The second instruction is obtained by carrying out first processing on the first instruction, so that the working power consumption of the electronic equipment when the electronic equipment adopts the instruction meeting the first condition is reduced, meanwhile, the second instruction and a third instruction screened according to the second condition are subjected to second processing according to a specific algorithm, and finally a compression instruction mode is formed, so that one compression instruction actually comprises two instructions, the space occupied by the instructions can be greatly saved, and the processing efficiency or the storage capacity of the electronic equipment capable of using or storing the compression instruction is improved.
In order to understand the above technical solutions more simply and in detail, the following describes the above image processing method in detail with reference to the embodiments and the drawings.
As shown in fig. 1 and fig. 2, fig. 1 is a flowchart of an instruction processing method provided in an embodiment of the present application, where the instruction processing method specifically includes the following steps:
step 101: and screening a first instruction from the instruction set according to a first condition, wherein the electronic equipment has first working power consumption when running by adopting the first instruction. As an example, taking the instruction of the computer processor as an example, the instruction in the computer processor is a character string composed of a first character and/or a second character, that is, may be a character string including a character 1 and a character 0, where the character 1 is at a high level, i.e., the more characters 1 are included in the instruction of the computer processor, the higher the operating power consumption of the electronic device when the instruction is stored or transmitted. Because the number of instructions in the instruction set used in the electronic device is large, when the first instruction is screened according to the first condition, on one hand, the first condition may be that an instruction with a higher frequency of use is selected from the instruction set as the first instruction; on the other hand, the first condition may be to select a partial instruction as the first instruction based on the arrangement of the first character and the second character in the instruction, such as to select an instruction having three characters "1" between two characters "0" (the number of characters "1" is greater than that of characters "0") from the instruction as the first instruction, such as the first instruction may be "11011101", "10111011", "11100111", or "01110111".
Step 102: and performing first processing on the first instruction to obtain a second instruction, wherein the electronic equipment has second working power consumption when the electronic equipment adopts the second instruction to run, and the second working power consumption is lower than the first working power consumption. Wherein the first instruction and the second instruction may each be composed of a character string including a plurality of characters, such as "11100111" as the first instruction, as an example.
In one embodiment, in order to reduce the number of instructions and reduce the number of characters "1" in the frequently executed first instruction and finally form a compressed instruction under the condition that it is ensured that the first instruction can be restored and executed, after the first instruction is subjected to the first processing, the number of characters "1" in the formed compressed instruction is reduced, so that the operating power consumption of the electronic device is reduced, for example, in the process of storing or transmitting the instruction, the power consumption can be reduced because the number of characters "1" representing high levels is small. The first processing the first instruction comprises: and performing negation processing on the characters of the first instruction, wherein the negation processing represents that a first character in the characters of the first instruction is replaced by a second character, and the second character in the first instruction is replaced by the first character. Specifically, as an example, the negation processing may be performed on "11100111", where the negation processing represents that the character "1" is replaced by "0", and simultaneously, the character "0" is replaced by "1", so as to obtain the second instruction "00011000", and it can be seen that the number of the character "1" with the high level in "11100111" of the first instruction is 6, and the number of the character "1" with the high level in the second instruction "00011000" is only 2, that is, the second operating power consumption of the electronic device when the electronic device operates by using the second instruction is smaller than the first operating power consumption of the electronic device when the electronic device operates by using the first instruction.
Step 103: and screening third instructions from the instruction set according to a second condition, screening all or part of the second instructions from all the second instructions according to the second condition, and carrying out second processing on the selected second instructions and the corresponding third instructions according to a specific algorithm to form compressed instructions.
Since the second instruction and the third instruction are processed to obtain the compressed instruction, the number of instructions is actually reduced, that is, two original instructions are converted into one instruction, so that precious storage space (such as limited storage space in a register or a cache) can be saved in the process of storing the instructions.
In some embodiments of the application, the second instruction and the third instruction are both composed of a first character and a second character, and the number of the first character is contained in the instruction, so that when the instruction is used by the electronic device, the electronic device has positive correlation with the work power consumption.
As shown in fig. 2, the screening of the third instruction from the instruction set according to the second condition, and screening all or part of the second instructions from all the second instructions according to the second condition includes:
s1031, selecting the number of the two first characters not exceeding a specific numerical value according to the second condition, wherein the uneven same bit is a to-be-selected instruction of the first characters;
and S1032, judging the number of the first characters in each instruction to be selected, determining the instruction with more first characters as a selected second instruction, and determining the instruction with less first characters as a third instruction corresponding to the selected second instruction.
