Dma controller is a kind of peripheral hardware in internal system moving data, allows to hand between the hardware device of friction speed Data are changed, the operation of this data-moving is not rely on CPU, and dma controller can interrupt instruction by DMA and need by CPU The data of reason are in place.In addition, CPU only needs to establish DMA transfer, responding DMA interrupts, and handles dma controller and move The data of internal storage.

For single DMA transfer process, it is possible to specify 1 source address, 1 destination address and stride length, this stride Length is stride information, and after each write operation, the sum of current address and stride length are next time to be treatedlyly Location, this transmission with " normal " stride length are known as 1D transmission.

Referring to shown in Figure 1A, dma controller writes the data into first mesh after first source address A1 reading data Address B1.Then, source address A1 is added into stride length 1, obtains second source address A2, destination address B1 is added into stride Length 1, obtains second destination address B2, and dma controller writes the data into destination address after source address A2 reading data B2, and so on.

Referring to shown in Figure 1B, dma controller writes the data into first mesh after first source address A1 reading data Address B1.Then, source address A1 is added into stride length 2, obtains second source address A2, destination address B1 is added into stride Length 2, obtains second destination address B2, and dma controller writes the data into destination address after source address A2 reading data B2, and so on.

Compared with Figure 1A, in fig. ib, the stride length 1 of " normal " can be revised as to the stride length 2 of " improper ", So that 1D transmission can skip certain addresses, increase the flexibility of 1D transmission.

2D transmission is the extension of 1D transmission, is widely used in field of image processing.In 2D transmission process, it can relate to And following variable: X-direction counts configuration (X_COUNT), X-direction stride configuration (X_STRIDE), Y-direction counting configuration (Y_ COUNT), Y-direction stride configuration (Y_STRIDE).

2D transmission is a nested circulation, and interior loop parameter counts configuration by X-direction and the configuration of X-direction stride determines, outside Loop parameter counts configuration by Y-direction and the configuration of Y-direction stride determines, 1D transmits the interior circulation of corresponding 2D transmission.X-direction stride When configuration determines that each x is incremented by, the increased stride length in address；When the configuration of Y-direction stride determines that each y is incremented by, address increases Stride length；X-direction counts configuration and determines x number of increments；The configuration of Y-direction stride determines y number of increments.Moreover, Y-direction walks Width configuration can be negative, to allow dma controller address backrush in buffer (buffer area).

Referring to shown in Fig. 1 C- Fig. 1 F, the application scenarios for 1D-to-1D, 1D-to-2D, 2D-to-1D, 2D-to-2D are illustrated Figure, it is clear that the transmission process of above-mentioned 2D can enrich the application scenarios of DMA.

3D transmission is further expanding for 1D transmission, and can be related to following variable: X-direction counts configuration (X_COUNT), X Direction stride configures (X_STRIDE), Y-direction counts configuration (Y_COUNT), Y-direction stride configures (Y_STRIDE), Z-direction meter Number configuration (Z_COUNT), Z-direction stride configuration (Z_STRIDE).Wherein, 3D transmission is triple nested circulations, interior loop ginseng Number counts configuration by X-direction, the configuration of X-direction stride determines, middle layer loop parameter counts configuration by Y-direction, Y-direction stride is matched Decision is set, outer loop parameter counts configuration by Z-direction, the configuration of Z-direction stride determines.

Wherein, when the configuration of X-direction stride determines that each x is incremented by, the increased stride length in address；The configuration of Y-direction stride is determined When fixed each y is incremented by, the increased stride length in address；When the configuration of Z-direction stride determines that each z is incremented by, the increased stride in address Length；X-direction counts configuration and determines x number of increments；The configuration of Y-direction stride determines y number of increments；Z-direction counts configuration and determines z Number of increments.Moreover, the configuration of Y-direction stride can be negative, the configuration of Z-direction stride can be negative, to allow in buffer Middle address backrush.

