_pushed queues, second queue is referred to as pushed queues, and the 3rd queue is referred to as tobe_played queues, and the 4th queue is referred to as played queues.During initialization, distribute N number of information control node, method is inserted by tail and is inserted in tobe_pushed queues, N is more than or equal to 1；It is sky when pushed queues, tobe_played queues and played queue initializations.

It should be noted that, for the setting of first queue, second queue, the 3rd queue and the 4th queue, can be in initialization while be configured, or be configured when needing again, the embodiment of the present invention is illustrated as a example by being configured when in initialization simultaneously.

Step 202, voice data to be played is captured using direct internal memory write WDMA.

Wherein, direct internal memory write (Write Direct Memory Access, abbreviation WDMA) is corresponding with first buffering area, and first buffering area includes read pointer and write pointer.

In a preferred embodiment of the invention, first buffering area is buffer circle (Ring Buffer), the buffer circle includes write pointer (write pointer,) and read pointer (read pointer wpt, rpt), wherein, wpt represents the storage location of the voice data that captures in Ring Buffer, and rpt represents the storage location of the voice data in Ring Buffer of reading.Therefore, the audio capturing of WDMA and process work is mainly by its write pointer and read pointer to complete.Wherein, by WDMA oneself, write pointer mainly safeguards that read pointer is mainly by CPU controls.

Specifically, the logical relation schematic diagram of wpt, rpt of WDMA and its Ring Buffer of maintenance is shown with reference to Fig. 4.Wherein, st_addr (start address) represents the initial address (or first address) of Ring Buffer, and end represents the tail address of Ring Buffer.During initialization, wpt and rpt is 0, the i.e. initial address equivalent to correspondence Ring Buffer.When WDMA captures the voice data of place path, the voice data for capturing can be stored from the initial address of wpt, in addition, as the relief area is buffer circle, therefore, when wpt reaches the tail address of the Ring Buffer, the first address of Ring Buffer can be automatic jumped to, continue to start to store voice data from the original position of Ring Buffer, the memory space of the voice data for so being captured with the management of Ring Buffer formulas, the problem that the memory headroom that capture can be used for effectively solving is wasted, simultaneously, also eliminate the time restriction of audio capturing, support the audio capturing of Infinite Time length.

Whether the difference of write pointer and read pointer in step 203, detection first buffering area is more than or equal to the first predetermined threshold value.

Wherein, length of first predetermined threshold value less than first buffering area.Optionally, the size of the first predetermined threshold value can be set according to the length of Ring Buffer.Example, if the length of Ring Buffer is N*M, the first predetermined threshold value can be set to M, that is to say, that WDMA corresponding first buffering area is divided into into the relief area of N number of first preset threshold length.In addition, during initialization, the information control node of same number (i.e. N number of) can be distributed, method is inserted by tail and is linked in tobe_pushed queues.

If the difference of step 204, the write pointer and read pointer detected in first buffering area is more than or equal to the first predetermined threshold value, activation threshold value interrupts, and generates triggering command.

Step 205, the information control node to be configured that unit data according to triggering command, is unloaded from first queue, and the information control node to be configured to unloading configures.

In a preferred embodiment of the invention, step 205 specifically includes following sub-step：

205a, according to the threshold value interrupt, from first queue unload unit data information control node to be configured.

Wherein, mainly include following information in information control node to be configured：Place path, such as ATV Demod, AV, Component, VGA or HDMI；Channel number, such as 8 sound channels, 6 sound channels, 2 sound channels etc.；Sample rate, such as 32Khz, 35.15625Khz, 48Khz etc.；The initial address of voice data to be played；The data length of voice data to be played.

