    • 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
    • 要解决的问题:提供一种经受瞬态误差约束的电子系统的处理方法,以检测瞬态误差的方面,并纠正它们。 解决方案:在遭受瞬态误差约束的电子系统的处理过程中,存在于单个物理信道中的两个虚拟通道在预定的实时周期内被多路复用(从虚拟通道的每次执行创建的数据 存储,以便在使用前进行投票)。 如果检测到错误,则处理中的实时循环被禁止,并且当重新加载的上下文开始时,重新加载没有异常的上下文,以便执行包括下一个循环的虚拟执行的重新启动。 本发明还涉及用于监视存储器访问的设备。 版权所有(C)2010,JPO&INPIT