Specifically, when the second instruction and the third instruction are filtered, a plurality of instructions composed of the first character (1) and the second character (0) are taken as an example, for example, an instruction composed of 8 "1" and/or "0" is taken as an example, and the third instruction and all or part of the second instruction are filtered, so that the following preconditions need to be met: the number of the first characters is selected not to exceed a specific value (e.g., not to exceed three), and the parity bits of the second instruction and the third instruction are not uniform for the first character. Specifically, when the instruction is composed of 8 "1" s and/or "0" s, the number of "1" s in the screened second instruction and the corresponding third instruction cannot exceed three, and the character "1" cannot appear simultaneously in the same bit among 8 bits of the second instruction and the third instruction. Under the precondition, the second instruction and the third instruction are screened according to the following screening rule one: looking at the number of the first characters, determining the instruction with more first characters as a second instruction (e.g. 11000010), and determining the instruction with less first characters as a third instruction (which needs to meet the above-mentioned preconditions) corresponding to the second instruction (e.g. 0001100; when the number of the first characters is the same, the instruction with the first character closest to the left side of the whole character string is selected as the second instruction (e.g., 11000000), and the instruction with the first character farther from the left side of the whole character string is selected as the third instruction (which is required to meet the above-mentioned precondition) corresponding to the second instruction, e.g., 0001100.
In addition, the second instruction and the third instruction may be screened according to the following screening rule two under the above premise: if the following situation occurs, when one instruction is divided into two parts according to the number of characters, the first part is four characters (including the first character and/or the second character), and the second part is four second characters, the instruction is determined as the second instruction, correspondingly, when another instruction is divided into two parts according to the number of characters, the first part is four second characters, and the second part is four characters (including the first character and/or the second character), the instruction is determined as the third instruction corresponding to the second instruction. Still taking the example of an instruction consisting of 8 "1" s and/or "0" s, such as the instruction 10100000, whose last four bits are "0", is screened as the second instruction, and correspondingly, if 00000111 is encountered, whose first four bits are "0", is screened as the third instruction corresponding to the second instruction.
Furthermore, in order to increase the success rate of the operation of the compressed instruction, the identities of the selected second instruction and the selected third instruction may be removed if the two instructions are screened as the second instruction and the third instruction, respectively, and after the second instruction and the third instruction are compressed (for example, an addition operation), the compressed instruction is formed, but the compressed instruction cannot be accurately restored to the original second instruction and the original third instruction, so that the two instructions are not compressed any more.
In some embodiments of the application, said second processing said second instruction and said third instruction according to a specific algorithm to form a compressed instruction, as shown in fig. 3, comprises the following steps:
s1033, matching the characters at the corresponding positions in the second instruction and the third instruction with each other, and adding identification characters;
s1034, forming a compression instruction based on the matched characters and the identification characters.
The identification character is used for identifying the compression mode of the two instructions and the third instruction, so that the second instruction and the third instruction are restored when the compression instruction is executed or called, and the identification character can comprise at least two characters.
For example, assuming that the first instruction is "11100111", the second instruction is "00011000", accordingly, the third instruction is "11000001", and in this case, the compressed instruction is "11011001", and the flag character is added before or after "11011011001", and in this case, if the flag is added before the compressed instruction, and if the flag is added after the compressed instruction, that is, the addition method is set to be uniform, and in this embodiment, the second instruction "00011000" and the third instruction "11000001" are compressed and then "11011001". In one embodiment, adding the identification to the compressed instruction may be: adding a mark "10" or "11" at the end of the instruction, wherein the first character is "1", which indicates that the instruction with the character "1" corresponding to the position between the at least two non-adjacent second characters (which may be character 0) in the restored instruction is preceded by "00011000", and the instruction with the character "0" corresponding to the position between the at least two non-adjacent second characters (which includes two instructions arranged in a tandem order) in the restored instruction is followed by "11000001"; and the second character "0" indicates that the preceding instruction "00011000" is the second instruction, i.e., the instruction resulting from the first processing (inverting) of the first instruction, and if the second character is "1", the second character "1" indicates that the following instruction is the second instruction. Of course, the way of adding the identifier after the compression instruction and the corresponding definition can also be set according to the actual needs of the user, so as to guide the specific reduction operation, thereby better meeting the requirements of the user.
In some embodiments of the application, the compress instruction is to execute or invoke, wherein the executing or invoking of the compress instruction comprises: reading the compression instruction to obtain the identification character of the compression instruction and the character matched with the identification character; and processing the characters matched with each other based on the identification characters, and restoring to obtain the first instruction and the third instruction. Specifically, after the characters matched with each other are processed, the second instruction and the third instruction may be obtained first, and then the first instruction is obtained based on the second instruction. For example, after the second instruction "00011000" and the third instruction "11000001" are compressed, they are "1101100110", that is, the identification character is "10", and if the identification is performed in an identification manner, the restored instructions are "00011000" and "11000001" based on the first identification character being "1", and the second identification character being "0", the second instruction is "00011000", and the third instruction is "11000001".
