Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
The present invention will be described in detail below with reference to the accompanying drawings.
Fig. 2 shows a flowchart of an encoding method for a configuration file according to an embodiment of the present invention, and fig. 3 shows a flowchart of a method for generating data corresponding to the configuration file in fig. 2.
In this embodiment, the configuration file in the original text form is encoded in steps S1 to S3 as shown in fig. 2 and 3, and a binary configuration file is generated.
Specifically, in step S1, a text file of the configuration file is acquired.
In this embodiment, the configuration file is generally stored in a corresponding memory in a text form, and when performing transcoding of the configuration file, the configuration file stored in the memory is first acquired from the memory.
Furthermore, the configuration file stored in the memory may include a plurality of sets of configuration information corresponding to actual requirements of the liquid crystal display module of the MIPI interface.
In step S2, corresponding configuration data is generated from the text file.
In this embodiment, after the text file of the configuration file is acquired from the memory, when there is only one set of configuration information included in the configuration file, data corresponding to the configuration file is generated according to steps S21 to S23. When the configuration information included in the configuration file is a plurality of sets, the steps S21 to S23 are repeated a plurality of times, and the configuration data corresponding to each set of configuration information is sequentially generated. Further, the generated data includes instruction data and non-instruction data.
In step S21, the text file of the configuration file is scanned.
In this embodiment, the obtained configuration text file should be scanned integrally to ensure the correctness of the format and content of the text file. And proceeds to step S22 when the format and content of the text file are correct; when the content and format of the text file are incorrect, corresponding error prompts are generated, and the code conversion step is skipped so as to save corresponding time and processing cost.
In step S22, non-instruction information in the text file is sequentially extracted, and corresponding indexes and data are generated.
In this embodiment, the text file of the configuration file includes non-instruction information such as comments, spaces, and linefeed information, and when the format and the content of the text file are correct, the non-instruction information needs to be sequentially extracted, so as to generate corresponding indexes and data corresponding to the comments, spaces, and linefeed information in the non-instruction information, thereby effectively reducing the capacity of the configuration file.
Further, the data generated here is non-instruction data.
In step S23, the instruction information is translated item by item, and data corresponding to the configuration file is generated.
In this embodiment, the text file of the configuration file includes a plurality of instructions, and each instruction ends with a semicolon. Under the condition that the format and the content of the text file are correct, extracting and translating each instruction one by one so as to convert the text instruction needing a plurality of character descriptions into an identification code only needing one byte, and further generating data corresponding to the configuration file according to the translated instruction identification code.
Further, the data generated here is instruction data.
In a preferred embodiment, the method for encoding the MIPI profile further includes: and generating verification data according to the text file of the configuration file.
In step S3, the configuration data is binary-coded, and a configuration file in a corresponding binary format is generated.
In this embodiment, the binary encoding of the configuration data includes one of binary encoding of the configuration data, decimal encoding of the configuration data, and hexadecimal encoding of the configuration data.
Binary coding is the process of encoding characters, numbers or other objects into binary numbers by a predetermined method, or converting information and data into a predetermined binary electric pulse signal.
Further, a binary configuration file is generated when the configuration data is binary-coded, a decimal configuration file is generated when the configuration data is decimal-coded, and a hexadecimal configuration file is generated when the configuration data is hexadecimal-coded.
For convenience of description, the technical solution of the present invention will be described below by taking binary coding as an example. It is understood that when decimal encoding or hexadecimal encoding is required, the method is substantially the same as that of binary encoding.
The binary configuration file comprises at least one valid configuration area, and each valid configuration area is configured by partitioning, so that the data code of at least one instruction and the identification code of the instruction can be provided. Wherein the identification code is used for locating a corresponding instruction in an instruction fetch operation.
Referring to fig. 4, fig. 4 is a schematic diagram illustrating an encoding structure of a configuration file according to an embodiment of the present invention.
As shown in fig. 4, in this embodiment, the encoding structure of the MIPI configuration file is binary encoding, and the encoded binary configuration file includes: a head region and at least one active deployment region (including first through nth deployment regions).
The head region includes a first sub-region, a second sub-region, and a third sub-region. The first sub-area is a configuration file header area and is used for providing identification information for identifying a configuration file; the second sub-area is a file verification information area and is used for providing verification data information of a verification configuration file; the third sub-area is an MIPI configuration area information area for providing configuration information indicating the number of valid configuration areas.
