When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure.

It is further understood that the terms "first," "second," and the like are used to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish one type of information from another and do not denote a particular order or importance. Indeed, the expressions "first", "second", etc. may be used entirely interchangeably. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure.

The mobile industry processor interface (Mobile Industry Processor Interface, MIPI) is an open standard and a specification established for mobile application processors by the MIPI alliance. Three protocols may be included in the physical layer of MIPI: M-PHY, D-PHY, and C-PHY. The three differences are shown in table 1 below:

TABLE 1

Of these three protocols, the data transmission amount of M-PHY is the largest, but there are few cases of M-Phy applications in the imaging field. The main reason is that in connection with the development of the application of the camera, the camera does not continue to develop as much up to higher pixel numbers after reaching 20M pixels as the MIPI organization expects. The development of M-Phy devices is too complex to support by the device manufacturer, and therefore camera devices remain on the D-Phy protocol for a long period of time. Along with the wide application of the high-definition display screen, the communication protocol requirements of the display module on the high-speed bandwidth are also increasing. High-speed communication protocols are required for large data volume transmission, and C-PHYs are increasingly used in camera communication protocols because the speed of the C-PHYs can reach 5.7Gbps and is larger than that of the traditional D-PHYs. And the data transmission process based on the C-PHY protocol is to form symbol codes by continuously changing the signal value state, so that the content of the data transmission is hidden in the symbol codes to finish the data transmission.

In the related art, encoding/decoding is performed on symbol, mainly through a payment plug-in of related instruments such as an oscilloscope. In the present disclosure, by designing a spreadsheet, a mapping relationship is pre-stored in the spreadsheet, and then encoding/decoding is performed according to an initial state of a signal value and a symbol code value corresponding to symbol code or a final state of an adjacent signal value, so that a tester can intuitively interpret information contained in symbol code, determine whether data is transmitted or how to be transmitted, and further perform flexible test. And the matched use of an instrument and a payment plug-in is not needed, so that the cost is saved.

Fig. 1 is a flowchart illustrating an encoding method according to an exemplary embodiment, which may be applied to data transmission based on a C-PHY protocol, as a carrier of data information, during which data information is transmitted in the course of data information transmission in the present disclosure. As shown in fig. 1, the encoding method 10 includes the following steps S11 to S13.

In step S11, a signal value initial state is acquired.

In the embodiment of the disclosure, the C-PHY protocol has no clock line, so the receiving end needs to derive the clock frequency according to the demodulation data change edge in the decoding process. The C-PHY protocol is located at the interface physical layer and includes A, B, C three data lines in each channel in the physical layer, corresponding to a set of differential lines (dp=3/4V, dm =1/4V) and one common mode line dc=1/2V, respectively. A, B, C pieces of data are assigned to a total of 3×2×1=6 permutation combinations of Dp, dm and Dc, respectively, and 6 symbols defining these 6 combinations as +x, -X, +y, -Y, +z and-Z represent the respective signal value states. The signal value initial state may be any one of the 6 signal value states. The signal value initial state may be a designated signal value state, or may be a signal value initial state with a camera device currently under test. The acquisition of the initial state of the signal value is beneficial to determining the data to be transmitted, so that the jump of the state of the signal value is conveniently completed through symbol encoding, and the receiving end can acquire the change frequency of the clock.

In step S12, a symbol code value corresponding to the hopped symbol code value and a symbol code corresponding to the symbol code value in the initial state of the signal value are acquired.

