[0049] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe in detail the embodiments of the present application with reference to the accompanying drawings.

[0050] After manufacturing a WiFi chip, a test device for testing the WiFi chip needs to obtain stored calibration data, and then use the calibration data to calibrate the working parameters of the WiFi chip so that the values of the calibrated working parameters meet the working requirements of the WiFi chip. Among them, the test device can obtain the stored calibration data by running test software. If the test software is developed in the C language, since among multiple standard data types in the C language, the standard data type with the least number of bits is the character (char) type corresponding to 8 bits (bit), therefore, for the data that the test software can process, the number of bits it includes needs to be greater than or equal to 8 bits.

[0051] In the related art, to meet the requirement that the number of bits is greater than or equal to 8 bits, each calibration data is respectively stored in an 8-bit byte, and each calibration data is obtained by parsing each 8-bit byte. In the case where the number of bits included in the calibration data is less than 8 bits, this way of storing calibration data will cause waste of storage resources.

[0052] An embodiment of the present application proposes a method for obtaining calibration data and a method for storing calibration data, which are used to obtain a target calibration data among multiple calibration data stored in a unit storage space, and improve the utilization rate of storage resources in the unit storage space. Figure 1 It shows a schematic diagram of an implementation environment provided by an embodiment of the present application. The implementation environment may include: a terminal 11 and a server 12.

[0053] The method for obtaining calibration data provided by an embodiment of the present application can be executed by the terminal 11, or can be executed by the server 12, or can be jointly executed by the terminal 11 and the server 12. The embodiment of the present application does not limit this. That is, both the terminal 11 and the server 12 can be used as test devices for testing the WiFi chip. Exemplarily, for the case where the method for obtaining calibration data provided by an embodiment of the present application is jointly executed by the terminal 11 and the server 12, the server 12 undertakes the main computing work, and the terminal 11 undertakes the secondary computing work; or, the server 12 undertakes the secondary computing work, and the terminal 11 undertakes the main computing work; or, a distributed computing architecture is adopted between the server 12 and the terminal 11 for collaborative computing.

[0054] The calibration data storage method provided by the embodiments of this application can be executed by the terminal 11, or by the server 12, or jointly by the terminal 11 and the server 12. The embodiments of this application do not limit this. For the case where the calibration data storage method provided by the embodiments of this application is jointly executed by the terminal 11 and the server 12, the server 12 undertakes the main computing work and the terminal 11 undertakes the secondary computing work; or, the server 12 undertakes the secondary computing work and the terminal 11 undertakes the main computing work; or, a distributed computing architecture is adopted between the server 12 and the terminal 11 for collaborative computing.

[0055] It should be noted that the execution device of the calibration data acquisition method and the execution device of the calibration data storage method can be the same or different. The embodiments of this application do not limit this.

[0056] In a possible implementation, the terminal 11 can be any electronic product that can perform human-computer interaction with the user in one or more ways such as a keyboard, a touchpad, a touch screen, a remote control, voice interaction, or a handwriting device. For example, a PC (Personal Computer), a mobile phone, a smart phone, a PDA (Personal Digital Assistant), a wearable device, a PPC (Pocket PC), a tablet computer, a smart car machine, a smart TV, a smart speaker, a smart voice interaction device, a smart home appliance, a vehicle-mounted terminal, an aircraft, etc. The server 12 can be a single server, a server cluster composed of multiple servers, or a cloud computing service center. The terminal 11 and the server 12 establish a communication connection through a wired or wireless network.

[0057] Those skilled in the art should understand that the above-mentioned terminal 11 and server 12 are only examples. Other existing or future terminal or server that can be applied to this application should also be included within the protection scope of this application and are hereby incorporated by reference.

[0058] The calibration data storage method provided by the embodiments of this application can be as Figure 2 shown. This method can be executed by a test device for testing a WiFi chip. Combining with the Figure 1 illustrated implementation scenario, this test device can be the terminal 11 or the server 12. As Figure 2 shown, this method includes but is not limited to step 201 and step 202.

[0059] In step 201, multiple calibration data of the WiFi chip to be calibrated are obtained, and one calibration data is used to calibrate one working parameter of the WiFi chip.

