20.500.12556/DKUM-26293-e9fcfd05-1a01-18cf-a1c9-52f65796b346 A safety shell for UML-RT projects A safety shell pattern was defined based on a reconfiguration management pattern, and inspired by the architectural specifications in Specification PEARL. It is meant to be used for real-time applications to be developed with UML-RT as described. The implementation of the safety shell features as defined by in [8], namely its timing and state guards as well as I/O protection and exception handling mechanisms, is explained. The pattern is parameterised by defining the properties of its components as well as by defining the mapping between software and hardware architectures. Initial and alternative execution scenarios as well as the method for switching between them are defined. The goal pursued with the safety shell is to obtain clearly specified operation scenarios with well defined transitions between them. To achieve safe and timely operation, the pattern must provide safety shell mechanisms for an application designed, i.e., enable its predictable deterministic and temporally predictable operation now and in the future. real-time systems embedded systems UML profiles UML patterns safety sistemi v realnem času vgrajeni sistemi UML profili UML vzorci varnost true false false Angleški jezik Angleški jezik Neznano 2012-05-31 12:24:49 2012-05-31 12:24:49 2023-08-16 14:40:21 2024-01-03 03:24:32 2008 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 004.43.05 12727830 URN:SI:UM:DK:HH4I0LQ2 http://www.proceedings2008.imcsit.org/pliks/26.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=35262 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