In the disclosed embodiment, the jump from one signal value state to another signal value state is achieved based on Symbol encoding. In the data transmission process of the C-PHY protocol, symbol codes are formed by continuously changing the signal value state, and then data transmission is completed. Different symbol codes are used to characterize different hopping processes that the signal value state will send. In the process of data transmission, symbol codes are carriers of data information. In order to ensure that the data edge at the receiving end can obtain the clock frequency, the data edge changes need to occur, so that each signal value state has 5 valid transitions, i.e. 5 signal value states except for the signal value state of the receiving end. When the signal value state jumps, the receiving end can obtain the clock frequency. If the state of the signal value is not changed, the changed edge cannot be formed, and the receiving end cannot acquire the clock. Different definition numbers are adopted to distinguish different symbol codes according to different jump processes, and the different definition numbers are symbol code values corresponding to the different symbol codes. The definition number includes: <0>, <1>, <2>, <3>, <4>. By acquiring the symbol code value corresponding to the initial state of the signal value, the jump process of the initial state of the signal value can be defined according to the symbol code value. The symbol code value is obtained and the symbol code corresponding to the symbol code value is obtained, which is helpful for a tester to intuitively and clearly determine how the initial state of the signal value jumps according to the symbol code to change into the final state of the signal value,

In step S13, based on the obtained signal value initial state and the symbol code value corresponding to the signal value initial state, the signal value initial state is hopped according to the symbol code corresponding to the symbol code value, and the signal value final state after the signal value initial state is hopped is displayed through the electronic table, so as to complete the coding.

In the embodiment of the disclosure, the acquired initial state of the signal value and the symbol code value corresponding to the initial state of the signal value are input into the electronic table. And according to a C-PHY protocol pre-stored in the electronic table, jumping the initial state of the signal value according to the symbol code corresponding to the acquired symbol code value to obtain the final state of the corresponding signal value, displaying the final state through the electronic table, and finishing the code of data transmission. The process of jumping the signal value initial state is displayed through the electronic table, so that a tester can know how to convert line voltages in channels corresponding to the signal value initial state into signal value final states according to symbol codes when jumping occurs, and data transmission is completed. For example: given that the initial state of the signal value is +X, the symbol code value is 2, and the corresponding symbol code is [0,1,0], the clockwise rotation of the initial state of the signal value is indicated, the final state of the signal value is +Y, and the transmission of the symbol code is [0,1,0] in the process. And the process of jumping the initial state of the signal value is displayed through the electronic table, so that the operation is convenient, the method is simple and easy to learn, and the test experience of a tester is convenient to improve.

In practical application, when each signal value state is transmitted to the receiving end, the voltage difference between the data lines in each signal value state is compared through the comparator arranged at the receiving end. The comparison result is greater than 0 and is 1, and the comparison result is less than 0 and is 0. Therefore, the receiving end can obtain the values of rx_ab, rx_bc and rx_ca, that is, the signal output received by the receiving end in the signal value state. The correspondence between the signal value states and the signal voltages of the corresponding data lines, the voltage differences between the data lines obtained by the receiving-end comparator, and the signal outputs received by the receiving end can be as shown in the following table 2:

TABLE 2

The C-PHY protocol includes the signal voltages corresponding to the signal value states shown in table 2, the voltage differences obtained by the comparators at the receiving ends, the corresponding relations between the signal outputs received by the receiving ends, and the signal value state change rules represented by the symbol codes and the corresponding symbol code values. The process of changing the state of the signal value once corresponds to the occurrence of a data change, i.e. transmitting a bit of data. While there are five possibilities for the change in signal value state, it can be understood that the transmission of symbol is 5. Since in practical application, the transmission is based on a machine, the number of 5 bits is represented by a binary system of 3 bits (bits) in the transmission process. The [ Flip, rotation, parity ] character set formed by the attribute combination of 3 bits of "Flip-flop", "Rotation-Rotation", "parity-polarity" represents 5 symbol codes. I.e. 5 symbols are binary equivalent to: <0> = [0, 0]; <1> = [0, 1]; <2> = [0,1,0]; <3> = [0, 1]; <4> = [1, 0]. In 5 symbol codes, only the binary of the first bit of <4> = 100 is 1, the bits of the other 4 symbols are all 0, and the first bit Flip represents "Flip". Thus, as shown in fig. 2, based on the C-PHY protocol, the Symbol coding change principle has the following provisions:

When flip=1, rotation, polority is inactive, rotation, polority can be any binary number in symbol encoding, i.e., the binary of symbol encoding can be denoted as [1, x ], and in practice, is commonly denoted as [1, 0], indicating that the signal value state is inverted, for example: the initial state of the signal value is +X, and the signal value becomes-X through jump of symbol code to [1,0 ]. The initial state of the signal value is-Y, and the signal value becomes +Y after the jump of symbol code to [1,0 ].