[0060] Exemplarily, before obtaining multiple calibration data of the WiFi chip to be calibrated, the method further includes: obtaining a storage instruction, where the storage instruction includes identification information of the WiFi chip to be calibrated; determining the WiFi chip to be calibrated from multiple candidate WiFi chips according to the identification information included in the storage instruction. The method provided by the embodiments of the present application can be applicable to scenarios where there are multiple candidate WiFi chips. The test device can determine the chip to be calibrated from multiple candidate WiFi chips based on the identification information in the obtained storage instruction, and then execute the process of obtaining multiple calibration data of the WiFi chip to be calibrated and subsequent writing of the multiple calibration data into the unit storage space. The embodiments of the present application do not limit the manner of obtaining the storage instruction. The test device can generate the storage instruction or receive the storage instruction sent by other devices.

[0061] Regardless of which method is used to trigger the test device to determine the WiFi chip to be calibrated, the methods for the test device to obtain multiple calibration data of the WiFi chip to be calibrated include but are not limited to: the test device generates multiple calibration data of the WiFi chip to be calibrated, or the test device receives multiple calibration data of the WiFi chip to be calibrated sent by other devices. Among them, the other device that sends multiple calibration data of the WiFi chip to be calibrated can be the device that sends the storage instruction to the test device. In addition, whether the multiple calibration data of the WiFi chip to be calibrated are generated by the test device or by other devices other than the test device, generating multiple calibration data of the WiFi chip to be calibrated includes but is not limited to: obtaining the initial values of the respective operating parameters of the WiFi chip to be calibrated; for any one of the respective operating parameters, calculating the calibration data corresponding to the any one of the operating parameters based on the initial value of the any one of the operating parameters.

[0062] In the embodiments of the present application, the operating parameters of the WiFi chip to be calibrated include but are not limited to power and frequency offset. Correspondingly, the multiple calibration data include but are not limited to power calibration data and frequency calibration data. Among them, the power calibration data is used to calibrate the power, and the frequency calibration data is used to calibrate the frequency. For example, the power calibration data can include 4 bits, and the frequency calibration data can include 3 bits.

[0063] In step 202, write the multiple calibration data into the unit storage space.

[0064] Among them, the unit storage space can be the granularity used by the test device when 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 a byte of 8 bits, the test device determines the size of the storage space according to an integer multiple of the byte of 8 bits.

[0065] In an embodiment of the present application, when a test device writes multiple calibration data into a unit storage space, it includes, but is not limited to, writing the multiple calibration data into the unit storage space in the order of obtaining the multiple calibration data. The starting address of the target calibration data among the multiple calibration data in the unit storage space is indicated by an initial offset value, and the initial offset value and the number of bits corresponding to the target calibration data can be used to read each bit included in the target calibration data from the unit storage space.

[0066] In a possible implementation manner, writing the multiple calibration data into the unit storage space includes: based on the sum of the number of bits included in the multiple calibration data being less than the number of bits corresponding to a second spare storage space, and the number of bits corresponding to the second spare storage space being less than or equal to the number of bits corresponding to the unit storage space, sequentially writing each bit included in the multiple calibration data and a second number of padding bits into the second spare storage space, where the second number is the difference between the number of bits corresponding to the second spare storage space and the sum of the number of bits included in the multiple calibration data; writing the bits included in the second spare storage space into the unit storage space.

[0067] Exemplarily, 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. When the sum of the number of bits included in the multiple calibration data is less than the number of bits corresponding to the second spare storage space, by writing each bit of the multiple calibration data and the second number of second padding bits into the second spare storage space, it is possible to write each bit of the multiple calibration data into the unit storage space by writing the bits included in the second spare storage space into the unit storage space. In an embodiment of the present application, the number of bits corresponding to the second spare storage space can be 8 bits. Thus, the test device can use a test software developed in the C language to write the bits included in the second spare storage space into the unit storage space.

[0068] In a possible implementation manner, sequentially writing each bit included in the multiple calibration data and a second number of second padding bits into the second spare storage space includes: writing the j-th bit among each bit included in the multiple calibration data into the j-th bit position of the second spare storage space, and writing the second number of second padding bits into the remaining bit positions of the second spare storage space; where j is used to represent the serial number, 1 ≤ j ≤ M or 0 ≤ j ≤ M - 1, and M is used to represent the number of bits included in the multiple calibration data. In an embodiment of the present application, the second padding bit can be 0.

