Abstract

The present application discloses a file sharing method, system, storage medium and chip applied to a multi-domain SOC, related to technical field of chips. When a first process in a first domain shares a target file to a second process in a second domain, it acquires a file handle of the target file for identifying the target file; it maps its own first file structure for operating the target file to a shared memory to obtain a first mapping address; the second process creates a second file structure, acquires the first mapping address, points the second file structure to the first mapping address and operates the target file according to the file handle through the second file structure. This application eliminates multiple links and copies during the cross-domain file sharing, which not only saves resources, but improves the transmission rate and realizes the highspeed transmission of big data.