When flip=0, the signal value initial state does not Flip, and Rotation, polority is valid. Rotation indicates Rotation, and the order of definition of X- > Y- > Z- > X is positive Rotation, and the order of definition of X- > Z- > Y- > X is negative Rotation. Polority indicates whether the polarity is changed, i.e., whether the "+", "-" signs are changed.

(1) Rotation=0, porosity=0: as shown in fig. 2, the reverse order is shown with the sign unchanged.

(2) Rotation=0, porosity=1: representing the reverse order, the sign change.

(3) Rotation=1, porosity=0: indicating positive order, the sign is unchanged.

Rotation=1, porosity=1: positive sequence and sign change are indicated.

In one implementation, table 2 and signal value state change rules characterized by the respective symbol codes and corresponding symbol code values are stored in advance in a spreadsheet. In order to facilitate the tester to quickly determine the signal value state change rule corresponding to each symbol code, each symbol code and the corresponding symbol code value and the corresponding signal value state change rule may be formed into a table as shown in table 3 below and stored in a spreadsheet.

symbol	Flip	Rotation	Polority	Change rule
					0	0	0	0	Reverse order, homopolarity
1	0	0	1	Reverse order, reverse polarity
					2	0	1	0	Sequentially, of the same polarity
3	0	1	1	Sequentially, reversed polarity
					4	1	0	0	Overturning

TABLE 3 Table 3

Before the acquired initial state of the signal value is hopped according to the acquired symbol code, a signal value state hopping table for hopping each signal value state to other signal value states based on each symbol code may be acquired in advance, for example, as shown in table 4:

TABLE 4 Table 4

Through the signal value state jump table, a tester can intuitively and clearly know the corresponding jump situation which can be obtained when the signal value state jumps based on each symbol code, and further, the process of transmitting data content when data transmission is carried out based on the C-PHY protocol can be clearly understood. In the electronic table, when coding is performed according to the acquired initial state of the signal value and the corresponding symbol code value, the possibility of all symbol code values and all corresponding initial states of the signal value in table 4 can be traversed through codes, a jump result corresponding to the acquired corresponding symbol code value generated in the acquired initial state of the signal value is determined through a logic relation, a final state of the signal value after the jump of the initial state of the signal value is obtained, and the final state of the signal value is displayed through the electronic table.

In another implementation scenario, in order to facilitate a tester to visually and clearly observe a channel voltage change when jumping from one signal value state to another signal value state and a change of each voltage difference in the receiving-end comparator and a change of a receiving-end received signal value when encoding based on a C-PHY protocol, the channel voltage corresponding to the signal value initial state, each voltage difference in the receiving-end comparator and the signal value received by the receiving-end can be acquired together while the signal value initial state is acquired as shown in the following table 5, a signal value final state is obtained by jumping based on the acquired symbol encoding value, and the channel voltage corresponding to the signal value final state, each adjacent voltage difference in the receiving-end comparator and the signal value received by the receiving-end are displayed together.

TABLE 5

Through the above embodiment, the acquired initial state of the signal value is hopped according to the corresponding symbol code value, and the hopped final state of the signal value is displayed through the electronic table. When the transmission test is carried out, a tester can visually acquire the jump process of the initial state of the signal value from the electronic table, and further the flexible test is facilitated. And the electronic form is used for testing, so that the test is convenient and quick, a tester can quickly complete the test, and the test experience is more friendly.

