Wherein the test device may retrieve the stored calibration data by running test software. If the test software is developed using C language, since the standard data type with the least number of bits among the plurality of standard data types of C language is a character (char) type corresponding to 8 bits (bits), the number of bits included in the data that can be processed by the test software needs to be equal to or greater than 8 bits.

In the related art, in order to satisfy the requirement that the number of bits is equal to or greater than 8 bits, each calibration data is stored in one byte (byte) of 8 bits, and each calibration data is acquired by parsing each byte of 8 bits. In the case where the calibration data includes less than 8 bits, this way of storing the calibration data will result in a waste of memory resources.

The terminal 11 and the server 12 establish a communication connection through a wired or wireless network.

It should be understood by those skilled in the art that the above-mentioned terminal 11 and server 12 are only examples, and other existing or future terminals or servers may be suitable for the present application and are included within the scope of the present application and are herein incorporated by reference.

The calibration data storage method provided in the embodiment of the present application may be as shown in fig. 2, and the method may be executed by a test device for testing a WiFi chip, and in combination with the implementation scenario shown in fig. 1, the test device may be a terminal 11 or a server 12. As shown in fig. 2, the method includes, but is not limited to, step 201 and step 202.

In step 201, calibration data of a WiFi chip to be calibrated is obtained, and one calibration data is used to calibrate an operating parameter of the WiFi chip.

Illustratively, before acquiring a plurality of calibration data of the WiFi chip to be calibrated, the method further comprises: acquiring a storage instruction, wherein the storage instruction comprises identification information of a WiFi chip to be calibrated; and determining the WiFi chip to be calibrated from the plurality of candidate WiFi chips according to the identification information included in the storage instruction. The method provided by the embodiment of the application can be suitable for a scene with a plurality of candidate WiFi chips, and the test equipment can determine the chip to be calibrated from the plurality of candidate WiFi chips based on the identification information in the acquired storage instruction, so as to execute the processes of acquiring a plurality of calibration data of the WiFi chip to be calibrated and writing the plurality of calibration data into the unit storage space. The embodiment of the application does not limit the manner of obtaining the storage instruction, and the test equipment can generate the storage instruction or receive the storage instruction sent by other equipment.

Whichever way the test device is triggered to determine the WiFi chip to be calibrated, the way for the test device to obtain the plurality of calibration data of the WiFi chip to be calibrated includes but is not limited to: the test equipment generates a plurality of calibration data of the WiFi chip to be calibrated, or receives a plurality of calibration data of the WiFi chip to be calibrated, which are sent by other equipment. The other device sending the plurality of calibration data of the WiFi chip to be calibrated may be the device sending the storage instruction to the test device. In addition, whether the test equipment generates the plurality of calibration data of the WiFi chip to be calibrated or other equipment except the test equipment generates the plurality of calibration data of the WiFi chip to be calibrated, the generating the plurality of calibration data of the WiFi chip to be calibrated includes but is not limited to: acquiring initial values of all working parameters of a WiFi chip to be calibrated; for any one of the operating parameters, calibration data corresponding to the any one of the operating parameters is calculated based on the initial value of the any one of the operating parameters.

In the embodiment of the present application, the operating parameters of the WiFi chip to be calibrated include, but are not limited to, power and frequency offset, and accordingly, the plurality of calibration data includes, but is not limited to, power calibration data and frequency calibration data. The power calibration data is used for calibrating power, and the frequency calibration data is used for calibrating frequency. For example, the power calibration data may comprise 4 bits and the frequency calibration data may comprise 3 bits.

In step 202, a plurality of calibration data are written into the unit memory space.

The unit storage space may be a granularity used by the test device in determining the size of the storage space, in other words, the test device determines the size of the storage space according to an integer multiple of the unit storage space. For example, if the unit storage space is an 8-bit byte, the test device determines the size of the storage space in integer multiples of the 8-bit byte.

In the embodiment of the present application, when the test equipment writes the plurality of calibration data into the unit memory space, the method includes, but is not limited to, writing the plurality of calibration data into the unit memory space in the order in which the plurality of calibration data are acquired. The starting address of the target calibration data in the unit storage space in the plurality of calibration data is indicated by the initial offset value, and the initial offset value and the number of bits corresponding to the target calibration data can be used for reading each bit included in the target calibration data from the unit storage space.

In one possible implementation, writing a plurality of calibration data to a unit memory space includes: based on that the sum of the number of bits included in the plurality of calibration data is less than the number of bits corresponding to the second spare storage space, and the number of bits corresponding to the second spare storage space is less than or equal to the number of bits corresponding to the unit storage space, writing each bit included in the plurality of calibration data and a second number of padding bits into the second spare storage space in sequence, where the second number is a difference between the number of bits corresponding to the second spare storage space and the sum of the number of bits included in the plurality of calibration data; and writing the bits included in the second spare storage space into the unit storage space.

