Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The data processing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, fig. 1 is a flowchart of a data processing method provided in an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
In the embodiment of the present application, the pre-stored first data codes may be binary data codes, and may also be octal, decimal, or hexadecimal codes, and are used to generate periodic pseudo-random sequences. The first data code may be stored in a register or other storage medium in advance, or the first data code may be output from a register. The Register may be a Linear Feedback Shift Register (LFSR).
And 102, generating a periodic pseudo-random sequence according to the first data code.
In the step 102, the pseudo-random sequence corresponds to an encryption key in data encryption, and in the embodiment of the present application, in order to ensure the length of the pseudo-random sequence, the pseudo-random sequence may be generated by the first data encoding, and thus is a periodic cyclic encoding sequence.
In this embodiment of the present application, in order to eliminate the periodic code in the second data code to be transmitted, the code length of one period of the pseudo-random sequence needs to be set according to actual needs. In general, assuming that the period of the second data code to be transmitted in which the same code occurs in the same bit is 10 bits, it is necessary to avoid that the code length of one period of the pseudo random sequence is 10 bits or less than 10 bits, so as to prevent the periodic code in the second data code from being unable to be eliminated. Optionally, the code length of one period of the pseudo random sequence may be an integer multiple of 2, 3, or 4 of the period of the second data codes in which the same codes occur at the same bit.
Specifically, the pseudo-random sequence may be generated by an LFSR module, and the LFSR module may serve as a pseudo-random code generator. An n-stage LFSR is composed of n flip-flops and several exclusive-OR gates, and can generate a period of 2 according to defined initial state and sequential logicn-1.
N elements are always stored in the LFSR module, and are called a state, and the state at the initial time is S1＝(b1,b2,……,bn) (ii) a The state at the ith time is Si＝(bi,bi+1,……,bi+n-1). Wherein i is an integer of 1 to n.
For the LFSR module, the state code at the initial time may be regarded as the first data code, and the sequential logic may be a characteristic polynomial determined by the LFSR structure. For example, when the LFSR of n-step generates the sequence b according to the initial stateiWith a period T of 2n-1When it is called { biIs an n-th order sequence. If LFSR sequence { biSatisfy bn+1＝t1b1+t2b2+…+tnbnLet p (x) be 1-t1x1+t2x2+……+tnxn(t0P (x) is called as LFSR characteristic polynomial. Wherein, t1～tnCoefficients representing a linear characteristic polynomial.
Upon completion of step 102 by the LFSR module, the pseudo-random sequence corresponds to a periodic sequence generated by a characteristic polynomial.
And 103, encrypting the second data code to be sent according to the pseudo-random sequence to obtain a third data code.
In step 103, the second data code to be transmitted may be image data transmitted through an MIPI interface, and specifically may be in the form of 8bit, 10bit, 12bit, or 16 bit.
In an embodiment of the present application, if the second data code is 10-bit format and there is a specific code in some bits of each data in the second data code, the second data code may be XXXXXX0110 xxxxxxxx 0110. It can be seen that the code 0110 appears periodically every 10 bits in the second data code.
The third data code is obtained based on the second data code, and may be implemented by a logical operation between the second data code and the pseudo random sequence. For example, the process of encrypting the second data code by using the LFSR module is a process of bitwise xoring the second data code and the pseudo random sequence. After the second data codes are encrypted, the obtained third data codes are pseudo-random codes, so that the periodic codes in the second data codes are eliminated through encryption processing.
It should be noted that, since the number of bits of the second data code may be different from that of the pseudorandom sequence, in the encryption process, it is only necessary to encrypt all codes in the second data code, that is, to consider the encryption as being completed.
In addition, in the embodiment of the present application, a plurality of pseudo random sequences may be generated, and the second data encoding may be encrypted for a plurality of times, so as to ensure that the periodic encoding in the second data encoding is eliminated.
And 104, obtaining mobile industry processor MIPI data codes based on the third data codes.
In the embodiment of the present application, the second data code to be transmitted may be an image data code, and the image data code includes formats such as 8bit, 10bit, 12bit, or 16 bit. In order to enable the image data to be transmitted through the MIPI interface, the third data codes outside the 8-bit format need to be recombined and coded, and finally, the MIPI data codes with the 8-bit format are obtained.
In the embodiment of the application, the second data code to be sent is encrypted according to the generated pseudo-random sequence to obtain a third data code, so that the periodic code in the second data code to be sent can be eliminated; and then, MIPI data codes are obtained based on the third data codes, so that periodic codes in the MIPI data codes are eliminated, spectrum spikes generated in the data transmission process of the MIPI interface are eliminated, and communication interference in the data processing transmission process through the MIPI interface is reduced.
Optionally, the first data code is an N-bit binary code, and at least one bit code is 1; n is a positive integer greater than 1.
In this embodiment, since the first data code is used to generate a pseudo-random sequence, and the pseudo-random sequence can perform a logic operation with a second data code to be transmitted, the first data code can correspond to the second data code and be an N-bit binary code.
Meanwhile, considering that in the process of generating the pseudo random sequence by using the linear feedback shift register, when the first data codes are all 0, the register is in a disabled state, and therefore at least one bit of the first data codes is 1.
Further, the step 102 may specifically include:
generating a period of 2 according to the N-bit binary codeN-1.
In step 102, the period of the pseudo random sequence corresponds to the number of bits of the first data code, and if the number of binary code bits of the first data code is N, 2 can be generated in addition to all 0 codesN-1 stateThe sequence of each state of the pseudo-random sequence may be determined by sequential logic of a register, and the period of the specific sequence is 2NThe pseudo-random sequence of-1 is the above pseudo-random sequence.
