Abstract

The invention relates to a multi-core processing system, an inter-core communication method thereof and a storage medium, and the method comprises the following steps: reading a message correspondingto a sending core in a shared memory, and analyzing the message to obtain a source address and a data length of to-be-transmitted data; performing storage space allocation according to the data lengthto obtain a destination address of the to-be-transmitted data; and according to the source address, the data length and the destination address, transmitting the to-be-transmitted data from the storage space corresponding to the source address to the storage space corresponding to the destination address in a DMA mode. The method can improve the CPU efficiency and reduce the access delay.

Description

technical field [0001] The present application relates to the technical field of integrated circuits, in particular to a multi-core processing system, an inter-core communication method, and a storage medium. Background technique [0002] With the integration of different types of CPU (Central Processing Unit, central processing unit) by SOC (System On Chip, system on chip), inter-core communication becomes more and more complex and diverse, especially the requirements for transmission performance of large amount of data are becoming more and more high. The current inter-core communication method has the problem of high application access delay. Contents of the invention [0003] Based on this, it is necessary to provide a multi-core processing system, an inter-core communication method, and a storage medium capable of reducing application program access delays to address the above technical problems. [0004] In a first aspect, a method for inter-core communication of a...