For the data structure of information control node to be configured can be defined as follows：

struct ListNode

{

int st_addr；The initial address of the corresponding voice data to be played of // information control node

int length；The length of the corresponding voice data to be played of // information control node

int sample_rate；The sample rate of // place path

int channel；// place path, ATV Demod, AV, Component, VGA, HDMI

int channel_num；// channel number, such as 8 sound channels, 6 sound channels, 2 sound channels

::

ListNode*next；// for generating the member of queue, that is, point to the corresponding next information control node of the information control node

}；

Of course, it is possible to according to actually required information, the data structure of information control node to be configured is deleted or increased, to meet the actual demand of user.

205b, according to the voice data to be played in first buffering area between read pointer to write pointer, the information control node to be configured to unloading is configured.

As first buffering area is buffer circle, therefore, it may appear that write pointer is more than the situation of situation and write pointer less than read pointer of read pointer.Specifically, with reference to shown in Fig. 5 and Fig. 6, wherein, Fig. 5 is situation of the write pointer more than read pointer, when write pointer is more than read pointer, then the voice data between read pointer to write pointer is [rpt, wpt] between voice data, the part as shown in Fig. 5 bends, and then according to [rpt, wpt] between voice data, to unload information control node to be configured configure；Fig. 6 is situation of the read pointer more than write pointer, and when write pointer is less than read pointer, then the voice data between read pointer to write pointer is：The voice data between tail address from read pointer to relief area and from the first address of relief area to the voice data write pointer, i.e. from [rpt, end] and [st_addr, wpt] two section audio data, the part as shown in oblique stroke in Fig. 6, and then according to [rpt, end] and [st_addr, wpt] two section audio data, the information control node to be configured of unloading is configured.

That is, during per subthreshold down trigger, according to the voice data to be played in first buffering area between read pointer to write pointer, the information control node to unloading is configured, with the attribute information comprising voice data to be played in the information control node for postponing.

Step 206, configured information control node is linked in second queue and the 3rd queue.

Wherein, attribute information comprising voice data to be played in configured information control node, initial address comprising corresponding voice data to be played, the length of voice data to be played in i.e. configured information control node, certainly, can also be comprising place path, sample rate, channel number etc. in configured information control node.

In implementing, as shown in fig. 7, by configured information control node link (chain) for receiving to pushed queues and the rear of queue of tobe_played queues.Wherein, the rear of queue that the configured information control node for receiving is linked to tobe_played queues is transmitted by deliver interfaces, meanwhile, information control node configured in pushed queues is yet suffered from.

Step 207, from the 3rd queue unload unit data configured information control node.

In concrete implementation, before execution step 207, first determine whether whether tobe_played queues are empty, if sky, then continue the afterbody (as shown in the tobe_played_tail in Fig. 7) of the configured information control node (as shown in the new_tobe_played_data in Fig. 7) of the voice data to be played that chain newly arrives to tobe_played queues；If non-NULL, then from the configured information control node of unchain unit datas in the 3rd queue, specifically from the configured information control node of queue heads (as shown in the tobe_played_head in 7) the unchain unit datas of tobe_played queues, now, the configured information control node of the new voice data to be broadcast for arriving may proceed to be linked to the afterbody of tobe_played queues.Wherein, unit data is preferably an information control node, voice data to be played corresponding with the information control node, alternatively referred to as a pen data.

Step 208, according to the configured information control node of unloading, the configuration node in the corresponding second buffering areas of RDMA is read to direct internal memory and is configured.

In implementing, the voice data from multiple passages can be stored in first buffering area (i.e. audio buffer), and the voice data in audio buffer belongs to voice data to be played.The embodiment of the present invention adopts RDMA (Read Direct Memory Access, directly internal memory reads) reading the voice data to be played in audio buffer, wherein, RDMA is actually reading DMA, DMA is easy to the communication between different hardware units, and need not rely upon a large amount of interrupt loads of CPU.

In implementing, RDMA has corresponding second buffering area buffer, second buffering area buffer includes write pointer (write pointer, wpt), read pointer (read pointer, rpt) and multiple configuration nodes item, each configuration node item has control information.The voice data read work of RDMA is mainly by its write pointer and read pointer to control what is completed.Wherein, write pointer mainly by CPU controls, safeguarded by RDMA oneself by read pointer.

