Inter-module real-time synchronization method based on internal memory data framework

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.
