For example, when generating a code generation rule corresponding to a business to be processed according to multiple abstraction parameters, the multiple abstraction parameters may be processed first to determine the abstraction parameter required by the code generation rule, that is, the target abstraction parameter. For example, if the description file is a table, the abstraction parameter at the header position of the table among the plurality of abstraction parameters is determined as the target abstraction parameter; and according to the plurality of target abstraction parameters, the business to be processed is generated. Corresponding code generation rules. For example, if the description file is text, multiple target abstraction parameters can be obtained by reading the initial position of the text, which can be set according to actual needs.

According to the above-mentioned embodiment, when the abstraction parameter is the specific information and quantity of the state information, condition information and execution action information contained in the code corresponding to the business to be processed, correspondingly, the code generation rule is the state information, condition information And the number information of the execution action information.

Wherein, the structure of the target code corresponding to the service to be processed may include a duplicate part of the generated target code, or may include other parts, which are not limited in this embodiment of the present application.

In order to facilitate understanding of the code generation method provided by the embodiments of the present application, the following will take the specific application of the method in practice as an example to describe the technical solutions provided by the embodiments of the present application in detail. Referring to FIG. 3 , FIG. 3 is a schematic flowchart of another code generation method provided by an embodiment of the present application.

The scheduler can be used in the generation of the code, which can ensure that the division of labor of each software and/or hardware device in the code generation process is clear, thereby improving the efficiency of code generation. The scheduling definition in Figure 3 is that when the code generation instruction is received, the type of the service to be processed and the identifier of the service to be processed can be determined, and the state information, condition information and Execute action information. It is assumed that the state corresponding to the business to be processed is represented by S, the condition is represented by C, and the execution action is represented by A.

Illustratively, the state S may include an initialization state S0 and a plurality of operating states S1 to Sn, the condition C may be a state transition condition between each state S, and Cx_y represents a transition condition from the state Sx to the state Sy, for example, C1_2 Indicates the transition condition from state S1 to state S2. Among them, each state S includes three sub-states, which are an initialization sub-state en, a running sub-state du and an exit sub-state ex. The execution action A is the action executed by each sub-state, wherein the action of executing the initialization sub-state en can be Aen_1 to Aen_n, which means that the actions of initializing sub-state 1 to sub-state n are executed in sequence; the action of executing the running sub-state du can be Adu_1 ～Adu_n means that the actions of running sub-state 1 to sub-state n are executed in sequence; the actions of executing and exiting sub-state ex can be Aex_1-Aex_n, which means that the actions of exiting sub-state 1 to sub-state n are sequentially executed.

It can be understood that the above state jump conditions are corresponding conditions in the actual code, and the execution actions are function interfaces provided by the basic software layer. The relationship between states, conditions, and execution actions can be referred to as shown in FIG. 4 , which is a schematic flowchart of code running provided by an embodiment of the present application.

As shown in FIG. 4 , during the running of the code, the actions of the initialization sub-state en in the initialization state S0 are sequentially performed, that is, the actions of the initialization sub-state 1 to the initialization sub-state n are sequentially performed. After the initialization of the sub-states is completed, the actions of the running sub-state du in the initialization state S0 are executed in sequence, that is, the actions of the running sub-state 1 to the running sub-state n are executed in sequence, and the action of running the n sub-states in sequence is performed cyclically , until the jump condition C=C0_x is received. After receiving the jump condition, stop executing the actions of the running sub-states in the initialization state S0 in sequence, and change to execute the actions of exiting the sub-state ex in the initialization state S0 in sequence, that is, executing the exit sub-state 1 to the exit sub-state n in sequence Actions. The jumping condition may be jumping from the initialization state S0 to the state S1, or jumping from the initialization state S0 to the state S1, and the embodiment of the present application does not make any limitation on the specific jumping condition.

