Multi-domain system data sharing device and implementation method

Abstract

According to the multi-domain system data sharing device and the implementation method, a first control domain system and a second control domain system are started and initialized, and when the first control domain system judges that a data sharing request in the second control domain system is received, if the first control domain system judges that data of the data sharing request is a service command, the first control domain system sends the service command to the second control domain system; if yes, sending the shared data to a second control domain system by adopting IPC mechanism transmission; if the first control domain system judges that the data of the data sharing request is a data packet, shared data is sent to a second control domain system through shared memory transmission, and the second control domain system receives the shared data and distributes the shared data to a target request program. According to the invention, data sharing of a multi-domain system is realized, hardware modules are saved, and the product cost is reduced.
