It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

As shown in fig. 1, the method includes:
s110, after receiving a data synchronization triggering instruction, acquiring a first initial address, a first writing position and a first reading position corresponding to an original queue, and a second initial address, a second writing position and a second reading position corresponding to a mirror image queue; wherein the original queue matches the master and the mirrored queue matches the slave.
The data synchronization trigger instruction may refer to an instruction that triggers execution of data synchronization between heterogeneous units.
Wherein a master device may refer to one of the heterogeneous units in a heterogeneous architecture comprising a plurality of heterogeneous units. The original queue may refer to a buffer queue on the master side. The first initial address may refer to a data storage head address of the original queue. The first write location may refer to an address where the original queue may write the synchronized data during the current data synchronization process. The first read location may refer to an address where the original queue may read the synchronized data during the current data synchronization process.
Wherein a slave device may refer to another heterogeneous unit in a heterogeneous architecture comprising a plurality of heterogeneous units. The mirrored queue may refer to a slave-side buffer queue. The second initial address may refer to a data storage head address of the mirrored queue. The second write location may refer to an address where the mirror queue may write the synchronization data during the current data synchronization process. The second read position may refer to an address where the mirror queue may read the synchronized data during the current data synchronization process.
In an alternative embodiment, the method may further include: writing the data to be synchronized into an original queue through a main equipment software end; and updating a first writing position corresponding to the original queue through the master equipment software end and updating a second reading position corresponding to the mirror image queue through the slave equipment software end, and generating a data synchronization triggering instruction when data to be synchronized in the original queue meets a set synchronization requirement.
The software end may refer to a component triggering to realize data synchronization. The data to be synchronized may refer to data that needs to be data synchronized between two heterogeneous units, i.e., a master device and a slave device. Setting the synchronization requirement may refer to a condition under which the data to be synchronized is evaluated. For example, the set synchronization requirement may be a data accumulation amount of the data to be synchronized, or may be a data waiting time of the data to be synchronized.
Specifically, after the data to be synchronized is written into the original queue through the main equipment software end, the written position is updated to be the first written position corresponding to the original queue. Meanwhile, the slave device software end updates the second reading position corresponding to the mirror image queue after consuming the data in the mirror image queue according to the service execution flow, so that the follow-up data synchronization process can be realized smoothly. Further, whether the newly written data to be synchronized in the original queue reaches a set data accumulation amount or whether the data undetermined time of the data to be synchronized reaches a set time accumulation amount is judged, and when the data to be synchronized is accumulated to the set data accumulation amount or the data undetermined time of the data to be synchronized is accumulated to the set time accumulation amount, a data synchronization trigger instruction can be issued to the hardware acceleration unit to instruct to start the data synchronization process.
In an alternative embodiment, before the data to be synchronized is written into the original queue by the software end of the master device, the method further includes: constructing an original queue through a master device, caching and storing the original queue corresponding to the original queue into a first memory corresponding to the master device, and issuing a preset default instruction to a slave device; and receiving the preset default instruction by the slave device, constructing a mirror image queue according to the preset default instruction, and caching and storing the mirror image queue corresponding to the mirror image queue into a second memory corresponding to the slave device.

The default instruction may refer to a communication instruction pre-agreed between the master device and the slave device.

In the embodiment of the invention, the original queue cache can be regarded as an original queue, and the mirror queue cache can be regarded as a mirror queue, so that the understanding is convenient.
Specifically, after the master device stores the built original queue in the first memory corresponding to the master device, a preset default instruction is sent to the slave device to inform the slave device that a mirror image queue needs to be built, and after the slave device builds the mirror image queue and stores the mirror image queue in the second memory corresponding to the slave device, feedback is also carried out to the master device through the preset default instruction. Therefore, the construction of the original queue and the mirror image queue is completed, so that when the master device and the slave device perform data synchronization, only one buffer queue is not needed, and the execution efficiency of the heterogeneous unit is improved.