Illustratively, the number of bits corresponding to the second spare storage space is the number of bits required to write data into the unit storage space. In the case that the sum of the number of bits included in the plurality of calibration data is smaller than the number of bits corresponding to the second spare storage space, writing the respective bits of the plurality of calibration data and the second filler bits of the second number into the second spare storage space enables writing the respective bits of the plurality of calibration data into the unit storage space by writing the bits included in the second spare storage space into the unit storage space. In this embodiment, the number of bits corresponding to the second spare storage space may be 8 bits. The test equipment can write the bits included in the second spare memory space into the unit memory space by using the test software using the C language as the development language.

In a possible implementation manner, sequentially writing the respective bits included in the plurality of calibration data and the second number of second padding bits into the second spare memory space includes: writing a jth bit of bits included in the plurality of calibration data into a jth bit position of the second spare storage space, and writing a second number of second padding bits into remaining bit positions of the second spare storage space; wherein j is used for representing a serial number, j is more than or equal to 1 and less than or equal to M or j is more than or equal to 0 and less than or equal to M-1, and M is used for representing the number of bits included by the plurality of calibration data. In the embodiment of the present application, the second padding bit may be 0.

Illustratively, for any one bit in each of the bits included in the plurality of calibration data, when the any one bit is written into the corresponding bit position in the second spare storage space, the bit position corresponding to the any one bit is cleared first, and then the any one bit is written into the cleared bit position. The principle is the same when any one of the second padding bits is written into the corresponding bit position in the second spare storage space, and details are not repeated here.

Regarding the way of writing the bits included in the second spare memory space into the unit memory space, the method includes but is not limited to: for any bit in a plurality of bits included in the second spare storage space, acquiring a storage address corresponding to the any bit in the unit storage space, clearing the storage address corresponding to the any bit, and writing the any bit into the cleared storage address. The storage address corresponding to any one bit may be determined based on a bit position of the any one bit in the second spare storage space and a start address of a bit included in the second spare storage space in the unit storage space.

For example, for the s-th bit in the plurality of bits included in the second spare storage space, the storage address corresponding to the s-th bit is A + s, A is used for indicating the starting address of the bit included in the second spare storage space in the unit storage space, s is used for indicating the sequence number, 1 ≦ s ≦ K or 0 ≦ s ≦ K-1, and K is used for indicating the number of bits included in the second spare byte. For example, in a case where the second spare storage space includes the same number of bits as the number of bits corresponding to the unit storage space, a start address of the bits included in the second spare storage space in the unit storage space may be the same as a start address of the unit storage space. In a case where the number of bits included in the second spare memory space is smaller than the number of bits corresponding to the unit memory space, a start address of each bit included in the second spare memory space in the unit memory space may be the same as or different from a start address of the unit memory space.

In one possible implementation, the unit storage space is a byte of a plurality of consecutive bytes. In this case, the storage address corresponding to the s-th bit may be indicated by a first byte destination index (byte _ dst _ idx) and a first bit destination index (bit _ dst _ idx), where the first byte destination index is used to indicate a start address of the unit storage space, and the first bit destination index is used to indicate a deviation between the storage address corresponding to the s-th bit and the start address of the unit storage space. Taking the example that the start address of the bits included in the second spare memory space in the unit memory space is the same as the start address of the unit memory space, the embodiment of the present application provides a code logic for writing the bits included in the second spare memory space into the unit memory space, where the code logic may be as follows:

in the code logic, the starting address of the unit memory space is represented by bit _ offset, and the number of bits included in the second spare memory space is represented by bit _ cnt. The first byte source index is used for indicating the bit position of the bit in the second spare storage space, and the bit sequence number is represented by bit _ src _ cnt. Thus, in conjunction with the code logic, the s-th bit may be written to the corresponding memory address by performing operations (11) through (14) as follows for the s-th bit in the second spare memory space.

And operation (11) of obtaining a storage location corresponding to the s-th bit based on the bit _ offset, wherein the storage location corresponding to the s-th bit is indicated by the index of the first byte destination and the index of the first bit destination.

And (12) clearing the storage position corresponding to the s-th bit.

In operation (13), the first byte source index of the s-th bit is obtained.

And (14) reading the s-th bit from the second spare storage space according to the first byte source index, and writing the s-th bit into the cleared storage position.

