Claim 6:
7. The communication method of an interconnected die and an MPU according to claim 3, wherein the interrupt transmission comprises an interrupt transmission between a first MPU (master) and a second MPU (master) and an interrupt transmission between the MPU (master) and the slave device;
the interrupt transmission between a first MPU and a second MPU comprises the following steps: the first MPU writes interrupt information to a fixed interrupt address preset in the address space of the first MPU through the data interface, and the interrupt interface packs the interrupt information into an interrupt event data packet and sends it to the interconnected die; the second MPU receives the interrupt event data packet through the interrupt interface and unpacks, and translates it into an interrupt signal;
when the interrupt is transferred from the master device to the slave device, the interrupt interface of the slave device collects the interrupt information from the slave device and encodes and packs it into an interrupt event data packet and sends it to the interconnected die; the interrupt interface of the MPU receives the interrupt event data packet and unpacks, and translates it into an interrupt signal.
