Since open platforms such as Android vary in device manufacturers and application developers, modifications in software happened in multiple layers. Therefore, every layer including OS, library, framework and application may have defects within. Especially, a memory leakage which increases memory usage and diminish overall system performance is the key issue in embedded systems with highly limi...

Leakage power is becoming dominant part of the microprocessor chip power budget as feature size shrinks. Leakage energy consumption is of particular concern in memory structures, such as on-chip caches, for large scale transistors and rare access. Chipmakers have proposed many low leak circuit techniques for cache leakage control, in which gated-vdd and DVS are two effective methods. In this pa...

abstract profile monitoring in statistical quality control has attracted attention of many researchers recently. a profile is a function between response variables and one or more independent variables. there have been only a limited number of researches on monitoring multivariate profiles. indeed, monitoring correlated multivariate profiles is a new subject in the fileld of statistical process...

The cost-effectiveness of unilateral emission abatement can be seriously hampered by emission leakage. We assess three widely-discussed proposals for leakage reduction targeted at energyintensive and trade-exposed industries: border tax adjustments, output-based allocation and industry exemptions. We find that none of these measures amounts to a “magic bullet” when both efficiency and equity cr...

This paper describes a technique for integrating run time compilation which is e ectively pause free and for which the worst case impact can be bounded Three extensions to a JVM implementation are used Firstly a new scheduler allows the allocation of CPU time to threads to be controlled Secondly a code generator provides a mechanism for run time compilation Finally a control interface allow app...

Task scheduling is one of the main challenges in every system design, and especially in embedded systems design. Task scheduling might be classified in two broad categories: (1) compile time (static scheduling) or (2) run time (dynamic scheduling). Recently there has been a growing interest in the development of run-time scheduling techniques for platform-based designs [1][2]. This interest is ...
