These terms are only used to distinguish one device from another of the same type. For example, a first device could also be termed a second device, and, similarly, a second device could also be termed a first device, without departing from the scope of the present invention. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.
The information display method of the embodiment of the invention can be applied to any occasion needing to carry out equipment debugging. For example, the method can be applied to development, test or maintenance of equipment, and registers in the equipment need to be debugged to analyze, locate and solve equipment problems.
The following describes the information display method according to the embodiment of the present invention in more detail, but the method is not limited thereto.
In one embodiment, referring to fig. 1, an information display method is applied to an electronic device, and the method includes the steps of:
s100: acquiring register data according to a register address of a register to be debugged, wherein the register data comprises at least one bit of register value;
S200: according to the set attribute-register value analysis rule corresponding to the register address, analyzing register values corresponding to N attributes from the register data; n is greater than or equal to 1;
s300: and judging whether the register value corresponding to each attribute meets the attribute condition corresponding to the attribute according to each attribute, and displaying a judging result.
The execution subject of the information display method of the embodiment of the invention is electronic equipment. The electronic device may be a debug enabled device, such as a computer device. The electronic device may implement the above steps S100-S300 by running a debugging program stored in the device.
The electronic device may debug a register on the target device. The target device is a device where the problem is currently required to be determined through debugging, and can be an embedded device, and the specific device type is not limited. The electronic device and the target device may be connected through a serial port or a communication interface such as an ethernet interface. The specific connection mode of the electronic device and the target device is not limited, as long as the communication between the electronic device and the target device can be realized.
Referring to fig. 2, the electronic device 500 may include a processor 510, a non-volatile memory 520, a communication interface 530, a memory 540, etc., and the debugging program may be permanently stored in the non-volatile memory, and when the execution is required, the processor 510 reads the debugging program into the memory 540 and invokes the debugging program in the memory 540 to implement steps S100-S300. The communication interface 530 of the electronic device 500 is connected to the communication interface 410 of the target device 400, and the processor 510 communicates with the target device 400 via the connection between the communication interface 530 and the communication interface 410, such as for example, transmission of instructions or register data.
In step S100, register data is obtained according to a register address of a register to be debugged, wherein the register data includes at least one register value.
The register to be debugged may be any register in the target device, as may be desired. The electronic device obtaining register data according to a register address of a register to be debugged may include: the register address of the register to be debugged is sent to the target equipment, so that the target equipment reads the register data from the register corresponding to the received register address and sends the register data to the electronic equipment; register data sent from the target device is received.
With continued reference to fig. 2, the operating system of the target device 400 may be divided into an application layer and a system layer according to functions, the application layer being responsible for interaction with the outside world, and the system layer being responsible for interaction with the underlying hardware. The application layer of the target device 400 may receive the register address sent by the electronic device 500 through the communication interface 410, find a register corresponding to the register address through the system layer, read the register data from the register, and then send the register data to the electronic device 500 through the communication interface 410 by the application layer.
The register data acquired by the electronic device may be binary data, hexadecimal data, or the like, depending on the target device. The number of register values contained in the register data depends on the number of bits of the register data, which depends on the number of bits of the register data and the number of bits of the register. The registers may be 32-bit registers, 64-bit registers, etc., and the specific number of bits is not limited.
For example, in the case where the number of bits of the register to be debugged is 32 bits, if the register data is binary data, 32 register values are included in the register data, and if the register data is hexadecimal data, 8 register values are included in the register data.
The register address may be entered or selected by a user, or may be determined by the electronic device in a certain address determination manner, and the specific manner is not limited.
Taking the register address as an example of input by a user, the user may input one or more register addresses at a time, for example, may input one register address interval at a time, and the electronic device needs to obtain the register data stored in the register corresponding to each register address in the register address interval.
Referring to the display interface shown in fig. 3, a user may input a register address interval 0x10000000-0x100000ff in a register address input area Z11 of the electronic device, and the electronic device may acquire register data according to each register address in the register address interval.
Optionally, the electronic device may also display the register address and the register data in the register address-data display area Z12. Fig. 3 only shows three register addresses in the register address interval 0x10000000-0x100000ff and register data on corresponding registers, respectively: register address 0x10000000 and register data c0b12123, register address 0x10000004 and register data 00000001, and register address 0x10000008 and register data 00000001.
