Abstract
Description
Technical Field
[0001] This invention relates to the field of computer technology, and in particular to a method, apparatus, device, and medium for data reverse order conversion. Background Technology
[0002] Computers store numerical values by combining basic units of information called bits, typically represented by 0 and 1. Since a single bit can only express a small amount of information, individual bits are usually linked together to form larger storage units. This smallest unit is called a byte, which consists of 8 bits and is sufficient to store a single char type of data.
[0003] In information communication, there is a phenomenon where the least significant bit (LSB) is sent first. The data received by the receiving end is stored according to the bits sent by the sending end; the receiving end receives the data exactly as the sending end sends it. If the sending end's current encoding rule is LSB-first, then the data received by the receiving end will be other data. When calculating the checksum of this data, the final checksum will be incorrect. Therefore, it is necessary to first swap the LSB and LSB of the received data to obtain the reversed data. Only then can the calculated checksum be correct.
[0004] Currently, when the encoding rule is low-order first, the byte data needs to be sorted and then reversed on the paper before the correct check value can be calculated. However, this method not only results in very low work efficiency, but also makes it difficult to process large amounts of byte data quickly and accurately.
[0005] In summary, how to quickly and accurately reverse byte data is a problem that needs to be solved. Summary of the Invention
[0006] In view of this, the purpose of this invention is to provide a data reversal conversion method, apparatus, device, and medium, capable of quickly and accurately performing reversal conversion on byte data. The specific solution is as follows:
[0007] Firstly, this application discloses a data reversal transformation method, including:
[0008] Get the target byte data sent by the data sender, and set the initial value of the reversed byte data to be obtained;
[0009] Perform a bitwise AND operation between the target byte data and 0x01 after shifting left by a first numerical bit to obtain a first operation result, and determine whether the first operation result is zero;
[0010] If it is not zero, then the reversed byte data is ORed with 0x01 after shifting left by the second numerical bit to obtain the second operation result, and the reversed byte data is updated using the second operation result;
[0011] The first value is increased by a preset unit value, and the second value is decreased by the preset unit value. Then, the process jumps back to the step of performing a bitwise AND operation between the target byte data and 0x01 shifted left by the first value, until a preset number of operations are satisfied, so as to obtain the updated reversed byte data.
[0012] Optionally, after determining whether the first operation result is zero, the method further includes:
[0013] If the result of the first operation is zero, then the first value is increased by a preset unit value, and the second value is decreased by the preset unit value, and then the process jumps back to the step of performing a bitwise AND operation between the target byte data and 0x01 shifted left by the first value.
[0014] Optionally, after obtaining the updated reversed byte data, the method further includes:
[0015] The reversed byte data is used to calculate a check value to obtain a data check value corresponding to the target byte data.
[0016] Optionally, before setting the initial value of the reversed byte data to be acquired, the method further includes:
[0017] Determine the data encoding rules used to send the target byte data;
[0018] If the data encoding rule is low-order first, then after the target byte data is obtained, the step of setting the initial value of the reverse byte data to be obtained is executed.
[0019] Optionally, after determining the data encoding rule for sending the target byte data, the method further includes:
[0020] If the data encoding rule is high-order bit first, then after obtaining the target byte data, the check value of the target byte data is calculated to obtain the corresponding data check value.
[0021] Optionally, the data reversal method further includes:
[0022] Set the preset unit value to 1.
[0023] Optionally, the data reversal method further includes:
[0024] The preset number of executions is set based on the total number of bits in the target byte data.
[0025] Secondly, this application discloses a data reversal conversion device, comprising:
[0026] The data acquisition module is used to acquire the target byte data sent by the data sender and set the initial value of the reverse byte data to be acquired.
[0027] The AND operation module is used to perform an AND operation on the target byte data and 0x01 after shifting left by a first numerical bit to obtain a first operation result, and to determine whether the first operation result is zero;
[0028] The OR operation module is used to perform an OR operation on the reversed byte data and 0x01 after left shifting by a second numerical bit if the result is not zero, so as to obtain a second operation result, and update the reversed byte data using the second operation result;
[0029] The reverse data acquisition module is used to add a preset unit value to the first value and decrease the preset unit value to the second value, and then jump back to the step of performing a bitwise AND operation between the target byte data and 0x01 after left shifting the first value, until a preset number of times is satisfied, so as to obtain the updated reverse byte data.