Further, in some embodiments of the application, the processing the mutually matched characters based on the identification character, and restoring to obtain the first instruction and the third instruction include: analyzing the characters matched with each other based on the identification characters to obtain characters in the second instruction and characters in the third instruction; analyzing characters in the second instruction based on the identification characters to obtain characters of the first instruction; and obtaining the first instruction and the third instruction based on the character of the first instruction and the character of the third instruction. For example, the second instruction "00011000" and the third instruction "11000001" are compressed and then become "1101100110", wherein the identification character is "10", and in an example of identification by adding identification means, the restored instructions are "00011000" and "11000001" based on the first identification character being "1", the second instruction is "00011000" based on the second identification character being "0", the third instruction is "11000001", and the second instruction is inverted to obtain the first instruction "11100111".
The embodiment of the present invention further provides an electronic device, as shown in fig. 4, including:
the electronic equipment comprises a first processing module and a second processing module, wherein the first processing module is configured to filter a first instruction from an instruction set according to a first condition, and the electronic equipment has first working power consumption when running by adopting the first instruction. As an example, the instruction of the computer processor is a character string composed of a first character and/or a second character, that is, it may be a character string including a character 1 and a character 0, where the character 1 is at a high level, that is, the more characters 1 are included in the instruction of the computer processor, the higher the operating power consumption of the electronic device when the instruction is stored or transmitted. Because the number of instructions in the instruction set used in the electronic device is large, when the first processing module filters the first instruction according to the first condition, on one hand, the first condition may be that an instruction with a higher use frequency is selected from the instruction set and used as the first instruction; on the other hand, the first condition may be to select a partial instruction as the first instruction based on the arrangement of the first character and the second character in the instruction, such as to select an instruction having three characters "1" between two characters "0" (the number of characters "1" is greater than that of characters "0") from the instruction as the first instruction, such as the first instruction may be "11011101", "10111011", "11100111", or "01110111".
The second processing module is configured to perform first processing on the first instruction to obtain a second instruction, and the electronic device has second working power consumption when running by using the second instruction, wherein the second working power consumption is lower than the first working power consumption. Wherein the first instruction and the second instruction may each be composed of a character string including a plurality of characters, such as "11100111" as the first instruction, as an example.
In an embodiment, in order to reduce the number of instructions and reduce the number of characters "1" in the frequently executed first instruction to finally form a compressed instruction under the condition that it is ensured that the first instruction can be restored and executed, after the second processing module performs the first processing on the first instruction, the number of characters "1" in the formed compressed instruction is reduced, thereby reducing the operating power consumption of the electronic device, for example, in the process of storing or transmitting the instruction, the power consumption can be reduced because the number of characters "1" representing high levels is small. The first processing the first instruction comprises: and performing negation processing on the characters of the first instruction, wherein the negation processing represents that a first character in the characters of the first instruction is replaced by a second character, and the second character in the first instruction is replaced by the first character. Specifically, as an example, the negation processing may be performed on "11100111", where the negation processing represents that the character "1" is replaced by "0", and simultaneously, the character "0" is replaced by "1", so as to obtain the second instruction "00011000", and it can be seen that the number of the character "1" with the high level in "11100111" of the first instruction is 6, and the number of the character "1" with the high level in the second instruction "00011000" is only 2, that is, the second operating power consumption of the electronic device when the electronic device operates by using the second instruction is smaller than the first operating power consumption of the electronic device when the electronic device operates by using the first instruction.
And the compression module is configured to screen a third instruction from the instruction set according to a second condition, screen all or part of second instructions from all second instructions according to the second condition, and perform second processing on the selected second instruction and the third instruction according to a specific algorithm to form a compressed instruction. Since the second instruction and the third instruction are processed to obtain the compressed instruction, the number of instructions is actually reduced, that is, two original instructions are converted into one instruction, so that precious storage space (such as limited storage space in a register or a cache) can be saved in the process of storing the instructions.
In some embodiments of the application, the second instruction and the third instruction are both composed of a first character and a second character, and the number of the first character is contained in the instruction, so that when the instruction is used by the electronic device, the electronic device has positive correlation with the work power consumption.
The compression module is further configured to:
selecting two first characters according to the second condition, wherein the number of the two first characters does not exceed a specific numerical value, and the two first characters are not uniform in identical bits and are to-be-selected instructions of the first characters;
and judging the number of the first characters in each instruction to be selected, determining the instruction with more first characters as a selected second instruction, and determining the instruction with less first characters as a third instruction corresponding to the selected second instruction.