The first sub-area is located at the initial position in the coded configuration file and is used for the microcontroller to identify the configuration file of the coding structure, so that correct processing can be carried out.
The second sub-area is located behind the first sub-area and stores the check code of the entire binary configuration file to provide the verification data of the configuration file. When the file is checked, the microcontroller calculates and obtains the check data of the whole configuration file before analyzing the file, and then compares whether the obtained check data is consistent with the configuration information in the second subarea, namely the file check information (check code), and only when the obtained check data is consistent with the check code, the microcontroller performs further operation. The file verification information can ensure the correctness of the configuration file.
The third sub-area is located behind the second sub-area and used for indicating the number of the configuration areas contained in the configuration file.
The configuration file of the liquid crystal display module of the general MIPI interface only needs to contain one set of configuration information, but for some liquid crystal display modules of the MIPI interface, the configuration file may contain a plurality of sets of configuration information.
In the configuration file, at least one valid configuration area is located behind the header area and is used for providing partition information of each valid configuration area, and the partition information comprises at least one of the information of the total coding length, the instruction segment length and the instruction number of the corresponding valid configuration area.
Further, each valid configuration area corresponds to one of the provisioning/storage configuration files. For example, the first valid configuration area is located behind the header area and is used for storing the first configuration information in the configuration text file in the form of a binary file; the second effective configuration area is positioned behind the first effective configuration area and used for storing second configuration information in the configuration text file in a binary file form; the n-th effective configuration area is positioned behind the n-1-th effective configuration area and used for storing the n-th configuration information in the configuration text file in the form of a binary file. Wherein n is a positive integer.
Further, the structure of each effective configuration area is the same, taking the first effective configuration area as an example, the structure includes the following areas which are sequentially set by partitions: the information processing method comprises the steps of first effective configuration area total length information, first effective configuration area instruction number information, first effective configuration area instruction length information, first effective configuration area non-instruction length information and first effective configuration area non-instruction length information.
Further, the length information is the number of bytes contained in the corresponding information in the valid allocation area.
Specifically, the total length information of the first valid configuration area is used for indicating the number of bytes contained in the first valid configuration area from the current position, so that the microcontroller can quickly locate the boundary of each valid configuration area in the configuration file.
The first valid allocation region instruction section length information is used for indicating the number of bytes contained in the first valid allocation region instruction section from the current position.
The first effective configuration area instruction segment instruction quantity information is used for indicating the instruction quantity contained in the first effective configuration area.
Preferably, each instruction ends with a semicolon in the text file of the configuration file, so that the instructions are better distinguished.
The first effective configuration area instruction segment content information, and each instruction segment content comprises an identification code, a length and data information of the instruction. For example, in the original configuration file, "mipi. lane 4" is a control instruction, which is "a 5010004" after being encoded correspondingly, wherein "A5" is an identification code, "0100" is a length, and "04" is data.
And the first effective configuration region non-instruction segment length information is used for indicating the number of bytes contained in the first configuration region non-instruction segment from the current position.
The first effective configuration area non-instruction segment content information comprises index and data information corresponding to the non-instruction information in the original configuration text file.
Further, the non-instructional information includes comments, spaces, and linefeed information in the original text file.
In this embodiment, thanks to the above encoding structure, the microcontroller can quickly locate the effective instruction portion when parsing the configuration file, and the translation of the instruction (the description of a plurality of characters is converted into a byte of identification code) enables the microcontroller to more quickly identify and execute the corresponding action, so that the efficiency is improved more significantly especially when the instruction number of the whole configuration file is large, and if a plurality of sets of configuration information exist, the switching between different configurations can also be responded faster (for example, switching between wide and narrow viewing angles).
In the following, for example, in an embodiment of the present invention, a configuration file includes two sets of configuration information, i.e., two valid configuration areas, where a first valid configuration area represents a wide view configuration and a second valid configuration area represents a narrow view configuration.
When the wide view angle configuration is carried out, the microcontroller directly reads the corresponding instruction in the first effective configuration area for operation by identifying the corresponding code in the configuration file. When a specific instruction in the wide view configuration needs to be executed, by identifying the identification code and the length code information in the instruction segment, the required instruction segment content can be directly jumped to execute the instruction, so that the response is faster.
When the narrow view configuration is required, the microcontroller can directly jump to the second effective configuration area according to the total length information of the first effective configuration area to execute the narrow view configuration. The switching between different configurations is faster, and the reading and executing efficiency of the configuration file is obviously improved.