[0030] Thirdly, this application discloses an electronic device, including:
[0031] Memory, used to store computer programs;

[0033] Fourthly, this application discloses a computer-readable storage medium for storing a computer program; wherein, when the computer program is executed by a processor, it implements the steps of the aforementioned disclosed data reversal conversion method.
[0034] As can be seen, this application acquires the target byte data sent by the data sending end and sets the initial value of the reversed byte data to be acquired; performs a bitwise AND operation on the target byte data and 0x01 shifted left by a first numerical bit to obtain a first operation result, and determines whether the first operation result is zero; if it is not zero, performs an OR operation on the reversed byte data and 0x01 shifted left by a second numerical bit to obtain a second operation result, and updates the reversed byte data using the second operation result; increases the first value by a preset unit value, and decreases the second value by the preset unit value, and then jumps back to the step of performing a bitwise AND operation on the target byte data and 0x01 shifted left by a first numerical bit, until a preset number of times is satisfied to obtain the updated reversed byte data. Therefore, after obtaining the target byte data, this application needs to set the initial value of the reversed byte data to be obtained after reverse conversion. Then, it performs a bitwise AND operation on the target byte data and 0x01 shifted left by one numerical bit, and checks whether the first result of the AND operation is zero. If it is not zero, it performs a bitwise OR operation on the reversed byte data with the initial value and 0x01 shifted left by two numerical bits to obtain a second result, and uses the second result to update the reversed byte data. The first value is increased by a preset unit, and the second value is decreased by a preset unit, and the step of performing the bitwise AND operation on the target byte data and 0x01 shifted left by one numerical bit is repeated until the preset number of times is met, resulting in the final updated reversed byte data. This method enables fast and accurate reverse conversion of byte data sent by the data sender, improving work efficiency and saving a significant amount of time. Attached Figure Description

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0042] Currently, when the encoding rule is least significant bit first, the byte data needs to be sorted and then reversed on the manuscript paper before the correct check value can be calculated. However, this method not only results in very low work efficiency but also makes it difficult to process large amounts of byte data quickly and accurately. Therefore, this application discloses a data reversal conversion method, apparatus, device, and medium that can quickly and accurately perform byte data reversal conversion.
[0043] See Figure 1 As shown in the figure, this application discloses a data reversal conversion method, which includes:
[0044] Step S11: Obtain the target byte data sent by the data sender and set the initial value of the reverse byte data to be obtained.
[0045] In this embodiment, target byte data sent by the data sender is acquired. There can be multiple target byte data, and the target byte data is denoted as Ter. An initial value is set for each reversed byte data to be acquired, and the reversed byte data is denoted as Data. Specifically, the initial value can be set to 0, which in binary is Data = 0000 0000 = 0x00.
[0046] Step S12: Perform a bitwise AND operation between the target byte data and 0x01 after shifting left by the first numerical bit to obtain the first operation result, and determine whether the first operation result is zero.
[0047] In this embodiment, the target byte data is ANDed with 0x01 after shifting left by the first numerical bit to obtain the first operation result, and it is determined whether the first operation result is zero. It should be noted that the binary representation of 0x01 is 00000001, and the operation rule for AND is that if 0 is encountered, the result is 0. Here, the first numerical bit is denoted as i, and in the specific implementation, i starts from 0.
[0048] For example, if the target byte data is 0000 0011, then the first result of the AND operation with 0000 0001 (left-shifted by 0 bits) is 0000 0001, which means the first result is not zero; if the target byte data is 00000010, then the first result of the AND operation with 0000 0001 (left-shifted by 0 bits) is 0000 0000, which means the first result is zero.
[0049] Step S13: If it is not zero, perform an OR operation between the reversed byte data and 0x01 after shifting left by the second numerical bit to obtain the second operation result, and use the second operation result to update the reversed byte data.
[0050] In this embodiment, if the result of the first operation is not zero, the reversed byte data is ORed with 0x01 after shifting left by the second numerical bit to obtain the second operation result, and the reversed byte data is updated using the second operation result. It should be noted that the OR operation rule is that if it encounters 1, it returns 1. Here, the second numerical value is denoted as 7-i, where i starts from 0.
[0051] For example, if the current reversed byte data is Data = 0000 0000, and 0x01 is shifted left by 7 bits to get 01000000, then the result of the OR operation between 0000 0000 and 0100 0000 is 0100 0000. This result is then used to update the reversed byte data. After this update, the reversed byte data will be 0100 0000, i.e., Data = 0100 0000 = 0x40.
[0052] Step S14: Increase the first value by a preset unit value and decrease the second value by the preset unit value, then jump back to the step of performing a bitwise AND operation between the target byte data and 0x01 shifted left by the first value, until a preset number of operations are satisfied, so as to obtain the updated reversed byte data.
