ChronOS Linux: a best-effort real-time multiprocessor Linux kernel
We present ChronOS Linux, a best-effort real-time Linux kernel for chip multiprocessors (CMPs). ChronOS addresses the intersection of three problem spaces: a) OS-support for obta...

Parallel, hardware-supported interrupt handling in an event-triggered real-time operating system
A common problem in event-triggered real-time systems is caused by low-priority tasks that are implemented as interrupt handlers interrupting and disturbing high-priority tasks th...

Hardware support for real-time operating systems
The growing complexity of embedded applications and pressure on time-to-market has resulted in the increasing use of embedded real-time operating systems. Unfortunately, RTOSes ca...

TOSSTI: Saving Time and Energy in TinyOS with Software Thread Integration
Many wireless sensor nodes (motes) interface with slow peripheral devices, requiring the processor to wait. These delays waste time, energy and power, which are valuable but limit...

Approximation algorithms for power minimization of earliest deadline first and rate monotonic schedules
We address power minimization of earliest deadline first and ratemonotonic schedules by voltage and frequency scaling. We prove that the problems are NP-hard, and present (1+ ) f...
