Streaming applications come from various application fields such as physics, where data is continuously generated and must be processed on the fly. Typical streaming have a series-parallel dependence graph, they are hierarchical failure-prone platform, for instance in miniaturized satellites. The goal to minimize energy consumed when processing each set, while ensuring real-time constraints ter...

Currently, the on-chip wireless communication system (OWCS) includes 2nd-generation (2G), 3rd-generation (3G), and long-term evolution (LTE) communication subsystems. To improve the power consumption of OWCS, a typical architecture design of system power control unit (SPCU) is given in this paper, which can not only make a 2G, a 3G, and an LTE subsystems enter sleep mode, but it can also wake t...

This paper presents a model of inductor based DC-DC converters that can be used to study the impact of power management techniques such as dynamic voltage and frequency scaling (DVFS). System level power models of low power systems on chip (SoCs) and power management strategies cannot be correctly established without accounting for the associated overhead related to the DC-DC converters that pr...

Abstract The enormous energy consumed by cloud data centers (CDCs) increases the carbon footprints, operational cost and decreases system reliability, so it becomes a great challenge for CDCs providers. Dynamic voltage frequency scaling (DVFS) is an efficient approach efficiency, which reduces operating frequency, supply of processor during task’s execution. Recent research shows that has negat...

Relentless scaling of silicon fabrication technology coupled with lower design tolerances are making ICs increasing susceptible to wear-out related permanent faults as well as transient faults. A well known technique for tackling both transient and permanent faults is redundant execution, specifically space redundancy, wherein a program is executed redundantly on different processors, pipelines...

Increased leakage current and device variability are the major challenges with CMOS technology scaling. Since Static Random Accessed Memory (SRAM) is often the largest component in the embedded digital systems or System-on-Chip (SoC), it is more vulnerable to those challenges. To effectively reduce SRAM leakage and/or active power, supply voltage (VDD) is often scaled down during standby and/or...

The recruitment phenomenon, that is, the reduced dynamic range between threshold and uncomfortable level, is attributed to the loss of instantaneous dynamic compression on the basilar membrane. Despite this, hearing aids commonly use slow-acting dynamic compression for its compensation, because this was found to be the most successful strategy in terms of speech quality and intelligibility reha...

In this paper, Stochastic Activity Networks (SANs) are exploited to model and evaluate the power consumption and performance of virtualized servers in cloud computing. The proposed SAN models the physical servers in three different power consumption and provisioning delay modes, switching the status of the servers according to the workload of the corresponding cluster if required. The Dynamic V...

The emergence of multi-core and many-core architectures in embedded systems has increased the energy and thermal challenges faced by such systems. As the technology for microprocessors moves toward the nanometer scale, power density becomes one of the major constraints to the performance improvement of embedded processors. Realtime embedded signal processing tasks on multi-core systems have a h...
