Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for compressing specific data by a mobile terminal according to a preferred embodiment of the present invention.
As shown in fig. 1, a method for compressing specific data by a mobile terminal according to an embodiment of the present invention includes the following steps:
step S100, the mobile terminal obtains data to be processed, converts the data to be processed into hexadecimal data and then represents the converted data, and judges whether each bit in the obtained hexadecimal data is less than ten, if so, the data to be processed is judged to be specific data.
In the invention, the format of the data to be processed is a sequence consisting of 0 and 1, when the mobile terminal converts the data P to be processed into hexadecimal data P1 by hexadecimal, if each bit in the obtained hexadecimal data P1 is less than ten, the data P to be processed is specific data; after the mobile terminal converts the data P to be processed into hexadecimal data P1, if at least one bit of the obtained hexadecimal data P1 is greater than or equal to ten, the data P to be processed is not specific data, and the next processing is not performed.
Specifically, for example, the data to be processed is 00010010010010000011 (P), each four bits of the data are represented by hexadecimal to obtain 12483 (P1), and it is determined that each bit 1\2\4\8\3 is less than ten, so that the data to be processed is specific data; for another example, the data to be processed is 00010010010010001111 (P), the four bits of the data are represented by hexadecimal to obtain 1248F (P1), and (F) represents fifteen in hexadecimal, wherein each bit 1\2\4\8 is less than ten, but the lowest bit F is greater than 10, so the data to be processed is not specific data.
And step S200, representing the specific data in a hexadecimal reverse order to obtain the hexadecimal reverse order data, namely, sequentially reversing the hexadecimal data from the last bit to the first bit to represent the hexadecimal data.
In the invention, the specific data P, namely P1 is represented as C1C 2C3 … … CX in a hexadecimal reverse order and is represented as P2, wherein CX represents a one-bit hexadecimal number in the specific data, the larger X is, the higher X is, the X takes the value of 1, 2, 3, … … N, and N is a natural number; the C1C 2C3 … … CX is expressed by sequentially reversing the hexadecimal data P1 from the last bit to the first bit.
Specifically, as described above, the specific data 12483 (P1) such as a hexadecimal representation, and thus C1=3, C2=8, C3=4, C4=2, C5=1, is represented as 38421 (P2) in the reverse order of hexadecimal in step S200.
And step S300, converting the hexadecimal inverted sequence data into decimal data in a decimal mode.
In the invention, the formula for converting the hexadecimal reverse order data P2 into decimal data P3 by decimal is as follows: p3= C1 × 100+C2*101+C3*102+ ……CX*10X-1(ii) a And the hexadecimal reverse-order data P2 is subjected to a decimal conversion formula to obtain decimal data P3.
In particular, as described above, for example according to P3= C1 x 100+C2*101+C3*102+ ……CX*10X-1To obtain decimal data P3, which, for the specific data 12483 (P1) in hexadecimal representation, results in C1=3, C2=8, C3=4, C4=2, C5=1 in step S200, then for the specific data, the decimal data P3 is calculated as follows:
P3= C1*100+C2*101+C3*102+ ……CX* 10X-1
=3*100+8*101+4*102+2*103+1*104
=12483
and step S400, converting the decimal data into binary data in a binary mode, and storing the binary data into a memory.
In the invention, binary data P4 is obtained by binary conversion of the decimal data P3;
the mobile terminal stores the binary data P4 in the memory to complete the compression of the specific data.
Specifically, as described above, for example, the decimal data P3 is converted into binary 11000011000011 and stored in the memory. Therefore, in summary from step S100 to step S400, the data 00010010010010000011 (P, binary representation) to be processed is finally converted into 11000011000011 (P4, binary representation) and stored in the memory, and the compression process for the specific data is completed.
The method of the invention expresses the specific data in the reverse order of hexadecimal, converts the specific data into decimal number to obtain data P3, and finally converts the number P3 into binary number to be stored in a memory; therefore, the method for compressing the data is further improved to improve the utilization rate of the memory, so that the mobile terminal can store more data.
