Description
Technical Field
The present invention relates to data storage, and more particularly, to a method for saving parameters and an electronic device.
Background
As shown in fig. 1, the parameters inside the device are generally organized into a tree structure according to the internal logical classification. Parameter 1 is the root of all parameters; parameter 13 is the parent node of parameter 132; parameter 132 is a child of parameter 13; the bottom-most parameter 1111 is a leaf node.
In a special case, the parameters may also be organized into a "forest" shape, where there are a plurality of root nodes, as shown in fig. 2.
In general, the parameters of the electronic device are stored completely (all parameters have a corresponding entry on the memory chip), and are stored in a fixed order (e.g., all leaf nodes are left to right).
In general, parameters are adjacent to each other on a memory chip and have no idle space.
When storing parameters, most of the parameters are stored with leaf nodes, and binary values are stored in a non-compression mode.
The traditional parameter storage method has the following defects:
a) when software is upgraded, newly added parameters are inconvenient. Particularly, one item is additionally arranged in the middle of the leaf node, so that the storage influence is large. The prior art solutions store the data in the storage space in a certain fixed order. When a new parameter is added, the new parameter is often added at the end of the original parameter; unless a storage space is reserved in the original parameters, the space is not necessarily completely enough, and the use efficiency of the storage space is affected. Over time, the logical relationship of the parameter classification hierarchy becomes chaotic.
b) When the software is upgraded, the original parameters are not convenient to delete. After the original parameters are deleted, the space can not be recovered, and the storage space still needs to be occupied.
c) All parameters can only receive operation and are stored all at once; some parameters cannot be saved and some parameters are saved.
d) Most of the parameters are stored in plain text, which is not beneficial to protecting the parameters.

s1, storage modes, wherein each parameter can select four different storage modes: default mode, manual preservation, automatic preservation and non-preservation;
wherein,
the default mode is as follows: the storage mode is the same as that of the father node;
and (3) manual preservation: storing when issuing an explicit storage command;
automatic preservation: if the parameters are modified, the parameters are stored at regular time, and if the parameters are modified, the parameters are stored at intervals of a certain time;
and (3) no preservation: real-time status, no need to save;
s2, a single parameter storage mode, wherein each stored parameter is divided into a parameter path, a separator and a parameter value;
s3, storing all leaf node parameters according to a certain ordered sequence in a parameter storage mode;
s4, after the parameters are continuously modified, the formed disorder is stored;
s5, compressing and encrypting the parameters, wherein the parameters are compressed and encrypted before being stored; after the parameters are read, decryption and decompression are carried out;
s6, storing multiple groups of parameters respectively and independently, when the parameters are divided into several groups, organizing the groups into forest-shaped structures, and independently selecting whether each group of parameters is compressed or not and whether the parameters are encrypted or not;
s7, multiplexing the stored parameters with the external interface commands, and when the user operates or communicates with other devices, the communication data format adopts the same form as the parameter storage format, thereby improving the multiplexing capability.
As a further improvement of the present invention, in step S1, the root node parameter can only be selected from three storage modes, i.e., manual storage, automatic storage, and non-storage.
As a further improvement of the present invention, in step S1, the following are automatically saved: if the parameters are modified, the parameters are stored regularly, and if the parameters are modified, the parameters are stored once every 30 seconds.

Detailed Description
The invention is further described with reference to the following description and embodiments in conjunction with the accompanying drawings.
A method of parameter preservation comprising the steps of:
1. storage mode
In the method, each parameter can select four different storage modes: default mode, manual save, automatic save, no save. The root node parameters can only be the last 3 modes.
The default mode is as follows: the same way as the father node is kept.
And (3) manual preservation: and saving when an explicit saving command is issued.
Automatic preservation: if the modification is carried out, the timing is saved. If there is a parameter modification, it is stored every 30 seconds.
And (3) no preservation: real-time status, no need to save.
As shown in fig. 3, if the parameter 1 is set to the "auto save" mode and all other parameters are set to the "default mode", all other data samples are finally set to the "auto save" mode.
As shown in fig. 4, the parameter 1 is set to the "auto save" mode, the parameter 111 is set to the "no save" mode, the parameter 13 is set to the "manual save" mode, and all the other parameters are set to the "default mode". The final parameters 11, 12, 112 are set to "auto save" mode; parameter 1111 is set to "not save" mode; the parameters 131, 132, 1321, 1322, 1323 are set to the "manual save" method.
