Claim 2:
3. A communication method of an interconnected die and an MPU, wherein a data transmission is carried out between the interconnected die and the MPU through a data interface, an interrupt transmission is carried out through an interrupt interface, and an MPU debugging is carried out through a debugging interface; the MPU controls data access between slave devices through a DMA control interface; the data interface comprises an SPI interface, a DDR data interface, and a DMA control interface; the debugging interface comprises a JTAG-Core debugging interface;
when the MPU controls the data access between the slave devices through the DMA control interface, by accessing a preset fixed DMA address in the address space of the MPU, it converts the access address space into the DMA register configuration and starts the DMA to complete the corresponding data movement instructions.
