Hard real-time systems must obey strict timing constraints. Therefore, one needs to derive guarantees on the worst-case execution times of a system's tasks. In this context, predictable behavior of system components is crucial for the derivation of ...

The Real-Time Specification for Java (RTSJ) provides an integrated approach to scheduling periodic real-time threads and monitoring their CPU execution time. It defines a cost enforcement model whereby a periodic real-time thread is suspended when it ...

Estimating the Worst Case Execution Time (WCET) of a program on a given processor is important for the schedulability analysis of real-time systems. WCET analysis techniques typically model the timing effects of micro-architectural features in modern ...

Mature research advances in scheduling theory show that carefully-crafted concurrent computational models permit static analysis of real-time behavior. This evidence enables designers to consider using suitable forms of explicit concurrency to model the ...

So far, performance measures for real time systems did not receive much attention. An assessment of the few existing benchmarking methods for real time systems will reveal that they are highly inappropriate. Taking a closer look into the fundamental issues ...

The Navy is a large user of real-time systems. A modern surface ship is deployed with hundreds of computers which are required for the ship to perform its mission. The Navy is moving away from using ’’niche‘‘ market components to meet its real-time ...

This paper presents the design and implementation of a user-level real-time network system in Real-Time Mach. Traditional network systems for microkernel based operating systems, which tend to focus on high performance and flexibility, are not suitable for ...
