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.