It is to be understood that, in order to eliminate the periodicity coding in the second data code to be transmitted, and avoid that the periodicity of the second data code is not completely eliminated due to too few bits of the pseudo random sequence, the bit number N of the binary code may be defined as a larger value. In this embodiment, the number N of bits of the binary code may be greater than or equal to the unit number of bits of the second data code, that is, if the second data code is in a 10-bit format, N may be an integer greater than or equal to 10.
Further, the step 103 may specifically include:
and carrying out exclusive OR on each binary code in the second data code and each binary code in the pseudo-random sequence in sequence to obtain the third data code.
In step 103, the step of encrypting the second data code to be transmitted may be implemented by performing a logic operation on the second data code and the pseudo random sequence, and the periodic code in the second data may be eliminated by the second data code and the random sequence. Specifically, the logic operation may be to perform exclusive or on each binary code in the second data code and each binary code in the pseudo random sequence in sequence to obtain a third data code.
Further, the step 104 may specifically include:
under the condition that the third data code is in a data format other than an 8-bit format, carrying out recombination coding on the third data code according to the 8-bit coding format to obtain the MIPI data code;
and under the condition that the coding format of the third data code is an 8-bit format, the third data code is the MIPI data code.
In the step 104, since the second data code to be transmitted may be in a format of 8bit, 10bit, 12bit, or 16bit, etc., the third data code obtained after the second data code is encrypted is still the code in the original format. Since the MIPI interface can only transmit data codes in the 8-bit format, the third data codes need to be recombined and coded when the third data codes are in a data format other than the 8-bit format.
In the embodiment of the present application, if the third data is encoded into a 10-bit format, each 1 group of 10-bit data can be divided into 2 parts, i.e., lower order P [0:1] and upper order P [2:9 ]. Then, taking 4 groups of data as a period, respectively taking out 4 groups of low-order 2-bit data to form a group of 8-bit data, and taking the remaining 4 groups of high-order 8-bit data as the other 4 groups of 8-bit data, which is equivalent to recombining and coding each 4 groups of 10-bit data into 5 groups of 8-bit data, thereby converting the third data codes into 8-bit formats and transmitting the data through an MIPI interface.
In the embodiment of the present application, the LFSR module may be used to implement the process of the data processing method. For convenience of description, the following describes in detail a specific flow of the data processing method by taking N ═ 3 as an example:
defining N to 3, the data code is obtained as the initial state code of the LFSR module, which is assumed to be 001.
The LFSR module generates 2 in a specific sequence according to the initial state code by sequential logic, i.e. by a characteristic polynomial33-bit data for 1 state: 001, 010, 100, 011, 101, 111, 101, 111.
Encoding First 3 bits of second data output by a First In First Out (FIFO) module, and carrying Out XOR between the First 3 bits of second data and the 3 bits of data output by the LFSR module at the 1 st time bit by bit to obtain a First code after random encryption;
and then repeating the process, coding the 3+1 th bit to the 2 x 3 th bit data output by the FIFO module, and carrying out XOR between the bitwise coding and the 3 nd bit data output by the LFSR module at the 2 nd time to obtain a second code after random encryption.
Then, the above-mentioned process is continuously repeated, if the bit number of the above-mentioned second data code is less than 3 (2)3-1), then will beAnd aligning the second data code with the first bit of the pseudo-random sequence, and carrying out bitwise XOR on the second data code to the last bit, namely finishing the encryption processing.
If the number of bits of the second data code is greater than or equal to 3 (2)3-1), then up to the (2) th of the original data3-2) 3+1 to (2)3-1) 3 bits and LFSR 2 nd3-1) completing a period after the data are subjected to XOR for times, and then repeating the period to the last bit of the second data code, namely, finishing the encryption processing.
Assume that the second data is encoded as: 1010100110011010011011101001100001010110, that is, there is a 0110 code at the end of every 10 bits of data, when the first 24 bits of the second data code are:
101 010 011 001 101 001 101 110；
the first 24 bits of the LFSR module output are encoded as:
001010100011101111101111, respectively; and carrying out bitwise XOR on the two codes to finish a period to obtain a code:
100 000 111 010 000 110 000 001
then, the cycle is repeated, and the last 16 bits of the second data code are:
1001100001010110, respectively; the last 16 bits of the LFSR module output are encoded as:
0010101000111011, respectively; carrying out bitwise XOR on the two codes to obtain a code:
1011001001101101, respectively; the finally output third data is encoded as:
1000001110 1000011000 0001101100 1001101101。
it should be noted that the case where N is 3 is merely a case assumed for convenience of illustration, and N may be an integer greater than or equal to 10 in practical applications, so as to completely eliminate the periodic encoding in the second data encoding.
Finally, under the condition that the coding format of the third data code is an 8-bit format, determining the third data code as the MIPI data code;
and under the condition that the third data code is in a data format other than an 8-bit format, carrying out recombination coding on the third data code according to the 8-bit coding format to obtain the MIPI data code.
Continuing with the example with the second data encoding 1010100110011010011011101001100001010110, at this time, the third data encoding 1000001110100001100000011011001001101101 is re-encoded, i.e., 4 sets of lower 2-bit data 10100010 are taken out to form a set of 8-bit data 10100010, and the remaining 4 sets of upper 8-bit data 10100110101001101010011001010110 are the other 4 sets of 8-bit data. Equivalently, 10-bit data of each 4 groups are recombined and coded into 5 groups of 8-bit data, so that the third data code is converted into an 8-bit format, and finally, the MIPI data code with the 8-bit format is obtained: 0000111000011000011011000110110110100010, it can be seen that the code 0110 no longer occurs periodically in the encoding of MIPI data.