After the operations (11) to (14) are performed on the s-th bit, operations similar to the operations (11) to (14) may be performed on the s + 1-th bit again until each bit of the second spare memory space is written into the corresponding memory location.

Illustratively, after writing the plurality of calibration data into the unit memory space, the method further includes: for any one of the plurality of calibration data, acquiring an offset value corresponding to the any one of the plurality of calibration data according to a start address of the any one of the plurality of calibration data in the unit memory space; and generating the corresponding relation of the working parameters, the deviation values and the bit quantity based on the working parameters, the deviation values and the bit quantity corresponding to the calibration data. Therefore, when target calibration data in the plurality of calibration data is acquired subsequently, the initial offset value and the bit number corresponding to the target calibration data can be acquired by searching the corresponding relation between the working parameter and the offset value and the bit number, and then the target calibration data is acquired.

In the method provided by the embodiment of the application, the plurality of calibration data of the WiFi chip to be calibrated are stored in the unit storage space, so that the utilization rate of the storage resources of the unit storage space is higher. Furthermore, the number of bits included in each calibration data may be different, and the method can be applied to different cases of the number of bits included in the calibration data.

The embodiment of the present application further provides a method for acquiring calibration data, where the method may be executed by a test device for testing a WiFi chip, and with reference to the implementation environment shown in fig. 1, the test device may be a terminal 11 or a server 12. As shown in fig. 3, the method for acquiring calibration data provided in the embodiment of the present application may include the following steps 301 to 304.

In step 301, the operating parameters of the WiFi chip to be calibrated are obtained.

Before obtaining the operating parameters of the WiFi chip to be calibrated, the method may further include: acquiring a calibration instruction, wherein the calibration instruction comprises identification information of a WiFi chip to be calibrated; and determining the WiFi chip to be calibrated from the plurality of candidate WiFi chips according to the identification information included in the calibration instruction. Therefore, after the WiFi chip to be calibrated is determined, the working parameters of the WiFi chip to be calibrated can be obtained according to the determined WiFi chip to be calibrated.

For example, the test equipment stores the operating parameters of each candidate WiFi chip. After the WiFi chip to be calibrated is determined, the test equipment acquires the stored working parameters of the WiFi chip to be calibrated. Of course, the operating parameters of each candidate WiFi chip may also be stored in other devices besides the test device. In this case, after the WiFi chips to be calibrated are determined, the test device may send a working parameter obtaining request to other devices in which the working parameters of each WiFi chip are stored, and receive the working parameters of the WiFi chips to be calibrated, which are returned by the other devices in response to the working parameter obtaining request.

In the embodiment of the application, the test equipment can also directly acquire the working parameters of the WiFi chip to be calibrated, and the WiFi chip to be calibrated does not need to be determined first. For example, the test equipment receives a first instruction input from the outside, the first instruction includes working parameter indication information, and the working parameter indication information is used for indicating the working parameters of the WiFi chip to be calibrated, so that the test equipment can acquire the working parameters of the WiFi chip to be calibrated according to the working parameter indication information. The first instruction may be an instruction sent by the device storing the operating parameters of the WiFi chip to the testing device.

In step 302, an initial offset value and a number of bits corresponding to the target calibration data are obtained based on the operating parameters of the WiFi chip.

Illustratively, the initial offset value is used to indicate a start address of target calibration data used for calibrating the operating parameter in a unit memory space in which a plurality of calibration data are stored.

In a possible implementation manner, acquiring an initial offset value and a bit number corresponding to target calibration data based on operating parameters of a WiFi chip includes: based on the working parameters of the WiFi chip, the corresponding relation between the working parameters and the deviation value and the corresponding relation between the working parameters and the number of bits are inquired, and the initial deviation value and the number of bits corresponding to the target calibration data are obtained. The corresponding relationship between the operating parameter and the offset value and the number of bits may be the corresponding relationship between the operating parameter and the offset value and the number of bits generated in the embodiment of the calibration data storage method shown in fig. 2.

In step 303, the respective bits included in the target calibration data are read from the unit storage space based on the initial offset value and the number of bits.

Illustratively, reading the respective bits included in the target calibration data from the unit storage space based on the initial offset value and the number of bits includes: the address of the unit memory space is acquired, and the respective bits included in the target calibration data are read from the unit memory space based on the initial offset value and the number of bits. For example, if the unit memory space is one of a plurality of consecutive bytes, the address of the unit memory space may be determined first, and the bits included in the target calibration data may be read from the unit memory space.