In an embodiment, in order to make it easier for a tester to determine more intuitively and clearly the change of signal voltage values of 3 data lines a\b\c in the physical layer before and after the jump of the initial state of the signal value. Based on the signal value initial signal voltage included in the signal value initial state, namely the signal voltage corresponding to the A\B\C three lines in the channel in the signal value initial state, and the signal value final signal voltage included in the signal value final state, namely the signal voltage corresponding to the A\B\C three lines in the channel in the signal value final state. The signal voltage jump process diagram is generated through the electronic form, and the electronic form can be directly utilized to obtain the signal voltage jump process diagram without connecting an oscilloscope, so that the method is convenient and quick. In the signal voltage jump process diagram, the voltage change of the voltage value of 3 data lines A\B\C from the signal value initial signal voltage jump to the signal value final signal voltage can be clearly seen, and further a tester can flexibly test according to the diagram result. In an implementation scenario, a signal value state encoding process shown in table 5 is adopted, where a signal value initial state+x jumps the signal state into a signal value final state-X through a symbol encoding value, and a signal voltage jump process diagram shown in fig. 3 is generated based on a signal value initial signal voltage included in the signal value initial state+x and a signal value final signal voltage included in the signal value final state-X. The signal voltage hopping process diagram is generated through the electronic table, so that a tester can intuitively determine the hopping process of the initial state of the signal value according to the generated signal voltage hopping process diagram, and further the tester can be helped to read the symbol code.

In another embodiment, the signal value initial state further includes a signal value initial differential voltage, that is, a voltage difference between the data lines in the receiving-end comparator and a voltage corresponding to the a\b\c three lines in the channel. The signal value termination state further includes: the signal value is the final differential voltage, namely the voltage difference between the data lines in the receiving end comparator of the voltage corresponding to the A\B\C three lines in the channel. The differential voltage jump process diagram is generated through the electronic table, and the electronic table can be directly utilized to obtain the differential voltage jump process diagram without connecting an oscilloscope, so that the differential voltage jump process diagram is convenient and quick. In the differential voltage jump process diagram, the change of the voltage difference between the lines acquired by the receiving end in the initial state of the signal value after jump and the adjacent voltage difference of the lines acquired by the receiving end can be clearly seen, and therefore a tester can flexibly test according to the diagram result. In an implementation scenario, a signal value state encoding process shown in table 5 is adopted, where a signal value initial state+x jumps the signal state into a signal value final state-X through a symbol encoding value, and a differential voltage jump process diagram shown in fig. 4 is generated based on a signal value initial differential voltage included in the signal value initial state+x and a signal value final differential voltage included in the signal value final state-X. The electronic table is used for generating the differential voltage jump process diagram, so that a tester can intuitively determine the jump process of the initial state of the signal value according to the generated differential voltage jump process diagram, and further the tester is facilitated to read the symbol code.

Fig. 5 is a flowchart of an encoding method according to an exemplary embodiment, and as shown in fig. 5, the encoding method 20 includes the following steps S21 to S24.

In step S21, a signal value initial state is acquired.

In step S22, one or more binary transmission data are acquired.

In the disclosed embodiment, the binary transmission data is formed based on a plurality of continuous symbol codes, and each binary transmission data corresponds to a plurality of continuous symbol codes respectively and is used for representing a plurality of continuous jump processes of signal value states. The binary transmission data can be obtained, so that the problem which is easy to generate in the transmission data can be found based on continuous multiple jumps of multiple signal value states, the problem can be found in time, and the test efficiency is improved. In practical application, the transmission data is data transmission in units of "words", and in the transmission process, the transmission is performed in 16-bit binary data, so that the acquired binary transmission data may be 16-bit binary transmission data. By this binary transmission data, a continuous transition process of the initial state of the signal value can be determined.

In step S23, based on each binary transmission data, a plurality of symbol codes corresponding to the signal value initial state and a symbol code value corresponding to each symbol code, which are continuously hopped for a plurality of times, are acquired and displayed through the electronic table.