Wherein, the target synchronous data may refer to data that is finally synchronized from the original queue to the mirror queue. Typically, the target synchronization data is included in the data to be synchronized. The target length may refer to a data length of the target synchronization data.
Specifically, after determining the original data position and the original data size of the data to be synchronized in the original queue and the accommodating data position and the accommodating data size of the accommodating data in the mirror queue, the data relationship between the original data size and the accommodating data size can be utilized to determine the target length of the target synchronization data for final data synchronization, further, the target synchronization data with the target length is obtained from the original data position in the original queue, and the target synchronization data is synchronized to the accommodating data position of the mirror queue, so as to complete the data synchronization among heterogeneous units.
According to the technical scheme, after the data synchronization triggering instruction is received, the original data position and the original data size of the data to be synchronized in the original queue are determined according to the first initial address, the first writing position and the first reading position corresponding to the obtained original queue, the accommodating data position and the accommodating data size of the accommodating data in the mirror queue are determined according to the second initial address, the second writing position and the second reading position corresponding to the obtained mirror queue, further, the target length of the target synchronous data in the original queue is determined according to the data relation of the original data size and the accommodating data size, and the target synchronous data with the target length in the original data position in the original queue is synchronized to the accommodating data position of the mirror queue, so that the problem of low data synchronization efficiency among heterogeneous units is solved, rapid automatic data synchronization among the heterogeneous units can be realized, and the execution efficiency of the heterogeneous units is improved.
Example two
Fig. 2 is a flowchart of an automatic synchronization method for data between heterogeneous units according to a second embodiment of the present invention, where the method is based on the above embodiment, and in this embodiment, the method specifically includes the steps of determining an original data position and an original data size of data to be synchronized in an original queue according to the first initial address, the first writing position and the first reading position, and the method specifically includes: determining an original data position of data to be synchronized in an original queue according to a summation result of the first initial address and the first reading position; and determining the original data size of the data to be synchronized in the original queue according to the data comparison result of the first writing position and the first reading position and the numerical value calculation result of the first writing position and the first reading position. As shown in fig. 2, the method includes:
s210, after receiving a data synchronization triggering instruction, acquiring a first initial address, a first writing position and a first reading position corresponding to an original queue, and a second initial address, a second writing position and a second reading position corresponding to a mirror image queue; wherein the original queue matches the master and the mirrored queue matches the slave.
Specifically, after receiving the data synchronization triggering instruction, a first initial address, a first writing position and a first reading position corresponding to the original queue of the main equipment side, and a second initial address, a second writing position and a second reading position corresponding to the mirror image queue of the slave equipment side can be obtained, so that an effective basis is provided for subsequent data synchronization.
S220, determining the original data position of the data to be synchronized in the original queue according to the summation result of the first initial address and the first reading position.
Specifically, the first initial address of the original queue and the first read address are summed to obtain a summation result, and the summation result is used as an original data position of data to be synchronized in the original queue.
S230, determining the original data size of the data to be synchronized in the original queue according to the data comparison result of the first writing position and the first reading position and the numerical value calculation result of the first writing position and the first reading position.
The data comparison result of the first writing position and the first reading position may refer to a data size comparison result of the first writing position and the first reading position.
In an alternative embodiment, determining the original data size of the data to be synchronized in the original queue according to the data comparison result of the first writing position and the first reading position and the numerical calculation result of the first writing position and the first reading position includes: if the first writing position is higher than the first reading position, taking a first difference result between the first writing position and the first reading position as the original data size of the data to be synchronized in the original queue; if the first writing position is lower than the first reading position, determining the original data size of the data to be synchronized in the original queue according to a second difference result between the first queue size of the original queue and the first difference result.
The first difference result may refer to a difference result obtained by subtracting the first reading position from the first writing position when the first writing position is higher than the first reading position.
The first queue size may refer to an initial data storage length of the original queue. The second difference result may refer to a difference result between the first queue size, the first difference result, and a fixed word length when the first write location is lower than the first read location.
