Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.
Fig. 1 is a schematic structural diagram of a non-volatile storage medium provided in the present application, where the non-volatile storage medium may be, but is not limited to: nand flash memory, NOR flash memory. Referring to fig. 1, the nonvolatile storage medium includes: a controller 101 and a storage unit 102.
The controller 101 controls the storage unit 102 to read and write data, erase data, and retrieve data pages. The number of the memory cells 102 is at least one.
Taking the case that the nonvolatile storage medium executes the GC policy in the prior art as an example, fig. 2 is a schematic diagram of a capacity of the nonvolatile storage medium provided in the present application, and as shown in fig. 2, when the available space value of the storage unit 102 is less than or equal to a first preset space threshold, that is, the remaining space capacity is less than the first remaining space capacity, the recovery of valid data pages and the erasure of invalid data blocks are performed until the available space value is greater than or equal to a second preset space threshold, that is, the remaining space capacity is greater than or equal to a second remaining space capacity.
Alternatively, in the related art GC strategy, when the GC start condition as shown in fig. 2 is satisfied, the GC function is performed. Fig. 3 is a schematic diagram of a nonvolatile storage medium provided by the present application for performing a GC function, and with reference to fig. 1, a controller 101 controls a storage unit 102 to recover valid data pages and erase invalid data blocks, as shown in fig. 3, block1 is a data block to be subjected to the GC function. Data pages a and B are valid data pages and the remaining data pages are invalid data pages. And carrying the effective data pages A and B in the data block1 to a new data block2, and erasing the data block1 to obtain a data block11 after the recovery of the effective data pages is completed. The data block11 may be used to carry a data page.
Current GC strategies typically employ an idle time trigger mechanism, i.e., performing GC functions when there is no data read. However, the execution of the GC function must be completed until the available space capacity reaches the stop waterline, and when data reading is required, the recovery of the valid data page occupies the bus bandwidth, which affects the read-write data and causes the continuous read-write performance to be degraded.
In view of the above problems, the following embodiments of the present application provide a technical solution, the core improvement point of which is to set the recovery and pause conditions when the GC function is executed, that is, to execute the GC function according to the data read/write and the available space.
In the following, a technical solution of the present application is described with reference to a specific embodiment, fig. 4 is a schematic flowchart of a data processing method for a nonvolatile storage medium according to an embodiment of the present application, where the schematic flowchart may be executed by the controller 101 corresponding to fig. 1, and as shown in fig. 4, the method includes:
s201, obtaining a first operation parameter value of the storage unit. The first operating parameter value characterizes data read-write performance of the memory cell.
S202, when the first operation parameter value meets the recovery condition, recovering the valid data page in the invalid data block.
And S203, when the first operation parameter value does not meet the recovery condition, not recovering the valid data page.
And when the first operation parameter value of the nonvolatile storage medium meets the recovery condition and the GC function is executed, if the first operation parameter value does not meet the recovery condition, the valid data page is not recovered, and the bus bandwidth is made available for data reading and writing.
In the data processing method for the nonvolatile storage medium provided by this embodiment, when the nonvolatile storage medium executes the GC function, that is, the valid data page is recovered, a suspension condition is satisfied, and the recovery of the valid data page can be suspended. And the GC function is suspended, so that the bus bandwidth is given up for data reading and writing, the continuous performance of data reading and writing is ensured, and the working efficiency of the nonvolatile storage medium is ensured.
Optionally, the first operating parameter value comprises: a first IOPS value and a first bandwidth value. IOPS (Input/Output Operations Per Second) is the number of reads and writes Per Second. The first IOPS value is the total number of data reads and writes of the nonvolatile storage medium per second, the first bandwidth value is a bandwidth occupied by data read and write, the first IOPS value and the first bandwidth value are introduced to provide a parameter for determining whether to execute or suspend the GC function, a possible implementation manner for executing the GC policy is given below based on the first IOPS value and the first bandwidth value, specifically, on the basis of fig. 4, fig. 5 is a schematic flow diagram of a data processing method of the nonvolatile storage medium provided in another embodiment of the present application, as shown in fig. 5, S202 includes:
s202-1, when the first IOPS value is smaller than a first preset IOPS value and the first bandwidth value is smaller than the first preset bandwidth value, recovering the erasure of the valid data page and the invalid data block.
