Managing latency in embedded streaming applications under hard-real-time scheduling
- In Proceedings of the 8th IEEE/ACM/IFIP International Conference on Hardware/Software Codesign and System Synthesis
, 2012
"... In this paper, we consider the problem of hard-real-time scheduling of embedded streaming applications, modeled us-ing dataflow graphs, while minimizing the application la-tency. Recently, it has been shown that the actors in an acyclic Cyclo-Static Dataflow (CSDF) graph can be sched-uled as a set o ..."

Real-Time Dynamic Voltage Scaling for Low-Power Embedded Operating Systems
, 2001
"... In recent years, there has been a rapid and wide spread of nontraditional computing platforms, especially mobile and portable computing devices. As applications become increasingly sophisticated and processing power increases, the most serious limitation on these devices is the available battery lif ..."

On Maximizing Reliability of Real-Time Embedded Applications Under Hard Energy Constraint
"... Abstract—The dynamic voltage and frequency scaling (DVFS) technique is the basis of numerous state-of-the-art energy management schemes proposed for real-time embedded systems. However, recent research has illustrated the alarmingly negative impact of DVFS on task and system reliability. In this pap ..."

Handling Execution Overruns in Hard Real-Time Control Systems
- IEEE Trans. Computers
, 2002
"... AbstractÐIn many real-time control applications, the task periods are typically fixed and worst-case execution times are used in schedulability analysis. With the advancement of robotics, flexible visual sensing using cameras has become a popular alternative to the use of embedded sensors. Unfortuna ..."

Adaptive Dynamic Power Management for Hard Real-time Pipelined Multiprocessor Systems
"... Abstract—Energy efficiency is a critical design concern for embedded systems. Dynamic power management (DPM) schemes in Multiprocessor System on Chips (MPSoCs) has been wildly used to explore the idleness of processors and dynamically reduce the energy consumption by putting idle processors to low-p ..."

In this paper, we explore how to effectively apply dy-namic power management in adaptive manner to reduce leakage power consumption for coarse-grained pipelined systems under hard real-time requirements. At each adaptive point, a system transformation is proposed to model the pipeline system
Process Cruise Control: Event-Driven Clock Scaling for Dynamic Power Management
, 2002
"... Scalability of the core frequency is a common feature of low-power processor architectures. Many heuristics for frequency scaling were proposed in the past to find the best trade-off between energy efficiency and computational performance. With complex applications exhibiting unpredictable behavior ..."

In this paper we propose an energy-aware scheduling policy for non-real-time operating systems that benefits from event counters. By exploiting the information from these counters, the scheduler determines