In the embodiment of the disclosure, numbers on each bit in binary transmission data are different, and the corresponding signal value states are subjected to a plurality of continuous jump processes. The mapping relation between the binary transmission data and the plurality of symbol codes is stored in the electronic table in advance. And converting the acquired binary transmission data into a plurality of corresponding continuous symbol codes according to the mapping relation, and further obtaining a plurality of continuous jump processes of the initial state of the signal value, so that a tester can clearly transmit the data content. And displaying each symbol code and the corresponding symbol code value through the electronic table, so that a tester can intuitively acquire the initial state of the signal value and the specific jump condition that a plurality of continuous jumps will occur. And each time a jump is performed, the obtained signal value final state is the signal value initial state of the next jump.

In step S24, based on the obtained signal value initial state and the symbol code value corresponding to the signal value initial state, the signal value initial state is hopped according to the symbol code corresponding to the symbol code value, and the signal value final state after the signal value initial state is hopped is displayed through the electronic table, so as to complete the coding.

In the present disclosure, the embodiments of step S21 and step S24 are the same as the embodiments of step S11 and step S13 in the encoding method 10, respectively, and will not be described in detail herein.

With the above-described embodiment, the mapping relationship between the binary transmission data and the plurality of symbol codes is stored in the electronic form in advance. And converting the acquired binary transmission data into a plurality of continuous symbol codes according to the mapping relation, further determining a jump result of the initial state of the signal value under each symbol code, and displaying the jump result through a spreadsheet. The tester can intuitively and clearly determine how to transmit the data information carried by the symbol code based on the C-PHY protocol by obtaining the signal value final state after each jump in the process of continuously jumping the signal value initial state when the data transmission is performed based on the C-PHY protocol.

In an implementation scenario, since the 16-bit binary transmission data is transmitted in the data transmission process, the 16-bit binary transmission data and the 5-system symbol code value form a mapping relationship to obtain 2 ¹⁶ ＝5 ^x Wherein x is an integer, and the physical meaning of the representation is the transmission number (bit number) of the mapping of the 16bit binary number to the 5 system symbol code value. To ensure that 16bit binary numbers can all be mapped, 2 is needed to be mapped ¹⁶ The number of =65536 is all contained in 5 ^x Within, there is 5 thus a need to satisfy the inequality ^(x-1) ＜2 ¹⁶ ＜5 ^x Further, x=7 is obtained. And 5 ⁶ ＜2 ¹⁶ ＜5 ⁷ Therefore, 7 can be satisfied to map all 16bit binary numbersThe number of transmissions (number of bits) of symbol encoded values, and thus, it follows that transmission data by 16bit binary can be mapped into 7 symbol encoded values of 5 bits. In the C-PHY protocol specification, the mapping relationship between 16bit binary transmission data and 7 symbol codes may be as shown in fig. 6: the mapping relation between each segment of 16bit binary transmission data and 7 successive symbol codes depends on the number of Flip contained in the 7 symbol codes. For example: when no Flip occurs in the 7 symbol codes, the mapping relationship between the 16bit binary transmission data between 0x0000 and 0x3fff and each symbol code is as follows: flip [6:0 ]]＝＝0x00＝＝[0,0,0,0,0,0,0]

[0,0,ro6,po6,ro5,po5,ro4,po4,ro3,po3,ro2,po2,rp1,po1,rp0,po0]Wherein rp0, po0 represent symbol-encoded [0, rotation ] of the 1 st transition ₀ ,Polority ₀ ]Rp1, po1 represent the symbol encoded [0, rotation ] in the occurrence of transition 2 ₁ ,Polority ₁ ]Similarly, ro6, po6 represent the symbol encoded [0, rotation ] in the occurrence of the 7 th transition, respectively ₆ ,Polority ₆ ]. When one Flip occurs in the 7 symbol codes, the mapping relationship between the 16bit binary transmission data between 0x4000 and 0x4fff and each symbol code is as follows: flip [6:0 ] ]＝＝0x01＝＝[0,0,0,0,0,1,0][0,1,0,0,ro6,po6,ro5,po5,ro4,po4,ro3,po3,ro2,po2,rp1,po1]Symbol code for the first jump of signal value initial state is considered to be [1,0 ]]The mapping relationship of the remaining 6 symbols is the same as the case when Flip does not occur in the 7 symbol codes.

