Abstract: The invention relates to a communication method and its system between interconnected die and DSP/FPGA. The method includes multiple data interfaces. Each data interface is provided with a different protocol conversion module, wherein the data interface communication includes data input conversion and data output conversion; wherein during input conversion, the external data is converted into a unified data protocol format by protocol conversion module, which is transmitted to the network on die for unified data transmission; wherein during output conversion, the internal data is converted into different data protocol formats by protocol conversion module, and then enters different data interfaces and is transmitted to the DSP/FPGA. This method allows each device and component to be connected to the multi-die system in any form, which improves the flexibility of the system.

Abstract: The invention discloses connections among dies, in particular to interconnected dies, comprising: protocol conversion circuits, external interconnected interfaces and networks on die. The protocol conversion circuits comprise multiple protocol conversion modules which are used to communicate with various standard mainstream protocol interfaces. The external interconnected interfaces comprise several synchronization controllers which are used to communicate with other interconnected dies. The networks on die comprise transmission buses and routers which are used to transmit data packets from the interfaces or other interconnected dies. At the same time, the synchronization controllers and the protocol conversion modules are respectively connected with boundary nodes of the networks on die.

Abstract: The present disclosure discloses a vehicle diagnosis method including: sending a login request of a user to a server; returning vehicle type selection data after the server has verified an authenticity of the user successfully; displaying a vehicle type selection interface related to the vehicle type selection data and sending a corresponding vehicle type data to the server based on a vehicle type selected by the user on the vehicle type selection interface via the user equipment; sending corresponding vehicle type data to the server; returning a vehicle diagnosis interface related to the vehicle type data by the server; controlling relevant vehicle terminal to perform corresponding vehicle diagnosis operation by the server when the server receives a vehicle diagnosis instruction as input by the user on the vehicle diagnosis interface; afterwards, displaying vehicle diagnosis operation result fed back by the vehicle terminal through the user equipment.