Alternatively, fig. 6 is a schematic diagram of the number of data read/write times of the nonvolatile storage medium, as shown in fig. 6, 1 second is divided into n pieces, and then the number of read/write times of each piece is recorded. In fig. 6, the ordinate IO represents the number of times of reading and writing per chip, the abscissa T represents time, and the first IOPS value is calculated as follows:
wherein the IOPS is the calculated IOPS value.
Fig. 7 is a schematic diagram of data flow of a nonvolatile storage medium, as shown in fig. 7, the data flow of each slice is recorded after dividing 1 second into n slices. In fig. 7, the ordinate BW represents the data flow per chip, the abscissa T represents the time, and the calculation of the first bandwidth value is as follows:
wherein BWPS is the calculated bandwidth value.
N is an integer of 1 or more, for example, n is 100, that is, 1 second is divided into 100 pieces. By dividing each second into n pieces, the first IOPS value and the first bandwidth value can be accurately detected, and accurate triggering and pausing of GC can be ensured.
When the first IOPS value is smaller than the first preset IOPS value and the first bandwidth value is smaller than the first preset bandwidth value, the bus bandwidth occupied by data reading is smaller, and the total bandwidth is enough to support the memory unit to simultaneously read and write data and recycle the effective data page.
When the first IOPS value is smaller than the first predetermined IOPS value and the first bandwidth value is smaller than the first predetermined bandwidth value, the GC function may be executed as long as there are valid data pages to be recycled.
With continuing reference to fig. 5, S203 includes:
s203-1, when the first operation parameter value meets the pause condition, pausing the recovery of the valid data page.
S203-1, comprising: and when the first IOPS value is larger than the second preset IOPS value or the first bandwidth value is larger than the second preset bandwidth value, the recovery of the valid data page is suspended.
It should be noted that, when the first IOPS value is greater than the second predetermined IOPS value or the first bandwidth value is greater than the second predetermined bandwidth value, the bus bandwidth is not sufficient to support data reading and writing and recovery of the valid data page at the same time, and therefore, recovery of the valid data page needs to be suspended, and the bus bandwidth is set aside for data reading and writing, so as to ensure continuity of data reading and writing.
Optionally, fig. 8 is a graph of a first bandwidth value and a first IOPS value of the non-volatile storage medium according to an embodiment of the present disclosure, as shown in fig. 8, where the first predetermined IOPS value is equal to the second predetermined IOPS value, and is denoted by y1 in fig. 8. The first preset bandwidth value is equal to the second preset bandwidth value, which is denoted by x1 in fig. 8. When the first IOPS value is smaller than the first predetermined IOPS value y1 and the first bandwidth value is smaller than the first predetermined bandwidth value x1, that is, in the area a shown in fig. 8, the GC function is executed to recover the valid data page. When the first IOPS value is greater than the first predetermined IOPS value y1, or the first bandwidth value is greater than the first predetermined bandwidth value x1, that is, in the area C shown in fig. 8, the recycling of the valid data page is suspended.
Optionally, fig. 9 is a graph of a first bandwidth value and a first IOPS value of a non-volatile storage medium according to another embodiment of the present disclosure, as shown in fig. 9, a first preset IOPS value is represented by y1, a second preset IOPS value is represented by y2, a first preset bandwidth is represented by x1, and a second preset bandwidth is represented by x2. The first preset IOPS value y1 is smaller than the second preset IOPS value y2, and the first preset bandwidth value x1 is smaller than the second preset bandwidth value x2. The B areas between the first preset IOPS value y1 and the second preset IOPS value y2 and between the first preset bandwidth value x1 and the second preset bandwidth value x2 are buffer areas. When the first IOPS value is smaller than the first predetermined IOPS value y1 and the first bandwidth value is smaller than the first predetermined bandwidth value x1, that is, in the area a shown in fig. 9, the erasure of the valid data page and the invalid data block is recovered, and then the detected first IOPS value is larger than the first predetermined IOPS value y1 but smaller than the second predetermined IOPS value y2, and/or the first bandwidth value is larger than the first predetermined bandwidth value x1 but smaller than the second predetermined bandwidth value x2, that is, in the area B shown in fig. 9, the erasure of the valid data page and the invalid data block is still recovered.
Similarly, when the first IOPS value is greater than the second predetermined IOPS value y2, or the first bandwidth value is greater than the second predetermined bandwidth value x2, i.e., in the region C shown in fig. 8, the recycling of the valid data pages and the erasing of the invalid data blocks are suspended, and then the detected first IOPS value is greater than the first predetermined IOPS value y1 but less than the second predetermined IOPS value y2, and/or the first bandwidth value is greater than the first predetermined bandwidth value x1 but less than the second predetermined bandwidth value x2, i.e., in the region B shown in fig. 9, the recycling of the valid data pages and the erasing of the invalid data blocks are still suspended.
