Research paper thumbnail of A preemptive priority-based disk I/O subsystem for the management of hard real-time disk traffic

The proposed disk I/O subsystem allows the invocation of preemptive priority based disk I/O operations, both for non contiguous and contiguous data layouts. Disk I/O requests are scheduled in a common layer upon the disk driver, where access to

Nowadays DAAS applications are designed according to the specific needs of each particular field. These solutions produce

We describe a prototype implementation on a Real-Time Java Server, developed as an application level server on the Real-Time Mach microkernel environment. The Java virtual machine has been extended to support filesystem bandwidth reservation facilities existing on Real-Time Mach. Such facilities allow continuous media applications to specify their disk

Multimedia data are essentially continuous, heterogeneous, and isochronous, three characteristics with strong real-time implications when combined. At the same time, some multimedia services, like video-on-demand or distributed simulation, are real-time applications with sophisticated temporal functionalities in their user interface. We analyze the

Research paper thumbnail of Characterization of blocking time in real-time systems with dynamic priority ceilings

Proceedings Ninth Euromicro Workshop on Real Time Systems, 1997

It is shown that worst case blocking times do not always reach the total duration of the critical sections which produce them. Our characterization allows the real time system designer to attain a higher processor utilization factor while the tasks meet all their deadlines