[0069] Exemplarily, for any one of the bits included in the multiple calibration data, when writing the any one bit to the corresponding bit position in the second spare storage space, first clear the corresponding bit position of the any one bit, and then write the any one bit to the cleared bit position. The principle is the same when writing any one of the second padding bits to the corresponding bit position in the second spare storage space, and will not be elaborated here.

[0070] Regarding the method of writing the bits included in the second spare storage space to the unit storage space, it includes but is not limited to: for any one of the multiple bits included in the second spare storage space, obtain the storage address corresponding to the any one bit in the unit storage space, clear the storage address corresponding to the any one bit, and write the any one bit to the cleared storage address. The storage address corresponding to the any one bit can be determined based on the bit position of the any one bit in the second spare storage space and the starting address of the bits included in the second spare storage space in the unit storage space.

[0071] For example, for the s-th bit among the multiple bits included in the second spare storage space, the storage address corresponding to the s-th bit is A + s, where A is used to represent the starting address of the bits included in the second spare storage space in the unit storage space, s is used to represent the serial number, 1 ≤ s ≤ K or 0 ≤ s ≤ K - 1, and K is used to represent the number of bits included in the second spare byte. Exemplarily, when the number of bits included in the second spare storage space is the same as the number of bits corresponding to the unit storage space, the starting address of the bits included in the second spare storage space in the unit storage space can be the same as the starting address of the unit storage space. When the number of bits included in the second spare storage space is less than the number of bits corresponding to the unit storage space, the starting addresses of the respective bits included in the second spare storage space in the unit storage space can be the same as or different from the starting address of the unit storage space.

[0072] In a possible implementation manner, the unit storage space is a certain byte among multiple consecutive bytes. In this case, the storage address corresponding to the s-th bit can be indicated by a first byte destination index (byte destinationindex, byte_dst_idx) and a first bit destination index (bit destination index, bit_dst_idx), where the first byte destination index is used to indicate the starting address of the unit storage space, and the first bit destination index is used to indicate the deviation between the storage address corresponding to the s-th bit and the starting address of the unit storage space. Taking the starting address of the bits included in the second spare storage space in the unit storage space being the same as the starting address of the unit storage space as an example, the embodiments of the present application provide a code logic for writing the bits included in the second spare storage space to the unit storage space, and the code logic can be as follows:

[0073]

[0074]

[0075] In this code logic, the starting address of the unit storage space is represented by bit_offset, and the number of bits included in the second spare storage space is represented by bit_cnt. The first byte source index is used to indicate the bit position of the bits in the second spare storage space within the second spare storage space, and the bit sequence number is represented by bit_src_cnt. Thus, in combination with this code logic, the s-th bit in the second spare storage space can be written to the corresponding storage address by performing the following operations (11) to (14).

[0076] Operation (11): Based on bit_offset, obtain the storage position corresponding to the s-th bit, and the storage position corresponding to the s-th bit is indicated by the first byte destination index and the first bit destination index.

[0077] Operation (12): Clear the storage position corresponding to the s-th bit.

[0078] Operation (13): Obtain the first byte source index of the s-th bit.

[0079] Operation (14): Read the s-th bit from the second spare storage space according to the first byte source index, and write the s-th bit to the cleared storage position.

[0080] After performing the above operations (11) to (14) on the s-th bit, similar operations to the above operations (11) to (14) can be performed on the s + 1-th bit until all bits in the second spare storage space are written to the corresponding storage positions.

[0081] Exemplarily, after writing multiple calibration data into the unit storage space, it further includes: for any one of the multiple calibration data, obtain the offset value corresponding to the any one of the calibration data according to the starting address of the any one of the calibration data in the unit storage space; generate the corresponding relationship between the working parameters, the offset value, and the number of bits based on the working parameters, the offset values, and the number of bits corresponding to each calibration data. Thus, when subsequently obtaining the target calibration data among the multiple calibration data, the initial offset value and the number of bits corresponding to the target calibration data can be obtained by looking up the corresponding relationship between the working parameters, the offset value, and the number of bits, and then the target calibration data can be obtained.

[0082] In the method provided by the embodiment of the present application, by storing multiple calibration data of the WiFi chip to be calibrated in a unit storage space, the storage resource utilization rate of the unit storage space is relatively high. Moreover, the number of bits included in each calibration data can be different, and this method can be applicable to different situations of the number of bits included in the calibration data.

