Abstract (en)

[origin: WO2022063720A1] The present description concerns an embedded electronic system or a method implemented by such a system including: at least one volatile memory (RAM); at least one low-level operating system managing the allocation of areas of the volatile memory to a plurality of high-level operating systems, each including one or a plurality of applications (App20, App21), wherein data of execution of one or a plurality of tasks of said first application (App20) are partly transferred by the low-level operating system from said volatile memory to a non-volatile memory (WM) when the execution of said task of the first application is interrupted by the execution of at least one task of a second application (App21).
