Problems solved by technology

[0002] Traditional hardware description languages ​​(such as: VHDL) are not suitable for directly describing the program logic and execution flow of high-level programming languages. Therefore, when designing hardware description conditions, they cannot directly correspond to the processes designed by high-level programming languages. Therefore, In addition, traditional high-level programming languages ​​cannot be directly converted into hardware description languages ​​(such as: VHDL), which also causes inconvenience in design, and because there are many types of high-level programming languages, such as: Java, C, or C++, etc., so although the functions of the designed programs are the same, the complete execution process cannot be unified due to the characteristics of the programming language, causing troubles in the design of hardware components. Therefore, the existing methods cannot directly integrate high-level programming languages Converted into a hardware description language, so it is necessary to improve

example 1

[0063] Example 1 For Statement conversion:

[0064] Its syntax is as follows, please refer to Figure 4a Shown:

[0065] for([ForInit()]; [Expression()]; [ForUpdate()])Statement()

[0066] It is described as follows with a Java source code:

[0067]

[0068] The above Java source code conversion process is as follows:

[0069] step1: Parsing "for" and "(";

[0070] step2: Analyze (For Init()), draw the node represented by circle 1 in the figure, set In-Node and Out-Node, and connect online;

[0071] step3: parse ";";

[0072] step4: Analyze (Expression()) execute the newly added java program processConditionExpression(), generate Decode Node (D), and generate the wiring below the Decode node and the edge label on it

[0073] Completely draw the subgraph (a collection of nodes) represented by circle 2 in the figure, and set the In-Node and Out-Node;

[0074] step5: parse ";";

[0075] step6: Analyze (ForUpdate), draw the node represented by circle 3 in the figure;

...

example 2

[0084] Example 2 Conversion of While Statement:

[0085] Its syntax is as follows,

[0086] while(Expression())Statement()

[0087] Here is a Java source code conversion description as follows:

[0088]

[0089] The conversion process is as follows, please refer to Figure 4b Shown:

[0090] step1: Analyze "while" and "(";

[0091] Step2: Analyze Expression(), and generate circle 1 in the figure, and obtain the Out-Node of the sub-graph;

[0092] Step3: Execute the newly added java program processConditionExpression(), generate Decode Node (D), and generate the wiring below the Decode node and the edge label on it, and completely draw the subgraph represented by circle 2 in the figure (node set), set In-Node and Out-Node;

[0093] step4: connect the Out-Node of circle 2 (Expression()) and the In-Node of circle 1 (Statement());

[0094] step5: generate a Merge node, as shown in circle 3;

[0095] step6: connect the Out-Node of circle 1 (Statement()) to the Merge node...

example 3

[0098] Example 3 Conversion of Do Statement:

[0099] Its syntax is as follows,

[0100] do Statement() while(Expression());

[0101] Here is a Java source code conversion description as follows:

[0102]

[0103] The conversion process is as follows, please refer to Figure 4c Shown:

[0104] step1: parse "do";

[0105] Step2: Parse Statement() to generate as circle 1 in the figure, and obtain its Out-Node;

[0106] step3: Analyze "while" and "(";

[0107] Step4: Execute the newly added java program processConditionExpression(), generate DecodeNode(D), and generate the wiring below the Decode node and the edge label on it, and completely draw the subgraph represented by circle 2 in the figure (node's Collection), set In-Node and Out-Node;

[0108] step5: analyze ")" and ";";

[0109] step6: Connect the Out-Node of circle 1 (Expression()) and the In-Node of circle 2 (Statement());

[0110] step7: Generate a Merge node, as shown in circle 3;

[0111] step7: connect...

Abstract

A method for converting high order program language to be active diagram includes adding new conversion rule in compiler and revising specification of active diagram in UML program language to convert program original code to be corresponding active diagram for presenting program logic and execution process flow of original code in visible mode.

Description

technical field [0001] The invention relates to a method for automatically converting a high-level programming language into an activity diagram, especially a method for converting the source code of a high-level program into a corresponding activity diagram, and visually presenting the program logic and execution of the source code process. Background technique [0002] Traditional hardware description languages ​​(such as: VHDL) are not suitable for directly describing the program logic and execution flow of high-level programming languages. Therefore, when designing hardware description conditions, they cannot directly correspond to the processes designed by high-level programming languages. Therefore, In addition, traditional high-level programming languages ​​cannot be directly converted into hardware description languages ​​(such as: VHDL), which also causes inconvenience in design, and because there are many types of high-level programming languages, such as: Java, C...