In step S200, according to the set attribute-register value analysis rule corresponding to the register address, analyzing the register values corresponding to the N attributes from the register data; n is 1 or more.
The electronic device may be preset with a register rule base, where the register rule base includes different attribute-register value analysis rules, which are respectively used to analyze register data of different registers. The attributes in different rules may be the same or different, and the number of the attributes may be the same or different, which may be determined according to the attributes to be described in the corresponding register data.
A register rule base may be set for each type of device, avoiding the problem that when the register addresses of different types of devices are the same (typically the register data are different), it is impossible to distinguish which device's registers are. Of course, a register rule base may be provided for a plurality of types of devices as long as different devices can be distinguished.
The attribute-register value resolution rule corresponding to the register address, such as the attribute-register value resolution rule containing the register address, may be obtained from a register rule base according to the register address of the register to be debugged.
The register rule base may be presented in the form of a document, or a table, but may be in other forms, and the specific form is not limited. Taking a register rule base as a table as an example, an item where a register address is located can be found from the register rule base, and the found item is used as an attribute-register value analysis rule corresponding to the register address.
Of course, how to determine the attribute-register value analysis rule corresponding to the register address is not limited thereto, and may be determined as long as the corresponding relationship between the register address and the attribute-register value analysis rule is established.
The register data contains at least one register value, one register value may be used to describe an attribute, or a plurality of register values may be used to describe an attribute. For example, year may be described by register values at bits 1-12 in the register data and version number may be described by register values at bits 13-20 in the register data, although this is merely an example of an attribute.
The attribute-register value resolution rules may include: n attributes. Correspondingly, according to the attribute-register value analysis rule, the register values corresponding to the N attributes can be analyzed from the register data. Continuing with the year and version number as examples, assuming that the attribute-register value parsing rule includes two attributes, namely a year and a version number, then the register value corresponding to the year, for example, the register value on bits 1-12, and the register value corresponding to the version number, for example, the register value on bits 13-20, are to be parsed from the register data.
Of course, the attribute-register value analysis rule may also include other information, such as a standard attribute value (preset) corresponding to the attribute, and the like, which is not particularly limited thereto.
Optionally, before resolving the register values corresponding to the N attributes from the register data, the method further includes:
And when the current system of the register data is different from the target system, the target system is the system supported by the attribute-register value analysis rule, and the register data is converted from the current system to the target system.
Correspondingly, the register values corresponding to the N attributes can be resolved from the register data of the target system.
Optionally, the target system is binary. Assuming that the acquired register data is hexadecimal, it is necessary to convert the register data from hexadecimal to binary. After the binary conversion, the number of register values of the register data also changes correspondingly.
Of course, the acquired register data may be binary, octal, decimal, or the like. The target device can directly send the read register data to the electronic device; or the target device may perform certain binary conversion on the read register data and send the register data to the electronic device.
For example, referring to fig. 4, the binary register data of 1100 0000 1011 0001 0010 0001 0010 0011 is obtained by converting the binary of c0b12123 from hexadecimal to binary according to the register data of c0b12123 acquired by the register address 0x 10000000. The binary register data is respectively 1 st to 32 nd register values from right to left, and the register values are represented by bits [0-31 ]. That is, an 8-bit hexadecimal register data is converted into a 32-bit binary register data.
By combining the year and the version number, the register value corresponding to the year is resolved from the register data according to the attribute-register value resolving rule, for example, the register value on bit [0-11] is 0001 0010 0011; the register value corresponding to the version number is resolved according to the attribute-register value resolution rule, for example, the register value on bits 13-20, for example, the register value on bits 12-19 is 0001 0010.
Of course, when the current system of the register data is the same as the target system, the electronic device may not need to perform a number system conversion on the register data, and parse the register values corresponding to the N attributes from the acquired register data.
In step S300, for each attribute, it is determined whether the register value corresponding to the attribute satisfies the attribute condition corresponding to the attribute, and the determination result is displayed.
