Dual Management of Real-Time and Interactive Jobs in Smartphones

چکیده
A dual management of real-time and interactive jobs in dual-core smartphones is presented. The proposed scheme guarantees the end-to-end QoS of real-time applications, while also provides reasonable latency for interactive applications. To this end, high performance NVRAM is adopted as storage of real-time applications, and a dual purpose CPU scheduler, in which one core is exclusively used for real-time applications, is proposed. Experiments show that the proposed scheme reduces the deadline miss ratio of real-time applications by 92%. key words: real-time job, smartphone, NVRAM, scheduling

Real-time Scheduling of a Flexible Manufacturing System using a Two-phase Machine Learning Algorithm
The static and analytic scheduling approach is very difficult to follow and is not always applicable in real-time. Most of the scheduling algorithms are designed to be established in offline environment. However, we are challenged with three characteristics in real cases: First, problem data of jobs are not known in advance. Second, most of the shop’s parameters tend to be stochastic. Third, th...
متن کاملA Non-Preemptive Two-Class M/M/1 System with Prioritized Real-Time Jobs under Earliest-Deadline-First Policy
This paper introduces an analytical method for approximating the performance of a two-class priority M/M/1 system. The system is fully non-preemptive. More specifically, the prioritized class-1 jobs are real-time and served with the non-preemptive earliest-deadline-first (EDF) policy, but despite their priority cannot preempt any non real-time class-2 job. The waiting class-2 jobs can only be s...
متن کاملTowards Concurrent Execution of Real-time and Interactive Jobs in NAND Flash Based Portable Devices
With enhanced capabilities of portable devices such as PMPs and MP3 players, the application range supported by a single portable device is extended widely. For example, not only traditional realtime programs like a video player, but also interactive applications such as web browsers and text editors are supported together. This requires the redesign of legacy portable devices that have been de...

Supply chain excellence has a real huge impact on business strategy. Building supply chains (SCs) as flexible system represents one of the most exciting opportunities to create value. This requires integrated decision making amongst autonomous chain partners with effective decision knowledge sharing among them. The key to success lies in knowing which decision has more impact on the supply chai...
متن کاملThe Reliability and Concurrent Validity of Digital Inclinometer, Smartphone Applications, and the Cervical Range of Motion Device for Measuring the Cervical Range of Motion
Objectives: Changes in the Range of Motion (ROM) are essential criteria in determining the severity of spinal disorders and could be effective in predicting pain progression. Instruments to measure the ROM are costly and unavailable in most therapy settings. While there is a tendency in therapists to use their smartphones instead, there is no report to measure the suitability of smartphones to ...