After executing the exit actions of the multiple sub-states in the initialization state S0, the state jumps are performed according to specific jump conditions. If the jump condition is C=C0_1, jump from the initialization state S0 to the state S1, run according to the code running mode in the state S1, and jump from the state S1 to the state according to the received jump condition C=C1_2 S2, run according to the code running mode in state S2. If the jump condition is C=C0_2, jump from the initialization state S0 to the state S2, run according to the code running mode in the state S2, and jump from the state S2 to the state according to the received jump condition C=C2_1 S1, run according to the code running mode in state S1. As shown in FIG. 3 , the code running modes in the state S1 and the state S2 are the same as the code running modes in the above-mentioned initialization state S0 , which are not repeated in this embodiment of the present application.

The jump conditions shown in FIG. 4 may be jumped at the same time, or may be jumped according to a certain time sequence, which is not limited in this embodiment of the present application.

As shown in FIG. 3 , after the scheduling definition is performed, a scheduling description file can be established, that is, a description file corresponding to the service to be processed is obtained according to the above analysis result of the service to be processed. The scheduling description file can be referred to as shown in Table 1 below. Table 1 is a scheduler state table, which includes the number of states in which code is generated, initialization state actions and their corresponding numbers, and execution state actions and their corresponding numbers.

Table 1

Table 1 includes a plurality of abstraction parameters and parameter values corresponding to each abstraction parameter, wherein the table header in Table 1 is divided into a plurality of abstraction parameters, namely state identifier, state number, initialization action identifier, initialization action 1, Initialize action 2, execute action flag, execute action 1, and execute action 2. Each parameter value corresponding to the abstraction parameter is the value of the column where each abstraction parameter is located. For example, the parameter values corresponding to the state number are 0, 1, and 2.

In addition, the scheduling description file also includes a scheduler state transition table, as shown in Table 2 below.

Table 2

Table 2 also includes multiple abstraction parameters and parameter values corresponding to each abstraction parameter, wherein the abstraction parameter is the header part of Table 2, that is, the abstraction parameter is the state jump identifier, current state, target state, jump state Transition condition, exit state action flag, exit state action 1, and exit state action 2. The parameter value is the value of the column where each abstraction is located. For example, the parameter value corresponding to the jump condition of the abstraction parameter is C==C0_1, C==C0_2, C==C1_2, C==C1_0, C==C2_0 and C ==C2_1.

Determine the target abstraction parameters according to Table 1 and Table 2, wherein the target abstraction parameters are state number, initialization action 1, initialization action 2, execution action 1, execution action 2, current state, target state, jump condition, exit state Action 1 and exit status action 2 generate corresponding code generation rules according to the target abstraction parameters.

As an example, to further improve the generated code generation rules, in addition to the abstraction parameters shown in Table 1 and Table 2 and the parameter values corresponding to each abstraction parameter, it is also necessary to set the parameters of the scheduler, which can be done by The parameters in the following Table 3 set the parameters of the scheduler, and Table 3 is the scheduler design table.

table 3

scheduler name number of states state variable name APPSc 3 APPScStep

According to the parameters in Table 3, it can be seen that the code generation method of the embodiment of the present application can be implemented by using a state machine, and the number of state machines is consistent with the number of states in Table 3. The transition conditions and the execution actions of each state are consistent with the parameter values corresponding to the abstracted parameters in Table 1 and Table 2. Among them, according to the state variable names in Table 3, it can be known that the state machine in the embodiment of the present application is in the form of switch...case....

It can be understood that the generated code generation rules can be updated and improved according to the parameters of the scheduler shown in Table 3 to obtain new code generation rules. For example, when updating the code generation rule, other parameters of the generated code can also be set. For example, the generated object code contains a .c and a .h file, and the generated file names are xxx.c and xxx. h, where xxx is the scheduling name; and the type.h and util.h header file references need to be added to xxx.h, so that the corresponding data type of the embedded chip is consistent with the system definition; the target code can be an independent function, The function name can be in the form of void xxx_step(void), and the function needs to be marked in xxx.h. This embodiment of the present application only uses the above parameters as an example to update the generated code generation rule, which does not mean that the embodiment of the present application is limited to this.

As shown in Figure 3, after generating the new code generation rule, write the corresponding code generation tool according to the new code generation rule, and import the scheduling description files shown in Table 1 and Table 2 into the code generation tool, The code generation tool can automatically generate code by reading the parameter value corresponding to the target abstraction parameter, that is, generate the target code corresponding to the business to be processed.
