Therefore in series production redundant hardware concepts like dual core microcontrollers running in lock-step-mode are used to reach ASIL D safety requirements given from the ISO 26262. Coded processing is capable of reducing redundancy in hardware by adding diverse redundancy in software, e.g. by specific coding of data and instructions. A system with two coded processing channels is considered. One channel is active and one is in cold standby. When the active channel fails, the service is switched from the active channel to the standby channel. It is imaginable that the two channels with implemented coded processing are running with time redundancy on a single core or on a multi core system where for example different ASIL levels are partitioned on different cores. In this paper a redundant concept based on coded processing and software rejuvenation will be taken into account.}, language = {en} } @inproceedings{BraunMottokMiedletal., author = {Braun, J{\"u}rgen and Mottok, J{\"u}rgen and Miedl, Christian and Geyer, Dirk and Minas, Mark}, title = {Capability of single hardware channel for automotive safety applications according to ISO 26262}, series = {2012 International Conference on Applied Electronics (AE 2012), Pilsen, Czech Republic, 5 - 7 September 2012}, booktitle = {2012 International Conference on Applied Electronics (AE 2012), Pilsen, Czech Republic, 5 - 7 September 2012}, isbn = {978-80-261-0038-6}, pages = {41 -- 45}, language = {en} } @inproceedings{BraunMottokMiedletal., author = {Braun, J{\"u}rgen and Mottok, J{\"u}rgen and Miedl, Christian and Geyer, Dirk and Minas, Mark}, title = {Overview and Evaluation of Fail-Safe and Fault-Tolerant Mechanisms for the Electromobility according to ISO26262}, series = {1st International Electromobility Congress, 12. - 13. 5. 2011, Prague}, booktitle = {1st International Electromobility Congress, 12. - 13. 5. 2011, Prague}, pages = {5}, language = {en} } @article{BraunGeyerMottok, author = {Braun, J{\"u}rgen and Geyer, Dirk and Mottok, J{\"u}rgen}, title = {Alternative measure for safety related software}, series = {ATZelektronik}, journal = {ATZelektronik}, number = {04}, issn = {1862-1791}, pages = {40 -- 43}, abstract = {Wie kann die funktionale Sicherheit in Fahrzeugen zukunftssicher und effektiv gew{\"a}hrleistet werden?