The attribute conditions corresponding to the N attributes are preset. Whether the register value corresponding to each attribute meets the attribute condition corresponding to the attribute can be judged, and the judging results are displayed on the electronic equipment.
For each attribute, the manner of determining whether the register value corresponding to the attribute satisfies the attribute condition corresponding to the attribute may be, for example, the following modes:
First, the attribute-register value analysis rule may include N standard register values corresponding to the attributes, and for each attribute, it may be determined whether the register value corresponding to the attribute is the same as the standard register value corresponding to the attribute, if so, the standard register value is satisfied, or else, the standard register value is not satisfied.
Second, the attribute-register value analysis rule may include N standard attribute values corresponding to the attributes, and for each attribute, a current attribute value corresponding to the attribute may be determined according to the register value corresponding to the attribute, and whether the current attribute value corresponding to the attribute is the same as the standard attribute value is determined, if so, the standard attribute value is satisfied, or else the standard attribute value is not satisfied.
Of course, the above two modes are merely examples and are not limiting. The second mode will be described in detail later, and will not be explained here.
After the judgment result of the register value corresponding to each attribute is displayed, a user can determine whether the register value corresponding to each attribute is correct or not according to the displayed judgment result, so that when the register value is wrong, the problem generated by the target equipment can be analyzed and positioned.
For convenience of further operation, other information such as register address, register data, etc. may be displayed together with the judgment result. With continued reference to fig. 3, on the register value analysis display area Z13, each register address, register data, and judgment result in the register section input by the user may be displayed in the form of a list.
In the embodiment of the invention, when a register corresponding to a certain register address is required to be debugged, after the register data is acquired according to the register address, the register values corresponding to N attributes can be analyzed from the register data according to the attribute-register value analysis rule corresponding to the register address, whether the register value corresponding to each attribute meets the corresponding attribute condition is judged, and the judgment result is displayed, so that a debugger can directly determine whether the register data is correct or not and which register values in the register data are wrong when the judgment result is wrong, the analysis of the register data can be rapidly completed, and even a new hand without debugging experience can easily perform the debugging, and the debugging efficiency is improved.
In one embodiment, the above method flow may be performed by the information display apparatus 100, and as shown in fig. 5, the information display apparatus 100 may include 3 modules: a register data acquisition module 101, a register value analysis module 102, and a judgment and display module 103. The register data obtaining module 101 is configured to execute the step S100, the register value analyzing module 102 is configured to execute the step S200, and the determining and displaying module 103 is configured to execute the step S300.
In one embodiment, the attribute-register value resolution rule includes: data bit indication information corresponding to the attribute;
in step S200, the parsing the register values corresponding to the N attributes from the register data may include the following steps:
s201: and for each attribute in the attribute-register value analysis rule, searching a register value on a data bit corresponding to the data bit indication information from the register data, and determining the searched register value as a register value corresponding to the attribute.
The data bit indication information may indicate which bits of register values in the register data the attribute corresponds to. The data bit indication information corresponding to each attribute is different, and the number of data bits corresponding to the data bit indication information can be the same or different. For example, the number of data bits corresponding to one data bit indicating information is 10, and the number of data bits corresponding to the other data bit indicating information is 12, and the present invention is not limited thereto, and actually may be selected between the total number of bits of 1-register data.
For each attribute in the attribute-register value analysis rule, a register value on a data bit corresponding to the data bit indication information is searched from the register data, and the searched register value is determined to be the register value corresponding to the attribute.
Continuing to take the attribute as year as an example, referring to fig. 4, the data bit corresponding to the data bit indication information corresponding to the year is bit [0-11] which is bit 1-12, and the register value on bit [0-11] is 0001 0010 0011 determined from 1100 0000 1011 0001 0010 0001 0010 0011, and 0001 0010 0011 is determined as the register value corresponding to the year.
In one embodiment, the attribute-register value resolution rule includes: register value processing mode and standard attribute value corresponding to the attribute;
in step S300, the determining whether the register value corresponding to the attribute meets the attribute condition corresponding to the attribute may include the following steps:
s301: calculating the register value corresponding to the attribute according to the register value processing mode corresponding to the attribute to obtain the current attribute value corresponding to the attribute;
s302: and comparing whether the current attribute value is consistent with the standard attribute value corresponding to the attribute, if so, determining that the register value corresponding to the attribute meets the attribute condition corresponding to the attribute, and if not, determining that the register value corresponding to the attribute does not meet the attribute condition corresponding to the attribute.