In practice, for RDMA, IC (Integrated Circuit, that is integrated circuit) its corresponding relief area buffer can be embodied as a buffer circle, wherein, buffer circle is that a kind of data structure is used to represent fixed dimension, a relief area from beginning to end, and be adapted to data cached stream, a useful properties of buffer circle are：Its memory space can be recycled.

It is applied to the embodiment of the present invention, configuration node item that can the buffer circle is embodied as one by one, the item is primarily used to control RDMA reading voice datas, wherein, each item is made up of 64bit, first 32bit, i.e. first character, for initial address parameter start address (being abbreviated as st_addr), the physical address that RDMA PCM audio datas to be read are stored in internal memory is pointed to；Second 32bit, i.e., second word mainly include length parameter length member, and the length represents the length of the PCM audio data to be read.The relation of configuration node item of the write pointer, read pointer and buffer circle of RDMA is as shown in Figure 8, in buffer circle, read pointer points to configured good, to be read item in buffer circle, and write pointer is being configured or item to be configured in pointing to buffer circle.

It should be noted that the number of item is determined by CPU in buffer circle, the control information such as start address and lengh of each item, also by CPU real-time update.

In a preferred embodiment of the invention, step 208 specifically includes following sub-step：

Target configuration node pointed by 208a, the write pointer for determining in second buffering area.

In implementing, target item can be determined using two ways, one is to read the depositor corresponding to wpt, and corresponding item information is preserved in depositor；Two is that the item (if for 20) of RDMA is embodied as an Array for structural body, can obtain target item of wpt positions by the index corresponding to array wpt.

208b, the initial address that the initial address parameter of target configuration node is set to voice data to be played.

208c, the length that the length parameter of target configuration node is set to voice data to be played.

Specifically, after the embodiment of the present invention obtains target configuration node, configure the first character (i.e. initial address parameter) of target configuration node item, it is allowed to point to the physical address of the DDR that the voice data to be broadcast is located, it is reconfigured at second word (i.e. length parameter) of the item so as to store the length of the voice data to be played of the unit data.It should be noted that the length can preferably be the multiple of 128 bytes of hardware requirement.

Need explanation when, in order to the write pointer ensured in second buffering area has writeable item, read pointer has the item that can read, and then guarantee to be not in fast (i.e. the item of CPU configuration RDMA simultaneously updates its wpt) write, slow (the i.e. corresponding specified addresses of RDMA reading item read, the data of designated length simultaneously update its rpt) caused by sound jump the problem of (broadcast leakage) broadcast, and write it is slow, the problem of the fast caused sound interim card read, the difference of write pointer and read pointer in second buffering area can be calculated, if the difference of write pointer and read pointer is when meeting some requirements in second buffering area, the configured information control node of unit data is unloaded from the 3rd queue then, and corresponding item is configured according to the configured information control node of unloading.In addition, for write pointer in second buffering area and the difference of read pointer can be that write pointer is more than or equal to the 4th predetermined threshold value with the difference of read pointer meeting some requirements, 4th predetermined threshold value can be configured according to disposal ability of the number of item, CPU etc. in second buffering area, to meet actual demand, the set-up mode to the 4th predetermined threshold value of the invention is without limitation.

Step 209, according to the attribute information of voice data to be played in the configured information control node of unloading, read corresponding voice data to be played.

In a kind of preferred embodiment of the present invention, step 209 includes following sub-step：

209a, the write pointer updated in second buffering area.

As the corresponding second buffering areas of RDMA are buffer circle, therefore, step 209a includes：

209a1, judge that whether target configuration node is last configuration node of buffer circle.

If so, then execution step 209a2；If it is not, then execution step 209a3.

The position that 209a2, corresponding first configuration node of initial address that the write pointer if so, then configured in second buffering area is second buffering area are located.

209a3, if it is not, then configure second buffering area in write pointer be buffer circle in target configuration node close to next configuration node position.