In this case, the storage address of the i-th bit included in the target calibration data may be indicated by a second byte source index indicating a start address of the unit storage space and a second bit source index indicating a deviation of the storage address of the i-th bit from the start address of the unit storage space. Since the start address of the target calibration data in the unit storage space may be indicated by the initial offset value corresponding to the target calibration data, the second bit source index corresponding to the ith bit may be equal to the initial offset value + i.

In step 304, each bit is parsed to obtain target calibration data.

Illustratively, the target calibration data includes a number of bits that is less than a standard parsing number, which is the number of bits required to perform the data parsing. For example, the standard parsing number is the number of bits for performing data parsing by test software in which C language is a development language. The standard parsing number may be 8 bits. Analyzing each bit to obtain target calibration data, including: writing each bit included in the target calibration data and a first number of first filling bits into a first spare storage space, wherein the number of bits corresponding to the first spare storage space is an integral multiple of the standard parsing number, and the first number is not less than a difference between the standard parsing number and the number of bits of the target calibration data; and performing data analysis on the first spare storage space by taking the standard analysis quantity as a unit to obtain target calibration data. The first spare storage space may be an 8-bit byte and the first padding bit may be 0.

The target calibration data is written into the first spare storage space by taking the first spare storage space as a transfer, data analysis is performed on bits included in the first spare storage space by taking the standard analysis quantity as a unit, and the test software taking the C language as a development language can obtain the target calibration data by analyzing the bits included in the first spare storage space. Therefore, each calibration data does not need to be stored in different unit storage spaces, and the method provided by the embodiment of the application can improve the utilization rate of the storage resources of the unit storage spaces while realizing the acquisition of the target calibration data.

Illustratively, writing the respective bits comprised by the target calibration data and the first number of first filler bits into the first spare memory space comprises: writing an ith bit included in the target calibration data into an ith bit position of the first spare storage space, and writing a first number of first padding bits into the rest bit positions of the first spare storage space; where i is used to represent a sequence number, 1 ≦ i ≦ N or 0 ≦ i ≦ N-1, and N is used to represent the number of bits included in the target calibration data. For any one of the bits included in the target calibration data, when the any one bit is written into the corresponding bit position in the first spare storage space, the corresponding bit position may be cleared first, and the any one bit may be written into the cleared bit position. The principle is the same when any one of the first padding bits is written into the corresponding bit position in the first spare storage space, and details are not repeated here.

In the embodiment of the present application, reading the respective bits included in the target calibration data and writing the respective bits included in the target calibration data into the first spare memory space may be performed alternately. That is, after the ith bit included in the target calibration data is read, the ith bit may be written into the first spare memory space, and then the (i + 1) th bit included in the target calibration data is read, and the (i + 1) th bit may be written into the first spare memory space. By performing the operations of reading and writing bits in an interleaving manner, the read bits can be directly written into the first spare storage space, and the read bits do not need to occupy other storage spaces except the first spare storage space to store the read bits and do not need to be transferred from the other storage spaces to the first spare storage space. The method for performing reading bits and writing bits in an interleaving mode can reduce occupation of storage space, and shorten time from reading each bit to writing each bit into the first spare storage space.

Taking a unit storage space as an example of one of a plurality of consecutive bytes, the present application provides a code logic for writing each bit of target calibration data into a first spare storage space, where the code logic may be as follows:

in the code logic, the starting read address is obtained according to the starting address of the unit memory space and the initial offset value corresponding to the target calibration data, the starting read address ori _ offset represents, and the number of bits included in the target calibration data is represented by target _ cnt. The index of the second byte is used to indicate the bit position of the bit included in the target calibration data in the first spare memory space, and the bit sequence number is represented by bit _ dst _ cnt. Thus, in conjunction with the code logic, an ith bit may be written to an ith bit position in the first spare memory space by performing operations (21) through (24) on an ith bit included in the target calibration data.

Operation (21) obtains a memory address of an i-th bit, which is indicated by the second byte source index and the second bit source index, based on the ori _ offset.

Operation (22) obtains an index of the second byte of the ith bit.

And operation (23) is to clear the bit position of the ith bit in the first spare storage space according to the index of the second byte.

And an operation (24) of reading the ith bit from the storage address of the ith bit and writing the ith bit into the cleared bit position based on the second byte source index and the second bit source index.

After the above operations (21) to (24) are performed on the ith bit, operations similar to the above operations (21) to (24) may be performed on the (i + 1) th bit again until each bit of the target calibration data is written into the corresponding bit position.

Since the number of bits included in the target calibration data may be any value smaller than the number of bits corresponding to the unit memory space, the method is applicable to different cases of the number of bits included in the calibration data. Furthermore, since the unit memory space can store a plurality of calibration data, the memory resource usage rate of the unit memory space is high.
