Referring to fig. 2, fig. 2 is a flowchart of a data storage method applied to the electronic device 100 of fig. 1, and the method includes various steps described in detail below.
The data storage method provided by the embodiment is applied to a processor of an electronic device, and the electronic device further comprises a system chip, wherein the system chip comprises the processor.
Step 201: and in the running process of the electronic equipment, segmenting the memory space of the system chip to obtain a plurality of first memory segments.
Step 202: and determining a first memory segment to which the data to be reserved belongs as a first target memory segment.
The data to be reserved are data meeting preset conditions.
Step 203: when a restart operation occurs, the type of the restart operation is determined.
Step 204: and refreshing a plurality of other first memory segments except the first target memory segment when the type of the restarting operation is hot restarting.
Step 205: temporarily storing the data to be reserved from the first target memory segment to at least one other first memory segment after the refreshing is completed, and refreshing the first target memory segment.
Step 206: after the refreshing of the first target memory segment is completed, the data to be retained is migrated from at least one other first memory segment to the refreshed first target memory segment.
In the continuous operation process of the electronic equipment, in order to avoid that when the restarting operation occurs, the system chip of the electronic equipment directly refreshes data to cause data loss, the electronic equipment segments the memory space of the system chip to obtain a plurality of first memory segments. And determining the data meeting the preset conditions as the data to be reserved, and determining a first target memory segment to which the data to be reserved belongs.
It should be specifically noted that, when the memory space of the system chip is segmented, it is required to ensure that the storage space of the segmented first target memory segment can meet the requirement of storing the data to be reserved, that is, the storage space of the first target memory segment is greater than or equal to the data amount of the data to be reserved.
For example, the data to be reserved may be important data of the user, where the data to be reserved may be data configured by the user, or may be data of an important result calculated in the operation process of the electronic device, or other valuable data.
For the determination mode of the data to be reserved, based on the preset field, in the continuous operation of the electronic device, searching the data consistent with the preset field from all the data operated by the system chip as the data to be reserved. Or based on the requirement of the user, determining the data consistent with the requirement of the user from all the data operated by the system chip as the data to be reserved. The method for determining the data to be reserved is not particularly limited in the embodiment of the present application.
When the electronic equipment is restarted, the type of the restarting operation is judged, the type of the restarting operation can be divided into cold restarting and hot restarting, and the cold restarting indicates that the electronic equipment is powered on to restart after power is turned off. The hot restart indicates that the device is not powered down to restart.
When the restart operation is judged to be hot restart, the data to be reserved is temporarily stored to other first memory segments by refreshing the other first memory segments except the first target memory segment, after the refreshing of the other first memory segments is finished, and after the refreshing of the first target memory segment is finished, the data to be reserved is migrated to the original position, namely the data to be reserved is migrated to the first target memory segment, so that the important data can be reserved under the condition that other storage media are not added, and when the hot restart operation is carried out, the data loss is avoided.
It should be noted that, the refreshing of at least one other first memory segment and the first target memory segment actually performs the initialization processing on the data in at least one other memory segment and the first target memory segment, that is, the data emptying is completed.
In another example, during operation of the electronic device, the memory space of the system chip is segmented to obtain a plurality of first memory segments, when a restart operation occurs and when the restart operation is judged to be a hot restart, whether the plurality of first memory segments contain data to be reserved or not is judged, if yes, a first target memory segment to which the data to be reserved belongs is determined, refreshing is performed on a plurality of other first memory segments except the first target memory segment, the data to be reserved is temporarily stored from the first target memory segment to at least one other first memory segment after the refresh is completed, the first target memory segment is refreshed, and after the refresh of the first target memory segment is completed, the data to be reserved is migrated from at least one other first memory segment to the first target memory segment after the refresh is completed. And when judging that the first memory sections do not contain the data to be reserved, refreshing all the data in the system chip according to the existing mode.
Various implementations are provided for temporarily storing the data to be retained from the first target memory segment to at least one other first memory segment after the refresh is completed, and in one implementation, as shown in fig. 3, the method includes the following steps:
step 205-1: and respectively determining the storage spaces of the other first memory sections after the refreshing is finished.
Step 205-2: and determining the data quantity of the data to be reserved.
Step 205-3: and determining the arrangement sequence of other first memory segments.
Step 205-4: and sequentially inquiring according to the arrangement sequence, and determining a target memory segment with the storage space larger than or equal to the data volume from other first memory segments.
Step 205-5: and temporarily storing the data to be reserved into the target memory segment.
