Inter-core communication system, method and device for multi-core processor, and storage medium

An inter-core communication method for a multi-core processor, applied to the inter-core communication system for the multi-core processor, wherein the inter-core communication system for the multi-core processor comprises an inter-core communication device connected to a plurality of systems, the plurality of systems comprises a first system and a second system, and the inter-core communication device comprises a memory management module, a queue management module and an interrupt module,

• and wherein the inter-core communication method for the multi-core processor comprises:
• receiving, by the memory management module, a descriptor application instruction sent by a first system, and determining, by the memory management module, a descriptor pointer corresponding to the descriptor application instruction, wherein the first system is configured to store data to be transmitted into memory corresponding to the descriptor pointer;
• after receiving an enqueue application sent by the first system, enqueuing, by the queue management module, the descriptor pointer into a specified queue;
• and
• after the number of times of enqueues corresponding to the specified queue reaches a preset threshold, dequeuing, by the interrupt module, the descriptor pointer in the specified queue through an interrupt service program of a second system, wherein the second system is configured to read data to be transmitted in a memory corresponding to the dequeued descriptor pointer.