Specifically, as RDMA is implemented as Ring Buffer, therefore, may determine that whether target item is last item in Ring Buffer, if target item is last item in Ring Buffer, the position that first item that its wpt is RDMA original positions is located is configured.Otherwise, configure the position of the back to back next item that its wpt is target item.

The difference of 209b, the write pointer and read pointer calculated in second buffering area.

If the difference of write pointer and read pointer in 209c, second buffering area is more than or equal to the second predetermined threshold value, the corresponding voice data to be played of configuration node pointed by read pointer is read.

As the wpt of RDMA is by CPU controls, its rpt is safeguarded by hardware oneself.Target item is configured above-mentioned, after have updated write pointer wpt, when the difference that have updated the rpt of wpt and RDMA of position is more than or equal to the second predetermined threshold value (such as 1 item), RDMA will read the voice data of the designated length in the corresponding core positions of item that its rpt is pointed to automatically, so, can ensure that now there is the configuration node that can be read, and then the voice data to be played corresponding to the configuration node that read pointer is pointed in reading second buffering area.When the difference of the wpt and rpt of RDMA is less than four predetermined threshold values, mean that the rpt in RDMA catch up with its wpt soon, CPU voice datas are reminded not enough to broadcast, need CPU to configure new item in time to point to new voice data to be played, in order to avoid occur due to temporary transient no data it is readable and occur sound interim card, or even it is noiseless the problems such as.Wherein, the 4th predetermined threshold value can be set according to the factor such as disposal ability of the number of item, CPU in second buffering area.Need explanation when, the 4th predetermined threshold value can be identical with the second predetermined threshold value, it is also possible to different.

Meanwhile, the RDMA of the embodiment of the present invention can also update read pointer rpt, and rpt is automatically updated to the position of the next item of rpt positions.As the buffer of RDMA is annular buffer, when its rpt goes to buffer afterbodys, the original position of the automatic ring to the buffer of meeting, and wpt then needs software maintenance to annular buffer heads, so as to recycle this section of memory headroom.

Step 210, by unloading configured information control node be linked in the 4th queue.

As shown in Figure 7, when the configured corresponding voice data attribute information to be played of information control node to unloading is carried out with postponing, by the rear of queue (as shown in played_tail in Fig. 7) of the node (as shown in new_played_data in Fig. 7) chain to played queues.

Technical scheme according to described by above-mentioned steps，After WDMA starts to capture voice data to be played，Every threshold interrupts，Information control node to be configured under queue heads unchain of tobe_pushed queues，Then corresponding [rpt is interrupted to the threshold,Wpt] between voice data to be played set up the control information (initial address of i.e. above-mentioned voice data to be played、Length、The information such as sample rate)，So，Information control node under tobe_pushed queue unchain just possesses these information，And it is interruption voice data to be played to be read that these information are corresponding，Then pushed queues receive (or docking) the information control node，And the deliver interfaces of rear end offer are provided，The interface is by the information control node to rear end，The rear of queue of its chain to tobe_played queue (is noted after receiving by rear end，Now the information control node is not unloaded from pushed queues)，Rear end RDMA starts receive data and gives power amplifier according to this，Need to call paly_item interfaces before broadcasting，The interface is from information control node under tobe_played queue heads unchian，The attribute information of the voice data to be played entrained by which is allocated to after the item of second buffering area corresponding with RDMA，By information control node chain to the played queue tails.

In order that information control node was unloaded and added on suitable opportunity, be beneficial to recycling for the information control node distributed during initialization, solve the problems, such as system memory space waste and implement frequently distribution information control node caused by memory fragmentation it is excessive.As shown in figure 3, the method also includes：

Step 211, the position for determining read pointer place in second buffering area.

Step 212, the difference for calculating the first mark pointer and the second mark pointer in second buffering area.

Wherein, the first mark pointer points to the position that a upper configuration node of the position that the read pointer in second buffering area is located is located, the position that the first mark pointer is located when the second mark pointer is last release.