It is extracted below in conjunction with the matrix of a 2D-to-2D, and the example being rotated by 90 °, the above process is illustrated.Ginseng As shown in Fig. 1 G, it is assumed that source matrix presses row sequential storage, and initial address A, purpose matrix by rows sequential storage, initial address is A', then: in data read process, source address A+7, X-direction counting is configured to 4, and X-direction stride is configured to 1, and Y-direction counts 4 are configured to, Y-direction stride is configured to 3, and Z-direction counting is configured to 0, and Z-direction stride is configured to 0.In data writing process, mesh Address be A'+3, X-direction counting is configured to 4, and X-direction stride is configured to 4, and Y-direction counting is configured to 4, the configuration of Y-direction stride It is -13, Z-direction counting is configured to 0, and Z-direction stride is configured to 0.

Referring to shown in Fig. 1 G, dma controller can read data from source address 0x1 (i.e. initial address A+7), and will read Data be written destination address 0x1 (i.e. initial address A'+3).Number is read from source address 0x2 (i.e. the direction 0x1+X stride configuration 1) According to, and destination address 0x2 (i.e. the direction 0x1+X stride configuration 4) is written into the data of reading.Data are read from source address 0x3, and Destination address 0x3 is written into the data of reading.Data are read from source address 0x4, and destination address is written into the data of reading 0x4。

By above-mentioned processing, in data read process, is read 4 times in X-direction, that is, reaches X-direction and count configuration 4, Therefore, a Y is executed, since Y-direction stride is configured to 3, source address 0x4 is added 3, obtains source address 0x5.It is write in data Enter process, read 4 times in X-direction, that is, reaches X-direction and count configuration 4, therefore, a Y is executed, since Y-direction stride is matched - 13 are set to, therefore destination address 0x4 is subtracted 13, obtains destination address 0x5.In conclusion data are read from source address 0x5, And destination address 0x5 is written into the data of reading；Then, data are read from source address 0x6, and purpose is written into the data of reading Address 0x6.Data are read from source address 0x7, and destination address 0x7 is written into the data of reading.Number is read from source address 0x8 According to, and destination address 0x8 is written into the data of reading.

It is read 4 times in data read process in X-direction by above-mentioned processing, that is, reaches X-direction and count configuration 4, therefore A Y is executed, in data writing process, is read 4 times in X-direction, that is, reaches X-direction and counts configuration 4, therefore execute primary Y, and so on, effect is referring to shown in Fig. 1 G.

Step 201, the first DMA is generated according to the characteristic information of input feature vector figure and reads configuration information and the configuration of the first DMA write Information, and determine that the 2nd DMA reads configuration information and the second DMA write configuration information.

Step 202, configuration information is read according to the first DMA, reads data from the input feature vector figure；And according to this first DMA write configuration information exports the data of reading to arithmetic logic.

Step 203, the operation result that configuration information reads arithmetic logic is read according to the 2nd DMA；And according to the 2nd DMA Configuration information is write, by the operation result storage of reading to output characteristic pattern.

In the above-described embodiments, input feature vector figure is initial characteristics figure, and dma controller can be read from input feature vector figure Data, that is, input feature vector figure is as source data.In addition, output characteristic pattern is target signature, dma controller can be by data It is written to output characteristic pattern.In conclusion dma controller reads data from input feature vector figure, and data are exported to operation Logic.Then, dma controller can read the operation result of arithmetic logic, and the storage of the operation result of reading is special to output Sign figure.

Wherein, it is the DMA configuration information for reading data from input feature vector figure that the first DMA, which reads configuration information, therefore, Configuration information being read according to the first DMA, data are read from input feature vector figure, this reading process, that is, from source address The process of data is read in (i.e. input feature vector figure).