[0083] The embodiment of the present application further provides a method for obtaining calibration data. This method can be executed by a test device for testing a WiFi chip. Combining Figure 1 with the shown implementation environment, this test device can be the terminal 11 or the server 12. As Figure 3 shown, the method for obtaining calibration data provided by the embodiment of the present application can include the following steps 301 to 304.

[0084] In step 301, obtain the working parameters of the WiFi chip to be calibrated.

[0085] Exemplarily, before obtaining the working parameters of the WiFi chip to be calibrated, this method further includes: obtaining a calibration instruction, where the calibration instruction includes the identification information of the WiFi chip to be calibrated; determining the WiFi chip to be calibrated from multiple candidate WiFi chips according to the identification information included in the calibration instruction. Thus, after determining the WiFi chip to be calibrated, the working parameters of the WiFi chip to be calibrated can be obtained according to the determined WiFi chip to be calibrated.

[0086] For example, the test device stores the working parameters of each candidate WiFi chip. After determining the WiFi chip to be calibrated, the test device obtains the stored working parameters of the WiFi chip to be calibrated. Of course, the working parameters of each candidate WiFi chip can also be stored in other devices outside the test device. In this case, after determining the WiFi chip to be calibrated, the test device can send a working parameter acquisition request to other devices storing the working parameters of each WiFi chip, and receive the working parameters of the WiFi chip to be calibrated returned by other devices in response to the working parameter acquisition request.

[0087] In the embodiment of the present application, the test device can also directly obtain the working parameters of the WiFi chip to be calibrated without first determining the WiFi chip to be calibrated. For example, the test device receives a first instruction input externally, where the first instruction includes working parameter indication information for indicating the working parameters of the WiFi chip to be calibrated, so that the test device can obtain the working parameters of the WiFi chip to be calibrated according to the working parameter indication information. The first instruction can be an instruction sent by a device storing the working parameters of the WiFi chip to the test device.

[0088] In step 302, based on the working parameters of the WiFi chip, obtain the initial offset value and the number of bits corresponding to the target calibration data.

[0089] Exemplarily, the initial offset value is used to indicate the starting address of the target calibration data in the unit storage space. The target calibration data is used to calibrate the working parameters, and multiple calibration data are stored in the unit storage space.

[0090] In a possible implementation manner, obtaining the initial offset value and the number of bits corresponding to the target calibration data based on the working parameters of the WiFi chip includes: querying the correspondence between the working parameters and the offset value and the number of bits based on the working parameters of the WiFi chip, and obtaining the initial offset value and the number of bits corresponding to the target calibration data. The correspondence between the working parameters and the offset value and the number of bits can be the correspondence generated in the embodiment of the storage method of the calibration data shown above Figure 2 shown in the embodiment of the storage method of the calibration data.

[0091] In step 303, based on the initial offset value and the number of bits, read each bit included in the target calibration data from the unit storage space.

[0092] Exemplarily, reading each bit included in the target calibration data from the unit storage space based on the initial offset value and the number of bits includes: obtaining the address of the unit storage space, and reading each bit included in the target calibration data from the unit storage space based on the initial offset value and the number of bits. For example, if the unit storage space is a certain byte among a continuous plurality of bytes, the address of the unit storage space can be determined first, and then each bit included in the target calibration data can be read from the unit storage space.

[0093] In this case, the storage address of the i-th bit included in the target calibration data can be indicated by the second byte source index and the second bit source index, where the second byte source index is used to indicate the starting address of the unit storage space, and the second bit source index is used to indicate the deviation of the storage address of the i-th bit from the starting address of the unit storage space. Since the starting address of the target calibration data in the unit storage space can be indicated by the initial offset value corresponding to the target calibration data, the second bit source index corresponding to the i-th bit can be equal to the initial offset value + i.

[0094] In step 304, perform parsing processing on each bit to obtain the target calibration data.

[0095] Exemplarily, the number of bits included in the target calibration data is less than the standard parsing quantity, where the standard parsing quantity is the number of bits required for performing data parsing. For example, the standard parsing quantity is the number of bits for performing data parsing by a test software developed in C language. The standard parsing quantity may be 8 bits. By performing parsing processing on each bit, the target calibration data is obtained, including: writing each bit included in the target calibration data and a first quantity of first padding bits into a first spare storage space, where the number of bits corresponding to the first spare storage space is an integer multiple of the standard parsing quantity, and the first quantity is not less than the difference between the standard parsing quantity and the number of bits of the target calibration data; and performing data parsing on the first spare storage space in units of the standard parsing quantity to obtain the target calibration data. The first spare storage space may be an 8-bit byte, and the first padding bits may be 0.