2. Storage mode of single parameter
In the method, each stored parameter is divided into a parameter path, a separator and a parameter value.
As shown in fig. 5, the parameter path includes the names of all nodes on the shortest path from the root node parameter to the leaf node parameter, separated by some delimiter (e.g., "/").
As shown in fig. 5, the parameter value is a specific value of the leaf node parameter.
As shown in FIG. 5, the parameter path is separated from the parameter value by a separator (e.g., ":').
3. Parameter storage mode
When all leaf node parameters are stored in a certain order (e.g., from left to right), the result is shown in FIG. 6.
4. Out-of-order storage formed after parameters are continuously modified
Assume that the device is operating initially without parameters 1321 and 131. When the leaf node parameters are stored in a certain order (e.g., from left to right), the result is shown as (1) in fig. 7.
After the subsequent software upgrade is updated, the parameter 1321 and the parameter 131 are added successively, and the latter of the former parameters exists, as shown in (2) and (3) in fig. 7 respectively.
Namely, in the device, the mapping relationship between the parameter logic classification relationship and the sequence in the memory chip is not invariable. If not from left to right, all leaf node parameters are saved in sequence.
5. Parameter compression and encryption
As shown in fig. 8, before (after) the parameters are stored (or read), the parameters may be compressed and encrypted (decrypted and decompressed) first (or later), so as to reduce the occupied storage space and improve the security.
6. Multiple sets of parameters are stored independently
When the parameters are divided into several groups (organized into forest-shaped structures), each group of parameters can be independently selected whether to be compressed or encrypted, as shown in fig. 9.
7. Storage parameter multiplexing with external interface-pressing command
As shown in fig. 10, when the user operates or communicates with another device, the communication data format of the external interface 3 may be in the same form as the parameter storage format, thereby improving the multiplexing capability.
As shown in fig. 10, an electronic device includes a processor 100, a memory chip 200, and an external interface 300, wherein the processor 1 is connected to the memory chip 200 and the external interface 300, respectively, and the memory chip 200 stores parameters according to any one of the above-mentioned parameter storage methods.
The electronic device may be an embedded device, such as a digital audio matrix, with a memory chip 200 (e.g., Flash, E2 PROM) in the device itself; in the using process of an end user, the equipment parameters can be modified; the device parameters modified by the user need to be saved; the equipment parameters are more and more complex; the memory chip 2 (e.g. Flash) is limited in capacity, e.g. not more than 64 MByte. All the parameters are organized according to tree shapes and forest shapes. Four different storage modes can be selected for each parameter: default mode, manual save, automatic save, no save. The root node parameters can only be the last 3 modes. Each stored parameter mainly comprises a parameter path (composed of names of a plurality of parameters) and a parameter value. The mapping relationship between the parameter logic classification relationship and the sequence in the memory chip in the device is not invariable. For example, the logical classification of the parameters during the operation of the device is from left to right, and the order of the parameters of the storage chip (e.g., Flash) may be the time order of the random modification of the parameters by the user. Before (after) the parameters are stored (or read), the parameters can be compressed (after) and encrypted (decrypted and decompressed), so that the occupied storage space is reduced, and the safety is improved. When the user operates or communicates with other devices on the external interface 300, the communication data format can adopt the same form as the parameter storage format, thereby improving the multiplexing capability.
The parameter saving method and the electronic device provided by the invention have the following advantages that:
a) when the software is upgraded, the new parameters are convenient to add. The newly added parameter can be put at the end of saving, but when the program runs, because of the path of the parameter, the parameter can still be classified and saved according to the original relation. Even if one item is newly added in the middle of the leaf node, the storage is not influenced. Even if a program modifies many parameters, the hierarchical relationship of the classification of the parameters can be maintained.
b) The parameters can be classified, partially saved, partially not saved, automatically saved at regular time, manually saved and the like.
c) The real-time status of the device may be set to not be saved and organized with the associated parameters in the neighborhood of the parameter tree. Therefore, developers and end users can understand more easily, the research and development threshold of the equipment can be reduced, and the usability is improved.
d) And (3) improving the consistency of the program: the configuration instructions are consistent with the peripheral control instructions. When the user operates or communicates with other equipment on the external interface, the communication data format can adopt the same form as the parameter storage format, thereby improving the multiplexing capability.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