For example, if the first queue size is size1, the first write location is wptr1, the first read location is rptr1, and the fixed word length is 4. The first difference result = wptr 1-rptr 1; second difference result = size 1-wptr1+rptr1-4.
It should be noted that, since the original queue buffer corresponding to the original queue is a ring buffer, the first writing position higher than the first reading position may be understood as the first writing position being larger than the first reading position, however, after the buffer is cleared, the first writing position may be smaller than the first reading position, that is, may be understood as the first writing position being lower than the first reading position.
S240, determining the accommodating data position which can accommodate the data in the mirror image queue according to the summation result of the second initial address and the second writing position.
Specifically, the second initial address of the mirror image queue and the second writing position are subjected to summation processing to obtain a summation result, and the summation result is used as a data accommodating position capable of accommodating data in the mirror image queue.
S250, determining the size of the accommodating data which can accommodate the data in the mirror image queue according to the data comparison result between the second writing position and the second reading position and the numerical value calculation result between the second writing position and the second reading position.
The data comparison result between the second writing position and the second reading position may refer to a data size comparison result between the second writing position and the second reading position.
In an alternative embodiment, determining the size of the accommodating data in the mirror queue according to the data comparison result between the second writing position and the second reading position and the numerical calculation result between the second writing position and the second reading position includes: if the second writing position is lower than the second reading position, taking a third difference result between the second writing position and the second reading position as the accommodating data size of the accommodating data in the mirror image queue; and if the second writing position is higher than the second reading position, taking a fourth difference result between the second queue size of the mirror queue and the third difference result as the accommodating data size of the accommodating data in the mirror queue.
The third difference result may be a difference result obtained by subtracting the second reading position from the second writing position when the second writing position is lower than the second reading position.
The second queue size may refer to an initial data storage length of the mirror queue. The fourth difference result may refer to a difference result between the second queue size and the third difference result when the second write position is higher than the second read position.
Illustratively, if the second queue size is size2, the second write location is wptr2 and the second read location is rptr2. Third difference result = wptr 2-rptr 2; fourth difference result = size 2-wptr2+rptr2.
And S260, comparing the original data size and the accommodated data size in a numerical mode, determining a minimum numerical value, and determining the minimum numerical value as the target length of target synchronous data.
Where the minimum value may refer to smaller data between the original data size and the accommodated data size. Because the size of the original data in the original queue may be larger than the size of the accommodated data in the mirror queue, in order to ensure that the target synchronous data can be completely stored in the mirror queue, in the embodiment of the invention, the length of the target synchronous data needs to be determined so as to ensure the integrity of the data synchronization process.
S270, synchronizing the target synchronous data with the target length at the original data position in the original queue to the accommodating data position of the mirror image queue.
Specifically, after determining the target length of the target synchronous data, the target synchronous data with the target length can be obtained from the original data position in the original queue, and the target synchronous data is synchronized to the accommodating data position of the mirror image queue, so that the data synchronization among heterogeneous units is completed.
In an alternative embodiment, after synchronizing the target synchronization data of the target length at the original data location in the original queue to the accommodated data location of the mirror queue, the method further includes: sending a parameter updating signal to a target interrupt line; the parameter update signal includes an update read position corresponding to the original queue and an update write position corresponding to the mirror queue.
The target interrupt line may refer to an interrupt line corresponding to each of the heterogeneous units. Updating the read location may refer to the first read location updated after the original queue performs data synchronization. Updating the write location may refer to a second write location updated after the mirror queue performs data synchronization.
The parameter update signal may include an indication signal for updating the parameter after the data synchronization. Typically, after data synchronization, the first read location of the original queue and the second write location of the mirrored queue are automatically updated. In the prior art, the main device is generally required to always inquire the first reading position of the original queue, so that the use efficiency of the buffer queue is reduced, and therefore, the updated reading position corresponding to the original queue and the updated writing position corresponding to the mirror image queue can be sent to the interrupt line of each heterogeneous unit, so that the main device does not need to always inquire, and the use efficiency of the buffer queue is improved.