[0053] In this embodiment, a preset unit value is added to the first value and a preset unit value is decreased to the second value. Then, the process jumps back to the step of performing a bitwise AND operation between the target byte data and 0x01 after shifting the first value to the left. That is, if the current first value is 0 and the second value is 1, then in the second loop, the first value is 1 and the second value is 6, and so on, until the preset number of times is met, so as to obtain the final updated reversed byte data.
[0054] As can be seen, this application acquires the target byte data sent by the data sending end and sets the initial value of the reversed byte data to be acquired; performs a bitwise AND operation on the target byte data and 0x01 shifted left by a first numerical bit to obtain a first operation result, and determines whether the first operation result is zero; if it is not zero, performs an OR operation on the reversed byte data and 0x01 shifted left by a second numerical bit to obtain a second operation result, and updates the reversed byte data using the second operation result; increases the first value by a preset unit value, and decreases the second value by the preset unit value, and then jumps back to the step of performing a bitwise AND operation on the target byte data and 0x01 shifted left by a first numerical bit, until a preset number of times is satisfied to obtain the updated reversed byte data. Therefore, after obtaining the target byte data, this application needs to set the initial value of the reversed byte data to be obtained after reverse conversion. Then, it performs a bitwise AND operation on the target byte data and 0x01 shifted left by one numerical bit, and checks whether the first result of the AND operation is zero. If it is not zero, it performs a bitwise OR operation on the reversed byte data with the initial value and 0x01 shifted left by two numerical bits to obtain a second result, and uses the second result to update the reversed byte data. The first value is increased by a preset unit, and the second value is decreased by a preset unit, and the step of performing the bitwise AND operation on the target byte data and 0x01 shifted left by one numerical bit is repeated until the preset number of times is met, resulting in the final updated reversed byte data. This method enables fast and accurate reverse conversion of byte data sent by the data sender, improving work efficiency and saving a significant amount of time.
[0055] See Figure 2 As shown, this application discloses a specific data reversal method. Compared to the previous embodiment, this embodiment further explains and optimizes the technical solution. Specifically, it includes:
[0056] Step S21: Obtain the target byte data sent by the data sender and determine the data encoding rule used to send the target byte data. If the data encoding rule is low-order bit first, set the initial value of the reverse byte data to be obtained.
[0057] In this embodiment, it is necessary to determine the data encoding rule used to send the target byte data. If the data encoding rule is little-endian first, then the initial value of the reversed byte data to be acquired is set. That is, the target byte data only needs to be reversed when the data encoding rule is little-endian first.
[0058] In another specific implementation, after determining the data encoding rule for sending the target byte data, the method further includes: if the data encoding rule is high-order bit first, then after obtaining the target byte data, a checksum calculation is performed on the target byte data to obtain the corresponding data checksum. That is, if the data encoding rule is high-order bit first, the checksum calculation is performed directly on the target byte data to obtain the corresponding data checksum, without the need for reverse order processing.
[0059] Step S22: Perform a bitwise AND operation between the target byte data and 0x01 after shifting left by the first numerical bit to obtain the first operation result, and determine whether the first operation result is zero.
[0060] Step S23: If it is not zero, perform an OR operation between the reversed byte data and 0x01 after left shifting by the second numerical bit to obtain the second operation result, and use the second operation result to update the reversed byte data.
[0061] In one specific implementation, if the result of the first operation is not zero, the reversed byte data is ORed with 0x01 after shifting left by the second numerical bit, and the reversed byte data is updated using the result of the second operation obtained by the OR operation.
[0062] In another specific implementation, after determining whether the first operation result is zero, the method further includes: if the first operation result is zero, increasing the first value by a preset unit value and decreasing the second value by the preset unit value, and then jumping back to the step of performing a bitwise AND operation between the target byte data and 0x01 shifted left by a first value. That is, if the first operation result is zero, the reversed byte data obtained last time is still retained. For example, if the first operation result obtained by performing a bitwise AND operation between the target byte data and 0x01 shifted left by 0 bits is zero, then the preset unit value is directly increased to 0, the preset unit value is decreased to 7, and the method jumps back to the step of performing a bitwise AND operation between the target byte data and 0x01 shifted left by a first value, and the Data value at this time is still the initial value 0.
[0063] Step S24: Increment the first value by 1 and decrease the second value by 1, then jump back to the step of performing a bitwise AND operation between the target byte data and 0x01 shifted left by the first value, until a preset number of operations are satisfied to obtain the updated reversed byte data.
