Abstract

Embodiments of the present application disclose a data sharing method and apparatus, a device, and a storage medium. The data sharing method is applied to an electronic device. The electronic device comprises a first system and a second system, and the first system and the second system have a communication link. The method comprises: the first system and / or the second system stores shared data in a shared storage area, the shared storage area being used for storing shared data of the first system and the second system; and the first system and / or the second system acquires the shared data from the shared storage area. The number of instances of data transmission between processors of the first system and the second system can be reduced.
