Abstract
(DE)
Die Erfindung betrifft ein sicherheitsrelevantes Computersystem, insbesondere Eisenbahnsicherungssystem, mit mindestens zwei Hardware-Kanälen (A; B), wobei Speicherprüfergebnisse der Kanäle (A; B) mindestens einem Vergleicher (3) zugeführt sind, der bei Ungleichheit der Speicherprüfergebnisse eine Fehlerreaktion (4) auslöst. Um diversitäre, von Compilern (X, Y) erstellte Software-Programme verwenden zu können, werden Speicherprüfergebnisse (XA, YA; XB, YB) der diversitären Software-Programme jedes Kanals (A; B) dem Vergleicher (3) zugeführt, wobei die Speicherprüfergebnisse (XA; XB) des ersten Software-Programms des ersten und des zweiten Kanals (A; B) miteinander verglichen werden und die Speicherprüfergebnisse (YA; YB) des zweiten Software-Programms des ersten und des zweiten Kanals (A; B) miteinander verglichen werden.
(EN)
The invention relates to a safety-relevant computer system, in particular a railway safety system, comprising at least two hardware channels (A; B), wherein memory check results of the channels (A; B) are fed to at least one comparator (3), which triggers an error response (4) if the memory check results are not equal. In order to be able to use diverse software programs created by compilers (X, Y), memory check results (XA, YA; XB, YB) of the diverse software programs of each channel (A; B) are fed to the comparator (3), wherein the memory check results (XA; XB) of the first software program of the first and second channels (A; B) are compared with each other and the memory check results (YA; YB) of the second software program of the first and second channels (A; B) are compared with each other.

L'invention concerne un système informatique lié à la sécurité, en particulier un système de sécurité de chemin de fer, présentant au moins deux canaux (A ; B) matériels, des résultats de tests de mémoire des canaux (A ; B) étant introduits dans au moins un comparateur (3), qui déclenche une réaction d'erreur (4) lors d'une différence entre les résultats de tests de mémoire. Pour pouvoir utiliser des logiciels diversifiés, réalisés par des compilateurs (X, Y), les résultats des tests de mémoire (XA, YA; XB, YB) des logiciels diversifiés de chaque canal (A ; B) sont introduits dans le comparateur (3), les résultats des tests de mémoire (XA; XB) du premier logiciel du premier canal et du deuxième canal (A ; B) étant comparés l'un à l'autre et les résultats des tests de mémoire (YA; YB) du deuxième logiciel du premier et du deuxième canal (A; B) étant comparés l'un à l'autre.
