Abstract: PROBLEM TO BE SOLVED: To provide a processing method for an electronic system subjected to transient error constraints, to detect the aspect of transient errors, and to correct them. SOLUTION: In the processing procedure of the electronic system subjected to the transient error constraints, two virtual channels existing in a single physical channel are multiplexed, in time at a predetermined real time cycle (data created from each execution of the virtual channels is stored so as to allow voting before use). If an error is detected, the real-time cycle under processing is inhibited, and a context having no abnormality is reloaded so as to perform restart including virtual execution of the next cycle, when the reloaded context starts. The present invention also concerns a device for monitoring memory accesses. COPYRIGHT: (C)2010,JPO&INPIT
