....researchers have attacked the same problem by generating off line schedules [3] 4] 5] A major disadvantage of such a solution is that it cannot be handled by a standard priority based RTOS. Furthermore, they do not support pre emption, sporadic activities, and varying task execution times. In [6] [7] a method is presented for translating offline schedules to task attributes for fixed priority systems (FPS) This method could be combined with methods in [3] 4] 5] and would enable the use of priority based RTOS for those methods. However, the combined approached would still inherit the ....
....on line acceptance test for sporadic and aperiodic tasks to use spare capacity from the tasks translated from the offline schedule to FPS, while the methods presented in this paper add no ran time overhead for managing sporadic tasks. Moreover, when translating an off line schedule the method in [6] [7] in some cases have to represent an off line scheduled task by more than one FPS task. This can result in an FPS system with artificial tasks and thereby a greater number of tasks compared to our method. However, if more instances are used it is possible to find solutions that cannot be found ....