[0064] In this embodiment, the preset unit value is specifically 1, and i can specifically start from 0. So in the first loop, the first value is 0 and the second value is 7; in the second loop, the first value is 1 and the second value is 6; in the third loop, the first value is 2 and the second value is 5, and so on, until the preset number of times is met, the loop ends and the final reversed byte data is obtained.
[0065] Furthermore, the above method also includes setting the preset execution count based on the total number of bits in the target byte data. It can be understood that if the total number of bits in the target byte data is 8, then the preset execution count can be set to 8, meaning it needs to loop 8 times.
[0066] Step S25: Calculate the check value of the reversed byte data to obtain the data check value corresponding to the target byte data.
[0067] In this embodiment, the obtained reversed byte data is used to calculate the check value to obtain the data check value corresponding to the target byte data. That is, through the above scheme, when the data encoding rule is set to low bit first, the target byte data can be reversed to obtain the correct data check value.
[0068] For a more detailed description of the process of step S22, please refer to the relevant content disclosed in the foregoing embodiments, which will not be repeated here.
[0069] As can be seen, in this embodiment of the application, when the current data encoding rule is determined to be little-endian first, after obtaining the target byte data sent by the data sender, it is necessary to perform reverse order conversion to obtain its reversed byte data. Then, a check value is calculated on the reversed byte data to obtain the data check value corresponding to the target byte data. Through the eight loops in the above scheme, the byte data sent by the data sender can be reversed quickly and accurately, thereby improving work efficiency. If the data encoding rule is big-endian first, there is no need to perform reverse order conversion; the data check value can be calculated directly.
[0070] See Figure 3 As shown, the technical solution in this application will be described in detail below, taking the target byte data transmitted by the data sender as 0x3A, i.e., 00111010:
[0071] First, obtain the target byte data Ter = 0x3A = 0011 1010, and set the initial value of the reversed byte data Data = 0x00 = 0000 0000; the first value is denoted as i, and the second value is denoted as 7-i;
[0072] In the first loop, i = 0. Then, 0x3A is ANDed with 0x01 after shifting left by 0 bits to get the first result, i.e., 0x3A&(0x01<<0=0x01)=0x00. In other words, the first result is 0. Therefore, the Data value remains 0x00. Then, i = 0 is incremented by 1 to get i = 1.
[0073] In the second loop, i = 1. Then, the first result is obtained by performing a bitwise AND operation between 0x3A and 0x01 (shifted left by 1 bit), i.e., 0x3A & (0x01 << 1 = 0x02) = 0x02. The first result is not 0. Then, the second result is obtained by performing a bitwise OR operation between the reversed byte data Data = 0x00 and 0x01 (shifted left by 6 bits), i.e., Data | = (0x01 << (7-1)) = 0x40 = 0100 0000. Data has been updated to the second result after the bitwise OR operation. Then, i = 1 is incremented by 1 to get i = 2. 7 - i = 6 is decremented by 1 to get 7 - i = 5.
[0074] In the third loop, i = 2. Then, the AND operation between 0x3A and 0x01 (left-shifted by 2 bits) is performed to obtain the first result, i.e., 0x3A & (0x01 << 2 = 0x04) = 0x00. That is, the first result is 0. The Data value remains the result of the second loop, i.e., Data = 0x40 = 0100 0000. Then, i = 2 is incremented by 1 to get i = 3. 7 - i = 5 is decremented by 1 to get 7 - i = 4.
[0075] In the 4th loop, i = 3. Then, the first result is obtained by performing a bitwise AND operation between 0x3A and 0x01 (shifted 3 bits to the left): 0x3A & (0x01 << 3 = 0x08) = 0x08. The first result is not 0. The second result is obtained by performing a bitwise OR operation between the reversed byte data Data = 0x40 and 0x01 (shifted 4 bits to the left): Data | = (0x01 << (7-3)) = 0x50 = 0101 0000. Data has been updated to the second result after the bitwise OR operation. Then, 1 is added to i = 3 to get i = 4. 1 is subtracted from 7 - i = 4 to get 7 - i = 3.
[0076] In the 5th loop, i = 4. Then, the first result is obtained by performing a bitwise AND operation between 0x3A and 0x01 (shifted 4 bits to the left): 0x3A & (0x01 << 4 = 0x10) = 0x10. The first result is not 0. The second result is obtained by performing a bitwise OR operation between the reversed byte data Data = 0x50 and 0x01 (shifted 3 bits to the left): Data | = (0x01 << (7-4)) = 0x58 = 0101 1000. Data has been updated to the second result after the bitwise OR operation. Then, i = 4 is incremented by 1 to get i = 5. 7 - i = 3 is decremented by 1 to get 7 - i = 2.