Wherein, the first DMA write configuration information be for exporting data to the DMA configuration information of arithmetic logic, therefore, can Data to be exported to arithmetic logic according to the first DMA write configuration information, this writing process, that is, by the data of source address The process of destination address is written, so that data are moved from input feature vector figure to arithmetic logic, it is special to input by arithmetic logic The data levied in figure carry out operation.

Wherein, it is that the DMA configuration information for reading data from arithmetic logic therefore can be with that the 2nd DMA, which reads configuration information, The operation result that configuration information reads arithmetic logic is read according to the 2nd DMA.

Wherein, the second DMA write configuration information is that (i.e. the output of initial construction is special for storing data into output characteristic pattern Sign figure, in original state, is not written the data of arithmetic logic, in subsequent embodiment, the construction of introduction output characteristic pattern Journey) DMA configuration information therefore output characteristic pattern can be write data into according to the second DMA write configuration information, this is write Enter process, that is, by the process of the data write-in destination address of source address, so as to move data from arithmetic logic To output characteristic pattern.

Below in conjunction with concrete application scene, above-mentioned technical proposal is described in detail.It is to be directed under this application scene The implementation of Pooling (pond layer).Specifically, the effect of Pooling may include: the constant of holding input feature vector figure Property, this invariance includes translation, rotation and scale；Retain main feature and reduce parameter and calculation amount, prevents over-fitting, mention High model generalization ability.The most common pondization operation is average pondization and maximum pond, and average pond is for calculating image-region Average value, and using the average value as the value after pool area, maximum pond, and will for choosing the maximum value of image-region The maximum value is as the value after pool area.The region of pondization operation can be divided into 2x2,3x3, roi, global etc..Such as Fig. 2 B- It is convolution kernel size is 3x3 shown in 2G, the pooling schematic diagram that stride (stride) is 2.

If completing the carrying of this sliding window and the output of Pooling result by CPU, CPU will increase dramatically Burden.Based on this, the carrying of sliding window and the output of Pooling result can be completed by dma controller, to mitigate The burden of CPU is described in detail below in conjunction with Fig. 2 H.

Step 211, the characteristic information of input feature vector figure is obtained.Wherein, this feature information can include but is not limited to: input Width W, the height H of characteristic pattern, and the port number N including input feature vector figure.

Wherein, the width of input feature vector figure (i.e. Input Feature Maps) is W, is highly H, port number N is being deposited Coutinuous store in reservoir, initial address A.Therefore, the characteristic information of input feature vector figure may include including but is not limited to: input Width W, height H, the port number N of characteristic pattern.

Step 212, the first DMA is generated according to the characteristic information of input feature vector figure and reads configuration information and the configuration of the first DMA write Information, and determine that the 2nd DMA reads configuration information and the second DMA write configuration information.

Situation one generates the first DMA reading configuration information according to the characteristic information of input feature vector figure, comprising: dma controller can Configuration is counted to generate X-direction according to the width W of the input feature vector figure；Y-direction meter is generated according to the height H of the input feature vector figure Number configuration；The configuration of X-direction stride and the configuration of Y-direction stride are generated according to default value (such as 1).In addition, dma controller can be with Z-direction is generated according to the port number N of the input feature vector figure and counts configuration, and the configuration of Z-direction stride is generated according to default value.

For example, the example that the first DMA reads configuration information may include: that X-direction counts configuration: W；Y-direction counts configuration: H； X-direction stride configuration: 1；Y-direction stride configuration: 1.In addition, it can also include: Z-direction meter that the first DMA, which reads configuration information, Number configuration: N；Z-direction stride configuration: 1.

Certainly, it is an example that above-mentioned first DMA, which reads configuration information, reads configuration information with no restrictions to this first DMA, It can rule of thumb be configured, by taking above-mentioned first DMA reads configuration information as an example.

