Specific embodiment
In below describing, in order to illustrate rather than in order to limit, it is proposed that such as particular system structure, interface, technology it
The detail of class, to cut thoroughly the present invention is understood.However, it will be clear to one skilled in the art that concrete without these
The present invention can also be realized in the other embodiments of details.In other situations, omit to well-known device, circuit and
The detailed description of method, in case unnecessary details hinders description of the invention.
Fig. 1 is a kind of schematic flow sheet of data transmission method provided in an embodiment of the present invention.
Specifically as shown in figure 1, the method includes：
Step 110, by data transmission channel I sub-channels are divided into.
Specifically, in order that oneself can be needed the data transfer of transmission by different data input sides when needing
Go out, and do not really want to rank, according to the mode of FIFO, when first to file takes the data input of data transmission channel
During square end of transmission, can transmit.So, data transmission channel can be divided into I sub-channels.Wherein, I sub-channels
Quantity is identical with the quantity of input data source, and the bandwidth of each sub-channels is input into according to input data source in I sub-channels
The occupied bandwidth weighted value q settings of data, wherein I is the positive integer more than or equal to 1.
Explanation is needed exist for, the quantity of subchannel is not changeless, and can be to send out as needed at any time
Raw change.For example, transmission data is finished now a data input side, then shared channel can also be released
Put, if now needing transmission data without data input side, then the subchannel that data transmission channel is divided is automatic
Subtract 1, then channel width then can be redistributed.Or, currently there is a new data input side to need to add, transmission data.
The occupied bandwidth weighted value q settings of the data that so bandwidth of subchannel is input into according further to input data source.
Each sub-channels in I sub-channels are respectively divided into K Channel Elements by step 120.
Specifically, each sub-channels in I sub-channels are divided into into K Channel Elements.Data are added to subchannel
When, can be unit according to Channel Elements, until when the data of each Channel Elements storage reach capacity, then change next letter
Road unit data storage.Wherein, K is the positive integer more than or equal to 1.
Step 130, will belong to the data of same input data source input according to the first predefined procedure add to the data
Cached in K Channel Elements of the corresponding subchannel of input source.
Specifically, the first predefined procedure here can be the order of FIFO.That is to say, successively according to data input
The order of source output data, data are added into subchannel corresponding with input data source.Different input data source correspondences
Be different subchannels.And each sub-channels, only store the number of currently input data source input corresponding with the subchannel
According to.Data are stored in K Channel Elements.
According to the input data source of the data that currently will be stored, corresponding subchannel is determined.For example, it is currently stored
Data are h datas, and the corresponding subchannel of the input data source belonging to h datas is i-th subchannel.So then will
H datas are input into into i-th subchannel.And be specifically input into into i-th subchannel which Channel Elements, then need into one
The determination of step.
Detailed process can include：
In oneainstance, when it is determined that i-th subchannel has created variables set corresponding with i-th subchannel, root
Whether it is more than total storage of k-th Channel Elements according to the currently stored data volume of k-th Channel Elements of storage h-1 datas
Data volume, determines that h datas add k-th Channel Elements, or h datas to add k+1 Channel Elements, wherein, become
The parameter set that quantity set is created when adding to i-th subchannel for the first data of input data source.And variables set can be at least
Including following parameter：The currently stored number of position indication information corresponding with k-th Channel Elements, k-th Channel Elements
According to amount, total data storage amount of k-th Channel Elements, and total data storage amount of i-th subchannel, wherein, wherein, i is
More than or equal to 1, and the positive integer less than or equal to I, h is the positive integer more than or equal to 2.K be more than or wait
In 1, and the positive integer less than or equal to K.
And whether k-th channel is more than according to the currently stored data volume of k-th Channel Elements of storage h-1 datas
Total data storage amount of unit, determines that h datas add k-th Channel Elements, or h datas to add+1 letter of kth
Road unit, specifically includes：
When k-th Channel Elements currently stored data volume less than k-th Channel Elements total data storage amount when, h
Data is added to k-th Channel Elements, and total data storage numerical quantity of i-th subchannel adds 1.
Or, when the currently stored data volume of k-th Channel Elements is more than or equal to total storage of k-th Channel Elements
During data volume, h datas add+1 Channel Elements of kth, and total data storage numerical quantity of i-th subchannel adds 1.
