Scheduling Fixed-Priority Tasks with Preemption Threshold
While it is widely believed that preemptability is a necessary requirement for developing real-time software, there are additional costs involved with preemptive scheduling, as co...

Non-Blocking Data Sharing in Multiprocessor Real-Time Systems
A non-blocking protocol that allows real-time tasks to share data in a multiprocessor system is presented in this paper. The protocol gives the means to concurrent real-time tasks...

Hard Real-Time Garbage-Collection in the Jamaica Virtual Machine
Java's automatic memory management is the main reason that prevents Java from being used in hard realtime environments. We present the garbage collection mechanism that is us...

Dynamic Adjustment of Serialization Order Using Timestamp Intervals in Real-Time Databases
Although an optimistic approach has been shown to be better than locking protocols for real-time database systems (RTDBS), it has the problems of unnecessary restarts and heavy re...