Situation two generates the first DMA write configuration information according to the characteristic information of input feature vector figure, comprising: dma controller can Configuration is counted to generate X-direction according to the width W and height H of input feature vector figure；Y-direction counting is generated according to default value to match It sets, the configuration of X-direction stride and Y-direction stride configure.Alternatively, dma controller can width W, height H according to input feature vector figure With port number N, generates X-direction and count configuration；And dma controller can generate Y-direction according to default value and count configuration, X The configuration of direction stride, the configuration of Y-direction stride, Z-direction count configuration, the configuration of Z-direction stride.

For example, the first DMA write configuration information includes: that X-direction counts configuration: W*H；Y-direction, which counts, to be configured: 0；X-direction step Width configuration: 0；Y-direction stride configuration: 0.Alternatively, the first DMA write configuration information may include: that X-direction counts configuration: W*H*N；Y Direction, which counts, to be configured: 0；X-direction stride configuration: 0；Y-direction stride configuration: 0；Z-direction, which counts, to be configured: 0；The configuration of Z-direction stride: 0。

Certainly, above-mentioned first DMA write configuration information is example, with no restrictions to this first DMA write configuration information, can be with It is rule of thumb configured, by taking above-mentioned first DMA write configuration information as an example.

It may include: X-direction counting configuration that situation three, the 2nd DMA, which read configuration information: 1；Y-direction, which counts, to be configured: 0；The side X It is configured to stride: 0；Y-direction stride configuration: 0.Alternatively, it may include: that X-direction counts configuration: N that the 2nd DMA, which reads configuration information,；Y Direction, which counts, to be configured: 0；X-direction stride configuration: 0；Y-direction stride configuration: 0；Z-direction, which counts, to be configured: 0；The configuration of Z-direction stride: 0。

Certainly, it is example that above-mentioned 2nd DMA, which reads configuration information, reads configuration information with no restrictions to this 2nd DMA, can be with It is rule of thumb configured, by taking above-mentioned 2nd DMA reads configuration information as an example.

Situation four, the second DMA write configuration information may include: X-direction counting configuration: 1；Y-direction, which counts, to be configured: 1；The side X It is configured to stride: 0；Y-direction stride configuration: 0.Alternatively, the second DMA write configuration information may include: that X-direction counts configuration: N；Y Direction, which counts, to be configured: 1；X-direction stride configuration: 0；Y-direction stride configuration: 0；Z-direction, which counts, to be configured: 0；The configuration of Z-direction stride: 0。

Step 213, configuration information is read according to the first DMA, reads data from the input feature vector figure.

Specifically, dma controller can read configuration information according to the first DMA, from the corresponding starting of input feature vector figure Address (such as initial address A) starts, and reads each data in the input feature vector figure.

Step 214, according to the first DMA write configuration information, the data of reading are exported to arithmetic logic.

Specifically, dma controller can be according to the first DMA write configuration information, from the corresponding entry address of arithmetic logic (such as entry address I) starts, and each data of reading are exported to arithmetic logic.

Step 215, the operation result that configuration information reads the arithmetic logic is read according to the 2nd DMA.

Specifically, can produce operation result, for example, operation is patrolled after data of the arithmetic logic to input carry out operation Collecting, which can be used for, carries out average value operation or maximum operation to continuous W*H data, wherein W and H is respectively input feature vector The width and height of figure.Therefore, operation result is the corresponding average value of continuous W*H data or maximum value.Further, Dma controller can read configuration information according to the 2nd DMA, from the corresponding exit address of the arithmetic logic (such as exit address O) Start, reads each operation result of arithmetic logic generation, such as 1 operation result or N number of operation result.

For example, being highly H, then input feature vector figure has W*H data, arithmetic logic pair if the width of input feature vector figure is W After continuous W*H data carry out average value operation or maximum operation, an available operation result, and according to second DMA reads configuration information and reads an operation result since the corresponding exit address of arithmetic logic.In another example if input feature vector The width of figure is W, is highly H, port number N, then input feature vector figure has W*H*N data, and arithmetic logic is to continuous W*H number After carrying out average value operation or maximum operation, available N number of operation result, and configuration information is read according to the 2nd DMA, Since the corresponding exit address of arithmetic logic, N number of operation result is read.