Setting the buffer area can prevent switching of the state of the nonvolatile storage medium caused by temporary fluctuations in the IOPS value and the bandwidth value of data reading and writing. Resulting in poor GC recycling or data read-write continuity.
Optionally, on the basis of fig. 4, this embodiment provides another possible implementation manner for executing the GC policy, where the first operation parameter value includes: fig. 10 is a schematic flow chart of a data processing method of a non-volatile storage medium according to another embodiment of the present application, as shown in fig. 10, S202 includes:
s202-2, when the available space value is smaller than or equal to a first preset space threshold value, judging whether the read-write types of the plurality of continuous data are all read data types.
S202-3, if not, recovering the valid data page and erasing the invalid data block.
Referring to fig. 2, if the available space value is less than or equal to the first preset space threshold, the number of data blocks that can be used for writing is small, which affects normal reading and writing of data. Therefore, the GC function is executed, and the valid data pages are recycled for data writing, so that the data reading and writing efficiency of the nonvolatile storage medium is ensured.
It should be noted that, when the first IOPS value is greater than the second preset IOPS value, or the first bandwidth value is greater than the second preset bandwidth value, and the available space value is less than or equal to the first preset space threshold value, even if the GC function is suspended to make the bandwidth available for data reading and writing, since the number of data blocks available for writing is small, the reading and writing performance of the nonvolatile storage medium is still affected, in this case, the GC function should be executed to recover the valid data pages.
With continuing reference to fig. 10, S203 includes:
and S203-2, when the available space value is greater than or equal to a second preset space threshold value, suspending the recovery of the valid data pages and the erasure of the invalid data blocks. The second preset spatial threshold is greater than the first preset spatial threshold.
Referring to fig. 2, if the available space value is greater than or equal to the second preset space threshold, the number of the available data blocks can ensure normal data writing, and at this time, the recovery of the valid data page and the erasure of the invalid data block are suspended, so that the bus bandwidth is set aside for data reading and writing, and the efficiency of data reading and writing is ensured.
Optionally, continuing with fig. 10, S203, includes:
s203-3, if the read-write types of the plurality of continuous data are all read data types, acquiring the number of the plurality of continuous data.
S203-4, if the number is larger than the preset number, acquiring a second operation parameter value. The second operating parameter value characterizes data read performance of the memory cell.
When data is read, data writing does not need to be carried out by using the data block. And if the detected number of the plurality of continuous data is larger than the preset number, determining that the data is continuously read.
S203-5, when the second operation parameter value meets the pause condition, pausing the recovery of the valid data page.
If the data is continuously read and the second operation parameter value meets the pause condition, the recovery of the data page can be paused, the bandwidth is made available for reading the data, and the continuous performance of data reading is ensured.
Optionally, one possible implementation manner of S203-5 is:
and if the second IOPS value is larger than a third preset IOPS value or the second bandwidth value is larger than a third preset bandwidth value, suspending the recovery of the effective data page.
It should be noted that the second IOPS value is the number of data reads per second, and the second bandwidth value is the bandwidth value occupied by data reads.
Alternatively, the second IOPS value may be calculated by formula (1) in the above embodiment, and the second bandwidth value may be calculated by formula (2) in the above embodiment.
Alternatively, when the data write is detected, the continuous data read is interrupted, and the recovery of the suspended valid data page is resumed as a recovered valid data page.
Optionally, when no reading of the data is detected, when the first IOPS value is greater than the second preset IOPS value or the first bandwidth value is greater than the second preset bandwidth value, the suspending of the recycling of the valid data page may be resumed as recycling the valid data page.
It should be noted that, in the above embodiment, after the GC function is executed, the method further includes erasing the recovered invalid data block after recovering the valid data page in the invalid data block. When the GC functionality is suspended, it also includes suspending erasure of the failed data blocks.

the recovery module is specifically configured to, when the first IOPS value is smaller than a first preset IOPS value and the first bandwidth value is smaller than a first preset bandwidth value, read and write data and recover the valid data page at the same time;
the recovery module is specifically configured to determine whether the read-write types of the multiple continuous data are all read data types when the available space value is less than or equal to a first preset space threshold; and if not, recycling the valid data page.
