The selected system architecture consists of a 2 out of 2 schema, in which one channel acts as Master and the other as Slave. Each redundant channel uses a microcontroller as central element. The present analysis demonstrates that this system fulfills SIL-4 requirements. Once the system architecture is detailed, the system overall functionality and the data flow are presented. Then, the microcontroller's internal architecture is explained, and the software voting process flow-diagram is discussed. Afterward, the resources of the microcontroller architecture that are used for the execution of each task involved in the software voting process (hardware-software interaction) are determined. Finally, a fault analysis is elaborated to demonstrate that the cases in which the safety requirements are compromised have a very small occurrence probability, i.e., the hazard rate of proposed voting is below 1E-9.}, language = {English}, number = {3}, journal = {Ieee Transactions on Industrial Electronics}, author = {Idirin, Mikel and Aizpurua, Xabier and Villaro, Almir and Legarda, J. and Melendez, Juan}, month = mar, year = {2011}, note = {WOS:000287323800012}, keywords = {Data corruption, IF1.740, safety analysis, sil-4, software voting}, pages = {822--829} }"]
