Efficient On-line Schedulability Test for Feedback Scheduling of Soft Real-Time Tasks under Fixed-Priority
2008 Edition, April 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

When dealing with soft real-time tasks with highly variable execution times in open systems, an approach that is becoming popular is to use feedback scheduling techniques to dynamically adapt the bandwidth reserved to each task. According to this...

Efficient on-line schedulability tests for priority driven real-time systems
2000 Edition, January 1, 2000 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Many computer systems, such as those for open system environments or multimedia services, need an efficient schedulability test for online admission control of new jobs. Although various polynomial-time schedulability tests have been...

Feedback scheduling of model predictive controllers
2002 Edition, January 1, 2002 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The paper presents some preliminary results on dynamic scheduling of model predictive controllers (MPCs). In an MPC, the control signal is obtained by on-line optimization of a cost function, and the MPC task may experience very large variations in...

Markov Decision Process Based Energy-Efficient On-Line Scheduling for Slice-Parallel Video Decoders on Multicore Systems
2013 Edition, Volume 15, February 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We consider the problem of energy-efficient on-line scheduling for slice-parallel video decoders on multicore systems with Dynamic Voltage Frequency Scaling (DVFS) enabled processors. In the past, scheduling and DVFS policies in multi-core...

Feedback scheduling of control tasks
2000 Edition, Volume 5, January 1, 2000 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The paper presents a feedback scheduling mechanism in the context of co-design of the scheduler and the control tasks. We are particularly interested in controllers where the execution time may change abruptly between different modes, such as in...

Feedback scheduling of power-aware soft real-time tasks
2005 Edition, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we propose an energy-based feedback control scheduling framework for power-aware soft real-time tasks executing in dynamic environments, where real-time parameters are not known a priori. We propose the use of a...

Memory-Aware Feedback Scheduling of Control Tasks
2006 Edition, September 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents the incorporation of an auto-tuning real-time garbage collector into a feedback-based on-line scheduling system. The studied feedback scheduler is designed to dynamically adjust the sampling periods of a set...

A convex optimization approach to feedback scheduling
2008 Edition, June 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Adaptive tasks scheduling via feedback is an effective solution for the optimization of closed-loop control performance under computing power limitation, as in the computing nodes of embedded networked control systems. The problem of the...

Feedback scheduling for energy-efficient real-time homogeneous multiprocessor systems
2016 Edition, December 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Real-time scheduling algorithms proposed in the literature are often based on worst-case estimates of task parameters and the performance of an open-loop scheme can therefore be poor. To improve on such a situation, one can instead apply a...

Reservation-based feedback scheduling of MPC tasks
2007 Edition, Volume 18, March 1, 2007 - China Aerospace Science and Industry Corporation (CASIC)

A reservation-based feedback scheduling (FS-CBS) of a set of model predictive control (MPC) tasks is presented to optimize the global control performance subject to limited computational resource. Implemented as anytime algorithm, MPC task allows...
