Tasks in a real-time computing system are commonly periodic. Each instance generated by the invocation of a periodic task has normally a deadline constraint by which it must complete its execution in all circumstances. However, faults may be present in software, the electrical power supply may be depleted, the processor may be overloaded transiently etc.(More)
We present a new task model called BGW for preemptable, periodic task sets, scheduled on a uniprocessor embedded platform. The tasks may be subject to faults and the processor may be overloaded. According to BGW, any Black job has to execute a primary algorithm before deadline, any Grey job may execute either the primary or the back-up algorithm and any(More)