In step S301, a current attribute value corresponding to the attribute is obtained by calculating a register value corresponding to the attribute according to a register value processing manner corresponding to the attribute.
The register value processing manner may include, for example: mathematical operation, logical operation, condition judgment, binary conversion and other processing modes. The logical operations may include, for example: "&" (logical AND), "||" (logical OR), etc. Mathematical operations may include, for example: "+" (addition), "-" (subtraction), "x" (multiplication), "/" (division), etc. The condition judgment includes, for example: "= =" (equal to), "+|! = "(not equal to). The binary conversion may include binary to decimal, binary to octal, and so on.
When the logical operation and the mathematical operation are performed on the numerical value, the register value corresponding to the attribute can be split into two parts for operation, for example, 110011 can be split into 110 parts and 011 parts for operation; or the register value corresponding to the attribute may be operated with a preset register value, for example 110011 may be operated with a preset 111111. When the value is subjected to condition judgment, the register value corresponding to the attribute can be compared with a preset register value, for example, whether the register value corresponding to the attribute is 1 is judged.
Of course, the register value processing method may be a combination of at least two of the above processing methods, and the specific processing method is not limited.
And processing the register value corresponding to the attribute according to a register value processing mode corresponding to the attribute in the attribute-register value analysis rule to obtain the current attribute value corresponding to the attribute.
For example, referring to fig. 4 and 6, in the attribute-register value parsing rule corresponding to the register address 0x10000000, there are two attributes, i.e., version number and year, respectively. The data bit corresponding to the version number indicates that the data bit corresponding to the information is bit [0-11] which is bit 1-12, the register value on bit [0-11] in the register data is 0001 0010 0011, the register value is processed in a way such as binary to decimal, the binary of 0001 0010 0011 is converted into decimal to obtain 291, namely the current attribute value corresponding to the version number is 291. The data bit corresponding to the data bit indication information of the year is 13-20 bits, namely bits [12-19], the register value of the register data on the bits [12-19] is 0001 0010, and the current attribute value corresponding to the year is 18 when the binary system of 0001 0010 is converted into decimal system to obtain 18.
In step S302, whether the current attribute value is consistent with the standard attribute value corresponding to the attribute is compared, if yes, it is determined that the register value corresponding to the attribute meets the attribute condition corresponding to the attribute, and if no, it is determined that the register value corresponding to the attribute does not meet the attribute condition corresponding to the attribute.
The standard attribute value is the correct attribute value for the attribute, which can be determined at a pre-set time. The register value corresponding to the attribute can be determined whether the corresponding attribute condition is satisfied by measuring whether the current attribute value is consistent with the standard attribute value or not with reference to the standard attribute value.
If the current attribute value corresponding to the attribute is consistent with the standard attribute value, the current attribute value is correct, namely the register value corresponding to the attribute in the register data is also correct, and the register value corresponding to the attribute is determined to meet the attribute condition corresponding to the attribute.
If the current attribute value corresponding to the attribute is inconsistent with the standard attribute value, the current attribute value is wrong, namely the register value corresponding to the attribute in the register data is wrong, and the event related to the register in the target device is abnormal, and the register value corresponding to the attribute is determined to not meet the attribute condition corresponding to the attribute.
With continued reference to fig. 4 and 6, for example, in the attribute-register value analysis rule, the attribute condition corresponding to year is bit [12-19] = 19 (i.e. determine whether the current attribute value corresponding to year is equal to 19), 19 is the standard attribute value corresponding to year, and the current attribute value calculated according to the register value on bit [12-19] in the register data is 18, so that the current attribute value corresponding to year is inconsistent with the standard attribute value, it may be determined that the register value corresponding to year does not satisfy the attribute condition corresponding to year.