[0096] By using the first spare storage space as a transfer medium, writing the target calibration data into the first spare storage space, and then performing data parsing on the bits included in the first spare storage space in units of the standard parsing quantity, the test software developed in C language can obtain the target calibration data by parsing the bits included in the first spare storage space. Thus, each calibration data does not need to be stored in different unit storage spaces, and the method provided in the embodiments of the present application can improve the storage resource utilization rate of the unit storage space while realizing the acquisition of the target calibration data.

[0097] Exemplarily, writing each bit included in the target calibration data and a first quantity of first padding bits into the first spare storage space includes: writing the i-th bit included in the target calibration data into the i-th bit position of the first spare storage space, and writing the first quantity of first padding bits into the remaining bit positions of the first spare storage space; where i is used to represent the serial 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 writing the any one bit into the corresponding bit position in the first spare storage space, the corresponding bit position may be cleared first, and then the any one bit is written into the cleared bit position. The principle is the same when writing any one of the first padding bits into the corresponding bit position in the first spare storage space, and details are not described herein again.

[0098] In the embodiments of the present application, reading each bit included in the target calibration data and writing each bit included in the target calibration data into the first spare storage space can be executed alternately. That is to say, after reading the i-th bit included in the target calibration data, the i-th bit can be written into the first spare storage space, then the (i + 1)-th bit included in the target calibration data is read, and the (i + 1)-th bit is written into the first spare storage space. By alternately executing the operations of reading bits and writing bits, the read bits can be directly written into the first spare storage space, without occupying other storage spaces outside the first spare storage space to store the already read bits, nor transferring the already read bits from other storage spaces to the first spare storage space. The way of alternately executing reading bits and writing bits can reduce the occupation of storage space and shorten the time from starting to read each bit to writing each bit into the first spare storage space.

[0099] Taking one byte in a continuous plurality of bytes as the unit storage space as an example, the embodiments of the present application provide a code logic for writing each bit of the target calibration data into the first spare storage space, and the code logic can be as follows:

[0100]

[0101]

[0102] In this code logic, the starting read address is obtained according to the starting address of the unit storage space and the initial offset value corresponding to the target calibration data. The starting read address is represented by ori_offset, and the number of bits included in the target calibration data is represented by target_cnt. The second-byte destination index is used to indicate the bit position of the bits included in the target calibration data in the first spare storage space, and the bit sequence number is represented by bit_dst_cnt. Thus, in combination with this code logic, the i-th bit included in the target calibration data can be written into the i-th bit position in the first spare storage space by performing the following operations (21) to (24) on the i-th bit.

[0103] Operation (21), based on ori_offset, obtain the storage address of the i-th bit, and the storage address is represented by the second-byte source index and the second-bit source index.

[0104] Operation (22), obtain the second-byte destination index of the i-th bit.

[0105] Operation (23), clear the bit position of the i-th bit in the first spare storage space according to the second-byte destination index.

[0106] Operation (24), based on the second-byte source index and the second-bit source index, reads the i-th bit from the storage address of the i-th bit, and writes the i-th bit to the cleared bit position.

[0107] After performing the above operations (21) to (24) on the i-th bit, similar operations to the above operations (21) to (24) can be performed on the i + 1-th bit until all bits of the target calibration data are written to the corresponding bit positions.

[0108] In the method provided by the embodiments of the present application, multiple calibration data of the WiFi chip to be calibrated are stored in a unit storage space. When it is necessary to use the target calibration data to calibrate the working parameters of the WiFi chip to be calibrated, the initial offset and the number of bits corresponding to the target calibration data can be obtained first. According to the initial offset and the number of bits, each bit included in the target calibration data is read from the unit storage space, so that the target calibration data can be obtained by parsing and processing the read bits.

[0109] Since the number of bits included in the target calibration data can be any value less than the number of bits corresponding to the unit storage space, this method is applicable to different situations of the number of bits included in the calibration data. Moreover, since the unit storage space can store multiple calibration data, the storage resource utilization rate of the unit storage space is relatively high.
