  • Publication number: 20220276306
    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.

  • Publication number: 20220276982
    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.
