A generative approach to building a framework for hard real-time applications
- In 31st Annual NASA Goddard Software Engineering Workshop
, 2007
"... The communication and tasking infrastructure of a real-time application makes up a significant portion of any em-bedded control system. Traditionally, the tasking and com-munication constructs are provided by an RTOS. We present an approach to automatically generate a robust framework for a single-n ..."

Some investigations on FCFS scheduling in hard real-time applications
- J. Comput. System Sci
, 1991
"... We investigate some real time behaviour of a (discrete time) single server system with FCFS task scheduling. The main results deal with the probability distribution of a random variable SRD(T), which describes the time the system operates without violating a fixed task service time deadline T. The t ..."

Using Lock-Free Objects in Hard Real-Time Applications
"... Lock-based approaches to object sharing are the accepted means of interprocess communication in realtime systems. The main problem that arises under such approaches is that of priority inversion, i.e., the situation in which a given task1 waits on another task of lower priority to exit a critical se ..."

of a task holding a semaphore is at least that of the highest-priority taskthatlocks that semaphore. In [1], we propose using lock-free objects as an alternative for object sharing in real-time systems. Lock-free
parMERASA – multicore execution of parallelised hard real-time applications supporting analysability
- in 2013 Euromicro Conference on Digital System Design (DSD), 2013
"... Abstract-Engineers who design hard real-time embedded systems express a need for several times the performance available today while keeping safety as major criterion. A breakthrough in performance is expected by parallelizing hard real-time applications and running them on an embedded multi-core p ..."

A Profile-Based Energy-Efficient Intra-Task Voltage Scheduling Algorithm for Hard Real-Time Applications
- In Proceedings of the International Symposium on Low-Power Electronics and Design
, 2001
"... Intra-task voltage scheduling (IntraVS), which adjusts the supply voltage within an individual task boundary, is an effective technique for developing low-power applications. In this paper, we propose a novel intra-task voltage scheduling algorithm for hard real-time applications based on average-ca ..."

A Flexible Run-time Support for Distributed Dependable Hard Real-time Applications
- In Proceedings of the 2nd International Symposium on Object-oriented Real-time distributed Computing
, 1999
"... Typically, most distributed, dependable, real-time systems designed in the past can only meet the particular requirements of the application domain to which they were targeted. This approach led to specific, non-flexible, dedicated and non-reusable solutions, often based on specialized hardware. Thi ..."

. This paper presents an alternative approach where a flexible run-time support for distributed dependable hard real-time applications is built on top of off-theshelf hardware. This support has been designed by considering three fundamental and complementary aspects: realtime, to support applications
Impact of Power-Management Granularity on The Energy-Quality Trade-off for Soft And Hard Real-Time Applications
"... Abstract — In this paper we introduce the concepts of work of tokens (e.g. video frames) in an application, and slack arising from variations in work. Slack is used for dynamic voltage and frequency scaling in combination with a conservative power-management policy that never misses deadlines, for h ..."

, for hard real-time applications, and with a nonconservative policy for soft real-time applications. We evaluate both policies for a number of different granularities (frequency of activation of the power manager) on an MPEG4 application, on energy and quality (deadline misses). We conclude that for soft
HADES: A distributed System for Dependable Hard Real-Time Applications Built from COTS Components
, 2000
"... Most dependable embedded real-time systems designed in the past have been specialized to meet the specific requirements of the application domain for which they were targeted, leading to inflexible and often hardware-intensive solutions that are costly to design and maintain. This paper is devoted t ..."

For economic and maintainability reasons, this infrastructure is based entirely on Commercial Off-The-Shelf (COTS) components (motherboard, network and real-time kernel). The Hades run-time
Timing analysis of mixed-criticality hard real-time applications implemented on distributed partitioned architectures
- In 17th IEEE International Conference on Emerging Technologies and Factory Automation
, 2012
"... In this paper we are interested in the timing anal-ysis of mixed-criticality embedded real-time applications mapped on distributed heterogeneous architectures. Mixed-criticality tasks can be integrated onto the same architec-ture only if there is enough spatial and temporal separa-tion among them. W ..."
