Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
Fig. 1 is a flowchart of a method for implementing storage management according to an embodiment of the present invention, as shown in fig. 1, including:
step 100, when data editing is carried out, determining whether an idle page exists in an eflash space of an embedded nonvolatile memory for storing data;
step 101, when determining that an eflash space has an idle page, editing data on the idle page;
the data editing method comprises the following steps: data upload or data update.
After the idle page is determined, data editing is performed on the idle page, repeated erasing and writing of the previously stored page are avoided when the idle page exists, the probability that each bit is written in and erased is balanced, and the service life of the eflash space is prolonged.
Optionally, when data editing is performed, the method according to the embodiment of the present invention further includes:
adding writing record information of using state information and data editing on all pages of the eflash space through reserved addresses;
wherein the usage state information includes: used, unused, dirty pages;
the writing of the recording information is for data reading, including: a page code or a distinguishing character corresponding to data is previously set.
It should be noted that the reserved address may be a fixed address in each page, for example, a byte at the end position of each page; the use state information can be obtained through related technologies, the preset page code can be a logic code, and page codes corresponding to different kinds of data can be set; the page code includes a digital code that can distinguish the writing of data. Similarly, the distinguishing characters include characters which can distinguish different kinds of data and distinguish writing sequence of various kinds of data. The erasure operation of the eflash takes a page as a unit, and when a system sends a command to write or update certain data; if the data is written, adding writing record information in a preset identification address in the page after the data is written, and accurately reading the written data according to the writing record information record and the identification of the page written with the data and the writing position of each byte of the data; if the data is updated, the position of the data stored in the previous time is determined according to the writing record information, and the data is updated through the determined position of the data stored in the previous time. Because the content added in the identification address needs to be erased and written repeatedly and needs to be prevented from losing due to power failure, the content needs to be written in the eflash space, and because the content corresponds to the page, the identification address is set on the page for content addition.
In addition, the embodiment of the invention can read data according to the mapping relation by establishing the page coding or distinguishing the mapping relation between the characters and the page numbers of the page.
Optionally, the method in the embodiment of the present invention further includes: adding the following part or all of information on the reserved address:
the header, version information of the edited data.
It should be noted that the identification head may include an identification head designed by using related technologies, for example, an identification for identifying the application of the embodiment of the present invention to the eflash space. Version information of the edited data may be determined according to the number of times the data is updated.
Taking the eflash space size of 2K and the page size of 512bytes as an example, when performing storage management, 12bytes are reserved at the end of the page as a reserved address for storing an identification header, use state information, write record information, and version information of edited data; FIG. 2 shows data structure information added at the reserved address, in 12bytes at the end of the page in the used page, of the 12bytes at the end of the page, 1 to 3 bytes are identification headers, 4 bytes are use status information (unused, used, dirty page), 5 to 8 bytes are version information of the edited data, and 9 to 12bytes are write record information according to the embodiment of the present invention; wherein, the writing record information may be preset page coding.
Optionally, before data editing is performed on an idle page, the method according to the embodiment of the present invention further includes:
and subtracting the occupied space of the identification address from the total storage space of the page to obtain the storage space for data editing in the page.
It should be noted that, after subtracting the occupied space of the identification address, the data amount actually written in each page is determined, when writing according to the logical address, the writing position of each byte of the data can be determined, and when only partial data is updated, the byte of the data that needs to be updated can be determined, and then the partial byte is replaced. Fig. 3 is a schematic diagram of a storage space for editing in a page according to an embodiment of the present invention, as shown in fig. 3, since a reserved address is used to add an identification header, usage status information, write record information, and/or version information of edited data, addresses available for data writing in the page are reduced, and still taking a page size of 512bytes as an example, in a page of 512bytes, 12bytes are used as the reserved address, and only 500 bytes per page can be used to set a logical address for data writing and reading.
Optionally, the data editing on the idle page in the embodiment of the present invention includes:
and writing the edited data into the free page according to the logic address of the written data and the determined storage space for data editing in the page.
It should be noted that the logical address may be a fixed address that has been set in the related art, and after the logical address and the storage space for data editing in the page are determined, the data may be written into the free page byte by byte. When reading, the location of data storage can still be analyzed and read according to the logical address and the storage space for data editing in the page.
Optionally, when the data editing is data updating, the data editing on the idle page in the embodiment of the present invention includes:
copying the data stored at the previous time into a preset cache page;
and after updating the data copied into the cache page, writing the updated data into the determined free page.
Here, the data stored at the previous time is data that needs to be updated;
optionally, after data editing is performed on an idle page, the method according to the embodiment of the present invention further includes:
setting the page where the data stored at the previous time is located as a dirty page, and setting the write record information of the dirty page as invalid information.
It should be noted that, here, setting the write record information of the dirty page as invalid information may include: and setting the writing record information of the dirty pages as a default value, or setting the writing record information of the dirty pages as null, or deleting the writing record information of the dirty pages.
Optionally, when determining that there is no idle page in the eflash space, the method in the embodiment of the present invention further includes:
and erasing the data on the dirty pages to obtain the free pages.
It should be noted that a dirty page is an existing definition in the related art, and even if the usage status information is not added, the embodiment of the present invention may determine whether a page in the eflash space is a dirty page through the related art. Only when no free page exists, uniform erasing processing is carried out, and the data erased and written in each page are balanced.