If the difference of the first mark pointer and the second mark pointer is more than or equal to the 3rd predetermined threshold value in step 213, second buffering area, by the information control node unloading of configured between the first mark pointer and the second mark pointer in the 4th queue configuration node corresponding voice data played.

Wherein, the 3rd predetermined threshold value can be set according to disposal ability of the number of item, CPU etc. in second buffering area.

Further, while the information control node by the playing audio-fequency data in the 4th queue is unloaded or afterwards, as shown in figure 3, the method also includes：

Step 214, configured information control node corresponding with playing audio-fequency data in second queue is unloaded and discharged.

Step according to described by step 211-215, in concrete implementation, after a voice data is played, call play_item interfaces, by judging the first mark pointer and the second mark pointer, in the case where condition is met, played queues whether non-NULL is judged；If played queue not empties, the corresponding information control node of voice data has been broadcast for mono- from played queue heads unchain；Simultaneously，Due in the queue of second queue pushed comprising information control node corresponding with the voice data played，After the voice data to be played is played，By callback mechanism (readjustment realizing interface，The interface is used to complete the operation to information control node in tobe_pushed queues and pushed queues) information control node corresponding with the voice data played in pushed queues is unloaded，And discharge (release refers to the configuration information emptied in information control node)，And then it is linked to the rear of queue of tobe_pushed queues，So，The information control node that the fixed number distributed during initialization can be reached can move in circles the purpose for utilizing，Caused by solving the problems, such as system memory space waste and implementing frequently distribution information control node, memory fragmentation is excessive，Avoid the waste of system resource.

It should be noted that tobe_played queues are in the configured information control node for receiving that deliver interfaces pass over, the reason for do not unload the configured information control node from pushed queues it is：If now the configured information control node is unloaded from pushed queues, simultaneously by its chain to tobe_pushed queue, that means that tobe_pushed queues can use the information control node to formulate the voice data to be played on new core position, if front end is before the item of the attribute information to RDMA of the voice data to be played that tobe_played queue configuration informations control node in rear end is carried, the information control node is reconfigured, when RDMA reads the data in the new position and plays, it may appear that sound jumps the problem broadcast.Therefore it is to be ensured that the voice data on the corresponding DDR of the information control node is played, then which is unloaded from pushed queues, while the rear of queue of chain to tobe_pushed queues.

Further, as voice data is the voice data on different paths, therefore, when the voice data that voice data to be played is the first path, after step 209, as shown in figure 3, the method also includes：

216th, detect whether to be switched to alternate path from the first path.

If the 217, detecting from the first path and being switched to alternate path, remaining configured information control node in the 3rd queue is unloaded and discharges.

Second channel in the embodiment of the present invention different from first passage, detect switch to second channel from first passage when, unload and discharge remaining configured information control node in the 3rd queue.Specifically, because the voice data distributed before path switching, corresponding is the voice data in a upper path, and during the broadcasting of the voice data that path switching finishes the path for starting newly to be switched to, can first from tobe_played queue heads unchain next one node, if still there is the voice data of the last path not discharged in the queue, these voice datas can first be allocated to the item of RDMA, so as to RDMA first can read to walk the corresponding voice datas of these item, then the voice data for playing the new path of real-time configuration.Therefore, after path switching can be produced, the voice data for going up path residual for a moment, then the phenomenon for playing the voice data of the path being newly switched to first are played.The embodiment of the present invention is when each path switches, per in chain to tobe_played queues from queue heads to rear of queue can be allocated to the item of RDMA, the corresponding configured information control node of the i.e. remaining voice data do not played is unloaded and is discharged, with solve switched path when, first play go up for a moment a path remain voice data play again the path being newly switched to voice data problem.In addition, the action of the unloading and release is very fast, calculated with Millisecond, thus, the time for waiting passage switching of user can be substantially reduced, and then lift the audiovisual experience of user.