It is further preferred that because the weight of input side's input data occupied bandwidth is by being manually set.And in many feelings
It is under condition, such as different according to the data level of data input side's input, or, the input side of present input data is too many, before
The channel width that the allocated different pieces of information input side takes has set.But if readjust when can spend a large amount of
Between and energy.So, can also in a disguised form realize being accounted for during the low data input side's transmission data of priority level by another way
Reduced with bandwidth.The method is both the sub- letter when priority level is than channel transmission data shared by relatively low data input side
Local channel unit in road not data storage.The data total amount that is to say storage is zero.Therefore, at above-mentioned described k-th
Total data storage amount " full " of Channel Elements, and h datas are added before+1 Channel Elements of kth, it is necessary first to really
Whether the total data storage amount for determining+1 Channel Elements of kth is zero.Wherein, total data storage amount of Channel Elements is according to channel list
The occupied bandwidth weighted value of the data of the corresponding input data source input of subchannel belonging to first is calculated and obtained.Therefore, it is concrete to calculate
The formula of total data storage amount of+1 Channel Elements of kth is as follows：
wik+1=int (norm (qi))
Wherein, wik+1The data total amount of k-th Channel Elements storage of the sub-channels of kth+1；norm(qi) press equal to return
It is worth for qiThe random number being just distributed very much.
When it is determined that total data storage amount of+1 Channel Elements of kth is not zero, h datas are added into+1 letter of kth
Road unit.Or, when total data storage amount of+1 Channel Elements of kth is zero, h datas are added to+1 letter of kth
The Channel Elements that first total data storage amount after road unit is not zero.
In another scenario, the subchannel has for the first time input side to add data.It is possible to determine the subchannel also
Corresponding variables set is not created.That is to say that the input data source according to belonging to h datas determines and input data source
After corresponding i-th subchannel, it may be determined that i-th subchannel does not create corresponding variables set.So, it is necessary first to create
Variables set corresponding with i-th subchannel is built, then, it is determined that first total data storage amount is not zero in i-th subchannel
Channel Elements, and h datas are stored into into i-th subchannel the Channel Elements that first total data storage amount is not zero.
And h values now are in fact for 1.And i here is equally for more than or equal to 1 and just whole less than or equal to I
Number.The formula of the concrete total data storage amount for calculating Channel Elements is hereinbefore introduced, is repeated no more here.
Step 140, the data that different pieces of information input source is input into are sequentially output according to the second predefined procedure.
Specifically, the data that different pieces of information input source is input into are sequentially output according to the second predefined procedure specifically can wrap
Include：By the data in the k-th Channel Elements of each sub-channels in I sub-channels, it is sequentially output according to the second predefined procedure.
It is pre- according to second and the data in I sub-channels in (n-1)th Channel Elements of each sub-channels are all exported after finishing
The fixed data being sequentially sequentially output in n-th Channel Elements of each sub-channels in I sub-channels, wherein n be more than or
Positive integer equal to 2, and the initial value of n is 2.Specifically can be with as shown in Fig. 2 Fig. 2 be shown different pieces of information input source
Data are sequentially added to the schematic diagram of subchannel corresponding with input data source.Wherein, it is divided into multiple channel lists per sub-channels
First (such as 1～k in Fig. 2～k+1～n-1～n～K Channel Elements), because being predetermined according to second during by data output
Order is sequentially output the data of the same Channel Elements of different subchannels, that is to say the 1st column data in Fig. 2 preferentially according to second
Predefined procedure exports (column data output is finished, it is understood that finished for a wheel data output), followed by the 2nd column data is pressed
According to the output ... ... of the second predefined procedure, the (n-1)th column data is exported according to the second predefined procedure, and the n-th column data is predetermined according to second
Sequential output etc..And the second predefined procedure can be upper right falls down, or from down to up, do not limit here.It is then in Fig. 2
Sequential output from top to bottom.
And when the output of data whole is finished in arbitrary subchannel in above-mentioned I sub-channels, the method also includes：Step
150, data are all exported all parameters in the corresponding variables set of subchannel for finishing and is initialized.
Only upon initialization, the subchannel can then continue transport channel data input side needs the data of transmission.
And, initializing variable collection can also reduce the Installed System Memory shared by variables set.The live load of reduction system, further
Lift operating efficiency.