Specifically, when the second instruction and the third instruction are filtered, taking a plurality of instructions composed of the first character (1) and the second character (0) as an example, for example, the instructions composed of 8 "1" and/or "0" are used as an example, the compression module filters the third instruction and all or part of the second instruction, and the following preconditions need to be met: the number of the first characters is selected not to exceed a specific value (e.g., not to exceed three), and the parity bits of the second instruction and the third instruction are not uniform for the first character. Specifically, when the instruction is composed of 8 "1" s and/or "0" s, the number of "1" s in the screened second instruction and the corresponding third instruction cannot exceed three, and the character "1" cannot appear simultaneously in the same bit among 8 bits of the second instruction and the third instruction. Under the precondition, the second instruction and the third instruction are screened according to the following screening rule one: looking at the number of the first characters, determining the instruction with more first characters as a second instruction (e.g. 11000010), and determining the instruction with less first characters as a third instruction (which needs to meet the above-mentioned preconditions) corresponding to the second instruction (e.g. 0001100; when the number of the first characters is the same, the instruction with the first character closest to the left side of the whole character string is selected as the second instruction (e.g., 11000000), and the instruction with the first character farther from the left side of the whole character string is selected as the third instruction (which is required to meet the above-mentioned precondition) corresponding to the second instruction, e.g., 0001100.
In addition, the compression module may also screen out the second instruction and the third instruction according to the following screening rule two on the premise: if the following situation occurs, when one instruction is divided into two parts according to the number of characters, the first part is four characters (including the first character and/or the second character), and the second part is four second characters, the instruction is determined as the second instruction, correspondingly, when another instruction is divided into two parts according to the number of characters, the first part is four second characters, and the second part is four characters (including the first character and/or the second character), the instruction is determined as the third instruction corresponding to the second instruction. Still taking the example of an instruction consisting of 8 "1" s and/or "0" s, such as the instruction 10100000, whose last four bits are "0", is screened as the second instruction, and correspondingly, if 00000111 is encountered, whose first four bits are "0", is screened as the third instruction corresponding to the second instruction.
Furthermore, in order to increase the success rate of the operation of the compressed instruction, the identities of the selected second instruction and the selected third instruction may be removed if the two instructions are screened as the second instruction and the third instruction, respectively, and after the second instruction and the third instruction are compressed (for example, an addition operation), the compressed instruction is formed, but the compressed instruction cannot be accurately restored to the original second instruction and the original third instruction, so that the two instructions are not compressed any more.
In some embodiments of the application, the compression module is further configured to: matching characters at corresponding positions in the second instruction and the third instruction with each other, and adding identification characters; and forming a compression instruction based on the matched characters and the identification characters.
The identification character is used for identifying the compression mode of the two instructions and the third instruction, so that the second instruction and the third instruction are restored when the compression instruction is executed or called, and the identification character can comprise at least two characters.
For example, assuming that the first instruction is "11100111", the second instruction is "00011000", accordingly, the third instruction is "11000001", and in this case, the compressed instruction is "11011001", and the flag character is added before or after "11011011001", and in this case, if the flag is added before the compressed instruction, and if the flag is added after the compressed instruction, that is, the addition method is set to be uniform, and in this embodiment, the second instruction "00011000" and the third instruction "11000001" are compressed and then "11011001". In one embodiment, adding the identification to the compressed instruction may be: adding a mark "10" or "11" at the end of the instruction, wherein the first character is "1", which indicates that the instruction with the character "1" corresponding to the position between the at least two non-adjacent second characters (which may be character 0) in the restored instruction is preceded by "00011000", and the instruction with the character "0" corresponding to the position between the at least two non-adjacent second characters (which includes two instructions arranged in a tandem order) in the restored instruction is followed by "11000001"; while the second character "0" indicates that the preceding instruction "00011000" is the second instruction, i.e., the instruction resulting from the negation, and if the second character is "1" the second character "1" indicates that the following instruction is the second instruction. Of course, the way of adding the identifier after the compression instruction and the corresponding definition can also be set according to the actual needs of the user, so as to guide the specific reduction operation, thereby better meeting the requirements of the user.
In some embodiments of the application, the electronic device further comprises a restore module configured to:
reading the compression instruction to obtain the identification character of the compression instruction and the character matched with the identification character;
and processing the characters matched with each other based on the identification characters, and restoring to obtain the first instruction and the third instruction.
Specifically, after the characters matched with each other are processed, the second instruction and the third instruction may be obtained first, and then the first instruction is obtained based on the second instruction. For example, after the second instruction "00011000" and the third instruction "11000001" are compressed, they are "1101100110", that is, the identification character is "10", if the identification is performed in an identification manner, if the first identification character is "1", the restored instructions are "00011000" and "11000001", and if the second identification character is "0", the second instruction is "00011000", and the third instruction is "11000001".