[0077] In the 6th loop, i = 5. Then, the first result is obtained by performing a bitwise AND operation between 0x3A and 0x01 (shifted 5 bits to the left): 0x3A & (0x01 << 5 = 0x20) = 0x20. The first result is not 0. The second result is obtained by performing a bitwise OR operation between the reversed byte data Data = 0x58 and 0x01 (shifted 2 bits to the left): Data| = (0x01 << (7-5)) = 0x5C = 0101 1100. Data has been updated to the second result after the bitwise OR operation. Then, i = 5 is incremented by 1 to get i = 6, and 7 - i = 2 is decremented by 1 to get 7 - i = 1.
[0078] In the 7th loop, i = 6. Then, the AND operation between 0x3A and 0x01 (left-shifted by 6 bits) is performed to obtain the first result, i.e., 0x3A&(0x01<<6=0x40)=0x00, which means the first result is 0. The Data value remains the result of the 6th loop, i.e., Data=0x5C=0101 1100. Then, i=6 is incremented by 1 to get i=7. Then, 7-i=1 is decremented by 1 to get 7-i=0.
[0079] In the 8th loop, i = 7. Then, the first result is obtained by performing a bitwise AND operation between 0x3A and 0x01 (shifted 7 bits to the left): 0x3A & (0x01 << 7 = 0x80) = 0x00. This means that the first result is 0. Therefore, the Data value remains the result from the 6th loop: Data = 0x5C = 0101 1100.
[0080] Therefore, after 8 iterations, the reversed byte data Data = 0101 1100, corresponding to the target byte data Ter = 0011 1010, is obtained, thus achieving the reverse byte data conversion. Furthermore, the change in the Data value in each iteration shows that the value of the lower bits of Ter is synchronized starting from the high-order bits of Data.
[0081] See Figure 4As shown in the figure, this application discloses a data reversal conversion device, which includes:
[0082] The data acquisition module 11 is used to acquire the target byte data sent by the data sender and set the initial value of the reverse byte data to be acquired;
[0083] AND operation module 12 is used to perform an AND operation on the target byte data and 0x01 after shifting left by a first numerical bit to obtain a first operation result, and to determine whether the first operation result is zero;
[0084] OR operation module 13 is used to perform an OR operation on the reversed byte data and 0x01 after left shifting by a second numerical bit if the result is not zero, so as to obtain a second operation result, and update the reversed byte data using the second operation result;
[0085] The reverse data acquisition module 14 is used to add a preset unit value to the first value and decrease the preset unit value to the second value, and then jump back to the step of performing a bitwise AND operation between the target byte data and 0x01 after left shifting the first value, until a preset number of times is satisfied, so as to obtain the updated reverse byte data.
[0086] As can be seen, this application acquires the target byte data sent by the data sending end and sets the initial value of the reversed byte data to be acquired; performs a bitwise AND operation on the target byte data and 0x01 shifted left by a first numerical bit to obtain a first operation result, and determines whether the first operation result is zero; if it is not zero, performs an OR operation on the reversed byte data and 0x01 shifted left by a second numerical bit to obtain a second operation result, and updates the reversed byte data using the second operation result; increases the first value by a preset unit value, and decreases the second value by the preset unit value, and then jumps back to the step of performing a bitwise AND operation on the target byte data and 0x01 shifted left by a first numerical bit, until a preset number of times is satisfied to obtain the updated reversed byte data. Therefore, after obtaining the target byte data, this application needs to set the initial value of the reversed byte data to be obtained after reverse conversion. Then, it performs a bitwise AND operation on the target byte data and 0x01 shifted left by one numerical bit, and checks whether the first result of the AND operation is zero. If it is not zero, it performs a bitwise OR operation on the reversed byte data with the initial value and 0x01 shifted left by two numerical bits to obtain a second result, and uses the second result to update the reversed byte data. The first value is increased by a preset unit, and the second value is decreased by a preset unit, and the step of performing the bitwise AND operation on the target byte data and 0x01 shifted left by one numerical bit is repeated until the preset number of times is met, resulting in the final updated reversed byte data. This method enables fast and accurate reverse conversion of byte data sent by the data sender, improving work efficiency and saving a significant amount of time.