Since data transmission based on the C-PHY protocol is used in the physical layer, the mapping relationship between 16bit binary transmission data and 7 symbol codes can be implemented through a circuit diagram as shown in fig. 7, and the logic of the circuit is implemented in a spreadsheet through codes. The data on the left side of the circuit diagram is corresponding 16bit binary transmission data, and the corresponding relation between the corresponding number on each bit and each symbol code on the right side of the circuit diagram is according to. And the data between the 0 th bit data and the 7 th bit data in the 16bit binary transmission data are formed by low bit data and high bit data, wherein the data are in groups from low bit data to high bit data, each group corresponds to a rotation bit and a polarity bit in the corresponding symbol code, and the symbol codes from the 1 st time to the 5 th time of control signal value state transition are determined. The data between the 8 th bit and the 15 th bit are from high bit to low bit, and the corresponding relation between the acquired 16bit binary transmission data and the Flip is determined, which section of symbol code mapping relation shown in fig. 6 belongs to, and then 7 continuous symbol codes are acquired (for convenience of representation, in table 6 and the follow-up tables, symbol shorthand is symbol). Its physical and logical relationship can be as shown in tables 6 and 7, for example: when the value of mux0 (switch 0) is 0, mux0 is closed, and symbol code (sym 0) for the first transition is [0, 1]. When the value of muxa1 is 1 and the value of muxb1 is 0, then muxa1 is open and muxb1 is closed, and symbol code (sym 1) for the second transition is [0, 1].

					sym0	0	1	1	3
sym1	0	1	1	3
					sym2	0	1	1	3
sym3	0	1	1	3
					sym4	1	0	0	4
sym5	0	1	1	3
					sym6	1	0	0	4

TABLE 7

In yet another implementation scenario, to facilitate the spreadsheet being able to directly use the conversion logic between the 16bit binary transmission data and the 7 symbol encodings in the circuit diagram of FIG. 7, tables 6 and 7 may be pre-stored in the spreadsheet. When the method is used, any set of appointed 16-bit binary transmission data can be input into the electronic table, and according to the mapping relation between the 16-bit binary transmission data and 7 symbol codes pre-stored in the electronic table, 7 continuous symbol codes are obtained and displayed in an appointed area of the electronic table in sequence, so that the initial state of the acquired signal value can be continuously hopped according to the obtained symbol codes, and the data can be transmitted. In the continuous hopping process, the signal value final state obtained by hopping each time can be displayed through the electronic table, so that a tester can easily read the process of data transmission based on symbol coding, and the process of coding based on the C-PHY protocol can be quickly known. For example: as shown in table 7, the symbol code values corresponding to the obtained continuous 7 symbol codes were 3,3,3,3,4,3,4, respectively, and 7 continuous signal value states were also obtained as shown in table 8. And then obtaining the voltage value of each data line corresponding to each signal value state and each adjacent voltage difference value in the receiving end comparator.

The decryption process is based on the states of two adjacent signal values, so as to obtain the transmitted data content, namely symbol codes. The initial state of the signal value and the final state of the signal value corresponding to the initial state of the signal value are two adjacent signal value states. And then, the signal value initial state and the signal value final state corresponding to the signal value initial state are obtained, so that the data content transmitted from the signal value initial state to the signal value final state can be obtained for decoding.

The process of jumping the initial state of the signal value is decoded and displayed through the electronic table, so that a tester can be helped to determine the jumping process based on which initial state of the signal value becomes the final state of the signal value, and further the test experience of the tester is prompted. The decoding process based on the C-PHY protocol is to obtain symbol codes by realizing given adjacent two signal value states according to a comparator of an analog receiving end.

In one implementation, table 2 and signal value state change rules characterized by the respective symbol codes and corresponding symbol code values are stored in advance in a spreadsheet.