Step 216, according to the second DMA write configuration information, by the operation result storage of reading to output characteristic pattern.Specifically , dma controller can be according to the second DMA write configuration information, since the initial address of the output characteristic pattern, by reading The output characteristic pattern is arrived in each operation result storage.

For example, with reference to shown in Fig. 2 I, it is assumed that arithmetic logic is Pooling arithmetic logic, and Pooling arithmetic logic is Global (entirety) type, and Pooling arithmetic logic is used to carry out average value operation to continuous W*H data.Moreover, output The width of characteristic pattern is 1, is highly 1, port number N, in memory Coutinuous store, initial address B.In addition, Pooling The entry address of arithmetic logic is I, exit address O.Based on this, dma controller can realize global by two steps Pooling operation.

Data in input feature vector figure are exported and give Pooling arithmetic logic, transported by Pooling by the first step, dma controller It calculates logic and completes the operation averaged, for global pooling, corresponding 1 average value of every W*H input data Output, the N number of average value of final output.Second step, N number of average value that dma controller exports Pooling arithmetic logic, by suitable Sequence is stored to output characteristic pattern.In this way, operation is moved by two steps, in addition pooling arithmetic logic, can be achieved with global The function of pooling.

In one example, before the operation result storage to output characteristic pattern that will be read, it can also determine that input is special Sign schemes corresponding target DMA configuration information, and constructs output characteristic pattern according to target DMA configuration information.The output of this construction Characteristic pattern is the output characteristic pattern of original state, and there are no the data in write-in input feature vector figure, which can be Specific characteristic pattern is also possible to the characteristic pattern of full 0 or 1.In step 216, the output of this construction is exactly stored data into Characteristic pattern.After all data to be stored to the output characteristic pattern to this construction, so that it may obtain final output feature Figure.

Wherein, the example of the target DMA configuration information can include but is not limited to: X-direction counts configuration: N；Y-direction meter Number configuration: 1；X-direction stride configuration: 0；Y-direction stride configuration: 0；Z-direction, which counts, to be configured: 0；Z-direction stride configuration: 0；Its In, N is the port number of input feature vector figure.

Certainly, above-mentioned target DMA configuration information is an example, with no restrictions to this target DMA configuration information, can be with Rule of thumb configured, it is herein above state target DMA configuration information for.

Wherein, output characteristic pattern is constructed according to target DMA configuration information, comprising: dma controller construction size is 1*1*M Output characteristic pattern；Wherein, output characteristic pattern is full 0, initial address B.

Wherein, output characteristic pattern is constructed according to target DMA configuration information, comprising: dma controller is read from designated storage location Specific style information is taken, and according to target DMA configuration information, constructs output characteristic pattern corresponding with the specific style information.Into One step, according to target DMA configuration information, construct output characteristic pattern corresponding with the specific style information, comprising: DMA control Device constructs the output characteristic pattern of full 0 according to the target DMA configuration information.It is, of course, also possible to construct complete 1 output characteristic pattern.

In convolutional neural networks, data-moving task can be realized using dma controller, and is no longer realized using CPU Data-moving task.It, should referring to shown in Fig. 3 A, being the example of the flow chart of above-mentioned data processing method in convolutional neural networks Method can be applied to dma controller, and this method may include:

Step 302, configuration information is read according to the first DMA, reads the first data from the first input feature vector figure；According to this First DMA write configuration information exports the first data of reading to arithmetic logic.

Step 303, configuration information is read according to the 2nd DMA, reads the second data from the second input feature vector figure；According to this Second DMA write configuration information exports the second data of reading to arithmetic logic.

Step 304, the operation result that configuration information reads arithmetic logic is read according to the 3rd DMA；According to the third DMA write Configuration information, by the operation result storage of reading to output characteristic pattern.