In this embodiment, all the non-instruction data and instruction data generated in step S22 and step S23 are encoded and combined according to the encoding structure shown in fig. 2 and 3, and then an encoding-converted binary configuration file is generated.
Preferably, when the configuration file contains multiple sets of configuration information, the encoding and merging should be performed after all the data of the configuration information are ready.
Optionally, in order to avoid that the binary configuration file is intercepted by a lawbreaker so that the configuration data carried in the binary configuration file is leaked, a preset encryption algorithm may be used to encrypt the configuration data. Further, the configuration file in text form stored in the memory may be encrypted; or encrypting the configuration file during or after encoding.
Further, the preset Encryption Algorithm includes at least one of MD5 Algorithm (Message Digest Algorithm, fifth edition), DES (Data Encryption Standard, symmetric Algorithm), 3DES, RC2 (symmetric Encryption Algorithm), RC4, IDEA (International Data Encryption Algorithm), and RSA Algorithm, which is not limited in this embodiment.
In this embodiment, after the configuration file is encoded by the encoding method, a plurality of character descriptions corresponding to each instruction in the original text file are converted into an identification code of one byte, and a large number of spaces are encoded to generate an index and data with a small occupied space, thereby reducing the capacity of the configuration file to a certain extent. Meanwhile, when the configuration file is analyzed, the positioning can be faster and more accurate through the identification code information in the binary configuration file, and the identification and execution efficiency of the instructions can be obviously improved when the number of the instructions is large. In addition, the configuration file after being coded cannot be viewed and edited through a general editing text, and the confidentiality of the configuration file is increased to a certain extent.
Fig. 5 is a schematic diagram illustrating a part of a binary configuration file according to an embodiment of the present invention.
In one embodiment of the present invention, the binary configuration file may be arranged in an array as in the example shown in fig. 5, and includes a plurality of rows and a plurality of columns of binary code.
Wherein, four codes in the a area, such as "5850524D", represent the property and content of the configuration file for the configuration file header information. The microcontroller recognizes these codes to quickly and accurately find the desired binary configuration file.
The four codes in the b area, such as "DE CE 3022", are the check code information of this configuration file. Before the whole configuration file is analyzed, the codes are recognized by the microcontroller, the codes are compared with the verification data of the configuration file obtained through self calculation, and the microcontroller performs the next operation only when the comparison result is consistent.
Further, if the comparison result is inconsistent, it indicates that a certain error exists in the configuration file, and at this time, the microcontroller may send a corresponding error prompt to facilitate detection and modification by a related technician.
A code in the c-area, e.g. "02", is the configuration area information of this configuration file, which means that two valid configuration areas are included in this configuration file.
The four codes in the d area, for example, "011C 0000", are the total length information of the first valid allocation area in the two valid allocation areas of the matching file, which indicates that, starting from the current position, the first valid allocation area contains 0x1C01 bytes, i.e. the content of 0x1C01 bytes starting from the current position is the file content of the first valid allocation area.
Four codes such as "66040000" in the e area are instruction section length information of the first effective configuration area in the two effective configuration areas of the configuration file, which indicates that the instruction information section in the first effective configuration area contains 0x0466 bytes from the current position, that is, the content of 0x0466 bytes from the current position is the file content of the instruction information section in the first effective configuration area.
Two codes in the f area, for example, "4600", are the instruction information quantity information of the first effective configuration area in the two effective configuration areas of the configuration file, which indicates that the first effective configuration area contains 0x46 instructions.
The plurality of codes in the g area are the instruction segment contents of the first effective configuration area in the two effective configuration areas of the configuration file.
In the above exemplary description of the specific configuration, the code is explained by taking hexadecimal as an example, and it is understood that hexadecimal may be converted into a corresponding decimal value, for example, 0x1C01 is hexadecimal, which is equivalent to the decimal value 7169, and the same applies to the rest.
It should be noted that the binary configuration file code diagram shown in fig. 5 is only a part of the text content of the whole configuration file, and the text content related to the other information in the first effective configuration area, such as the length and content of the non-instruction segment, and the text content related to the second effective configuration area are not disclosed in fig. 5, but it is understood that the content format has a correlation with the content format already disclosed in fig. 5, and those skilled in the art can easily deduce the remaining text content according to the above detailed description.
