Multi-core fast message communication method based on descriptor shared circular queue

The invention belongs to the field of multi-core processor embedded systems, and particularly relates to a multi-core fast message communication method based on a descriptor shared circular queue. Establishing a shared circular queue in the shared memory area; a plurality of protocols with different numbers are established on the message sending core and the message receiving core, and each protocol is bound with a message queue; the message sending core writes an inter-core message to be sent in the shared circular queue, the inter-core message is attached with a protocol number, and inter-core interruption is sent to the message receiving core; and the message receiving core receives the inter-core interruption, acquires the protocol number from the inter-core message, puts the protocol number into a corresponding message queue, and uploads the protocol number to the application program. According to the method, multi-core message transmission is carried out in a numbering protocol and message queue binding
