Inter-core communication method, processor and multi-processor communication system

A multi-processor communication system comprising:

• a first processor including:
• a first inter-core processing circuit;
• and
• a first cross-processor communication agent circuit;
• and
• a second processor including:
• a second inter-core processing circuit;
• and
• a second cross-processor communication agent circuit,
• wherein:
• the first inter-core processing circuit is configured to:
• receive an inter-core message sent by a first core of the first processor, the inter-core message indicating a target core;
• determine, according to the inter-core message, that the target core is a second core of the second processor;
• and
• send the inter-core message to the first cross-processor communication agent circuit;
• and
• the first cross-processor communication agent circuit is configured to send the inter-core message to the second cross-processor communication agent circuit;
• the second cross-processor communication agent circuit is configured to send the inter-core message to the second inter-core processing circuit;
• and
• the second inter-core processing circuit is configured to send the inter-core message to the second core;
• wherein:
• the first cross-processor communication agent circuit is arranged at the first core;
• the second cross-processor communication agent circuit is arranged at the second core;
• the first inter-core processing circuit is arranged at the first core;
• and/or
• the second inter-core processing circuit is arranged at the second core.