For example, when the memory space of the system chip is segmented into a plurality of first memory segments, the numbers are the first memory segment, the second memory segment, and the third memory segment, respectively, and the second memory segment is determined to be the first target memory segment. The other first memory segments except the first target memory segment are a first memory segment and a third memory segment, the storage spaces of the first memory segment and the third memory segment are respectively determined, and the data quantity of the data to be reserved is determined. And determining that the arrangement sequence of the first memory segment and the third memory segment is the first memory segment and the third memory segment, comparing the data volume of the data to be reserved with the storage space of the first memory segment, and temporarily storing the data to be reserved into the first memory segment when the storage space of the first memory segment is larger than or equal to the data volume of the data to be reserved. When the storage space of the first memory segment is smaller than the data amount of the data to be reserved, comparing the data amount of the data to be reserved with the storage space of the third memory segment, and when the storage space of the third memory segment is larger than or equal to the data amount of the data to be reserved, temporarily storing the data to be reserved into the third memory segment.
The implementation manner of determining the arrangement sequence of the other first memory segments may be: determining the time when refreshing of each other first memory segment is completed; and ordering the other first memory segments based on the time sequence to obtain the arrangement sequence of the other first memory segments.
When the data to be reserved is temporarily stored in the first memory segment, after the first target memory segment is refreshed, the data to be reserved is migrated from the first memory segment to the first target memory segment. When the data to be reserved is temporarily stored in the third memory segment, after the first target memory segment is refreshed, the data to be reserved is migrated from the third memory segment to the first target memory segment.
In another example, when the storage space of the first memory segment is smaller than the data amount of the data to be reserved, the target data may be determined from the data to be reserved based on the selection operation of the user, and the target data may be stored in the first memory segment. It should be noted that, the data size of the target data is smaller than the data size of the data to be reserved.
In another implementation of temporarily storing the data to be retained from the first target memory segment to at least one other first memory segment after the completion of the refresh, as shown in fig. 4, the method includes the following steps:
step 205-6: and when the data volume is larger than the storage space of each other first memory segment, acquiring a preset number of target memory segments from the plurality of other first memory segments.
Step 205-7: and determining the sum of the storage spaces of the preset number of target memory segments.
Step 205-8: the amount of data is compared to the sum of the storage spaces.
Step 205-9: and when the data volume is smaller than or equal to the sum of the storage spaces, temporarily storing the data to be reserved into each target memory segment.
For example, when the memory space of the system chip is segmented into a plurality of first memory segments, the numbers are the first memory segment, the second memory, the third memory segment and the fourth memory segment, respectively, and the third memory segment is determined to be the first target memory segment. The other first memory segments except the first target memory segment are a first memory segment, a second memory segment and a fourth memory segment, the storage spaces of the first memory segment, the second memory segment and the fourth memory segment are respectively determined, and the data quantity of the data to be reserved is determined. And when the data quantity of the data to be reserved is larger than the storage space of the first memory section, the storage space of the second memory section and the storage space of the fourth memory section, and the preset quantity is set to be 2, the first memory section and the second memory section are obtained as target memory sections, the storage spaces of the first memory section and the second memory section are added to obtain a storage space sum, and when the data quantity of the data to be reserved is smaller than the storage space sum, the data to be reserved is temporarily stored in the first memory section and the second memory section.
When the data to be reserved are temporarily stored in the first memory segment and the second memory segment, after the first target memory segment is refreshed, the data to be reserved are migrated from the first memory segment and the second memory segment to the first target memory segment.
In another example, when the sum of the storage spaces indicates that the sum of the storage spaces is the storage space of the first memory segment and the second memory segment, when the data amount of the data to be reserved is greater than the sum of the storage spaces, the first memory segment, the second memory segment and the fourth memory segment are obtained as the destination memory segment, the sum of the storage spaces of the first memory segment, the second memory segment and the fourth memory segment is calculated, and when the data amount of the data to be reserved is less than the sum of the storage spaces, the data to be reserved is temporarily stored in the first memory segment, the second memory segment and the fourth memory segment.
When the restart operation occurs, there are various implementation manners for judging the restart operation, and in one implementation manner, as shown in fig. 5, the method includes the following steps:
step 203-1: when a restart operation occurs, it is determined whether data can be acquired from the dynamic random access memory.
Step 203-2: if the data can be obtained from the dynamic random access memory, the type of the restart operation is determined to be a hot restart.
Step 203-3: if the data cannot be acquired from the dynamic random access memory, the type of the restarting operation is determined to be cold restarting.
The electronic device further includes a dynamic random access memory communicatively coupled to the processor. Because the dynamic random access memory is not powered down during the hot restart, the data stored on the dynamic random access memory cannot be lost, and after the hot restart of the system, the dynamic random access memory can use the data before the restart. When cold restarting, the data stored on the dynamic memory is lost after the dynamic memory is powered down, so the type of restarting operation can be judged based on the state of the data acquired by the dynamic random memory.
In another implementation of determining the restart operation, as shown in fig. 6, the method includes the following steps:
step 203-4: when a restart operation occurs, the lock state of the system chip is acquired.
Step 203-5: the type of restart operation is determined based on the lock state of the system chip.
Wherein, different lock states correspond to different restart operation types.