In another example, in the attribute-register value analysis rule, the attribute condition corresponding to the version number is bit [1-11] = 291 (i.e. whether the current attribute value corresponding to the version number is equal to 291 is determined), 291 is the standard attribute value corresponding to the version number, and the current attribute value calculated according to the register value on bit [1-11] in the register data is 291, so that the current attribute value corresponding to the version number is consistent with the standard attribute value, and it can be determined that the register value corresponding to the version number meets the attribute condition corresponding to the version number.
In one embodiment, in step S300, if the determination result is that the register value corresponding to the attribute does not satisfy the attribute condition corresponding to the attribute, the displaying the determination result includes:
and displaying an abnormal mark, the attribute and a standard attribute value corresponding to the attribute, wherein the abnormal mark indicates that the current attribute value is different from the standard attribute value.
The exception flag indicates that the current attribute value is different from the standard attribute value, so that the exception flag is displayed, a debugger can be prompted that the register value corresponding to the attribute does not meet the attribute condition corresponding to the attribute, so that the debugger can quickly respond, and a solution is taken as soon as possible.
The attribute and the standard attribute value corresponding to the attribute represent the information which should be described by the register value corresponding to the attribute, and if the exception mark is displayed at the same time, a debugger can quickly determine the data bit of the error register value and the correct register value according to the attribute and the standard attribute value.
Optionally, the exception flag, the attribute and the standard attribute value corresponding to the attribute may be displayed, and the current attribute value corresponding to the attribute may be displayed. The current attribute value is the information currently described by the register value corresponding to the attribute, and is provided for a debugger, so that the debugger can analyze the cause of the problem.
For example, referring to fig. 3, in the register value analysis display area Z3 in fig. 3, only one debug record corresponding to a register address is shown, specifically: the register address 0x10000000, the register data c0b12123, and the two determination results are "year 18 (19)", and "version number 291", respectively, wherein "year 18 (19)" indicates: the current attribute value for year is 18 and the standard attribute value for year is 19, so the register value for year does not satisfy the corresponding attribute condition.
Meanwhile, for "year 18 (19)", an abnormality flag may also be displayed. The abnormality flag may be a first color such as a red flag, for example, in the register value resolution display area Z3 of fig. 3, the background color of the cell where "year 18 (19)" is located may be set to red (not shown in fig. 3). Of course, the anomaly marks may also be in other mark forms, such as symbol marks (brackets added to 19 as described above may in fact also be used as anomaly marks), etc.
Alternatively, the attributes may be presented in a language recognizable to the user, such as chinese, english, etc. Attribute values may be presented in numbers, characters, etc., and may be specific to the attribute.
In one embodiment, in step S300, if the register value corresponding to the attribute satisfies the attribute condition corresponding to the attribute as a result of the determination, the displaying the determination result includes:
and displaying a normal mark, the attribute and a standard attribute value corresponding to the attribute, wherein the normal mark indicates that the current attribute value is the same as the standard attribute value.
The normal mark indicates that the current attribute value is the same as the standard attribute value, so that the normal mark is displayed, a debugger can be prompted, the register value corresponding to the attribute meets the attribute condition corresponding to the attribute, so that the debugger can confirm that the register has no abnormal condition and can be distinguished from the abnormal condition.
The attribute and the standard attribute value corresponding to the attribute represent the information which should be described by the register value corresponding to the attribute, if the normal mark is displayed at the same time, the standard attribute value is the information which is described currently by the register value corresponding to the attribute, in this case, the result of displaying the standard attribute value or the current attribute value is the same, and the situation is provided for the debugger, so that the debugger can confirm that the event related to the register is normal.
For example, with continued reference to fig. 3, in the register value resolution display area Z3 of fig. 3, "version number 291" indicates: the current attribute value and the standard attribute value corresponding to the version are the same and are 291, so the register value corresponding to the version number meets the corresponding attribute condition. 291 is both the standard attribute value corresponding to the version number and the current attribute value corresponding to the version number.
Meanwhile, for "version number 291", a normal flag may also be displayed. The abnormality flag may be a second color such as a green flag, for example, in the register value resolution display area Z3 of fig. 3, the background color of the cell where the "version number 291" is located may be set to green (not shown in fig. 3). Of course, the normal mark may be in other mark forms, and may be distinguished from the abnormal mark.
