Embodiment Construction

[0031] With reference to accompanying drawing, further illustrate the present invention:

[0032] A real-time synchronization method between modules based on memory data architecture, comprising the following steps:

[0033] 1) Read the software component model that conforms to the AUTOSAR standard, and generate a directed acyclic graph representing all component models and their aggregation relationships. The nodes of the directed acyclic graph correspond to the component model types one by one, and the directed acyclic graph Directed edges represent aggregation relationships between component models;

[0034] 2), establish a hash table that corresponds to the directed acyclic graph and can quickly find any component model, the keyword (key) of each record in the hash table is the full name of the corresponding component, and the value (value) is the address of the corresponding component and all its immediate predecessors;

[0035] 3) Define the rules for modifying the com...

Abstract

The invention relates to an inter-module real-time synchronization method based on an internal memory data framework, comprising the following steps of: reading a software assembly model in the AUTOSAR (Automotive Open System Architecture) standard to generate a directed acyclic graph; establishing a hash table; defining rules for modifying the assembly model, wherein the modification rule is unique for each modification type; and acquiring model modification information, storing the model modification information in an operation queue, identifying the modification types, and then corresponding the modification types to the modification rules to modify the directed acyclic graph and the hash table according to the modification rules. The invention can make an assembly design tool and a system configuration tool keep consistent and has the advantage of high development efficiency.

Description

technical field [0001] The invention relates to model-driven integrated development environment technology, in particular to a method for efficiently realizing dynamic consistency of model information between tools. technical background [0002] With the development of the automobile industry, the complexity of the function field of the automobile electronic control system is experiencing rapid growth. Although many software vendors have proposed their own solutions, how to make various tools work together better to achieve a real technological breakthrough is still an important topic to be studied in academia and industry. [0003] AUTOSAR (AUTomotive Open System ARchitecture) is an open automotive electronic software architecture jointly launched by famous automobile companies such as BMW and Continental. From a technical point of view, the AUTOSAR organization is committed to improving the cooperation of developers on standards, thereby improving the performance and safe...
