Abstract

The invention provides an inter-core interaction method and device of a multi-core system, equipment and a storage medium, and relates to but is not limited to the technical field of computers. The method comprises the steps that a first kernel determines an interaction channel group corresponding to a target kernel according to the target kernel of first interaction data to be transmitted; the target kernel is one of the at least one second kernel, and the second kernels are in one-to-one correspondence with the interaction channel groups; selecting a first interaction channel from a plurality of second interaction channels of the interaction channel group according to the interaction type of the first interaction data; and sending the first interaction data to the first interaction channel, so that the target kernel obtains the first interaction data by monitoring the interaction channel group. The device, the equipment and the storage medium are applied to the interaction method. According to the embodiment of the invention, the interaction operation among multiple cores can be simplified, so that the execution efficiency of threads among the multiple cores is improved.

Description

technical field [0001] The embodiments of the present application relate to but are not limited to the field of computer technologies, and in particular, relate to an inter-core interaction method, device, device, and storage medium of a multi-core system. Background technique [0002] At present, the inter-core interaction technology of the multi-core operating system is usually implemented through shared memory. Therefore, the system implements memory sharing by maintaining a shared memory space, and this space is a critical resource, so a mutex is usually used to protect the critical resource. Assuming that when a processor core tries to interact with some other processor core or some processor cores, it is called the source processor core, and the interacted processor core is called the destination processor core; then the source processor core must Acquire the mutex first, and then post the data to the shared memory. When the data is written, the mutex may be released ...
