Modern multiprocessor embedded systems execute a large number of tasks on shared processors and handle their complex communications on shared communication networks. Traditional methods from the HW/SW codesign or general purpose computing domain cannot be applied any more to cope with this new class of complex systems. To overcome this problem, a framework(More)
Oesophageal cancer is one of the most aggressive cancers and is the sixth leading cause of cancer death worldwide. Approximately 70% of global oesophageal cancer cases occur in China, with oesophageal squamous cell carcinoma (ESCC) being the histopathological form in the vast majority of cases (>90%). Currently, there are limited clinical approaches for the(More)
As single-processor systems are ceasing to scale effectively, multi-processor systems are becoming more and more popular. While there are many challenges of designing multi-processor systems in hardware, writing efficient parallel applications that utilize the computing capability of multiple processors may reveal to be even more challenging. In this paper,(More)
Energy optimization is a critical design concern for embedded systems. Combining D<scp>VFS</scp>&plus;D<scp>PM</scp> is considered as one preferable technique to reduce energy consumption. There have been optimal D<scp>VFS</scp>&plus;D<scp>PM</scp> algorithms for periodic independent tasks running on uniprocessor in the literature. Optimal combination of(More)
Power dissipation has constrained the performance boosting of modern computer systems in the past decade. Dynamic power management has been widely applied to change the system (or device) state dynamically to reduce the power consumption. This paper explores how to effectively reduce the energy consumption to handle event streams with hard real-time(More)
Energy consumption has become an important issue for modern embedded systems. This is because, one does not only like to deploy high-performance systems and provide guaranteed services, but also request system deployments to last as long as possible. With online dynamic power management (DPM), one adaptively changes the system's power mode, i.e., schedules(More)
Power dissipation has been an important design issue for a wide range of computer systems in the past decades. Dynamic power consumption due to signal switching activities and static power consumption due to leakage current are the two major sources of power consumption in a CMOS circuit. As CMOS technology advances towards deep sub-micron domain, static(More)
Many state-of-the-art approaches on fault-tolerant system design make the simplifying assumption that all faults are detected within a certain time interval. However, based on a detailed experimental analysis, we observe that perfect fault detection is not only an impractical assumption but even if implementable also a suboptimal design decision. This paper(More)
Effective power management is an important design concern for modern embedded systems. In this paper, we present an effective framework to integrate both DVS and DPM to optimize the overall energy consumption. We propose an online algorithm to determine the optimal operating frequency and mode transition of a processor based on the runtime workload. Our(More)
In the present study, we aimed to evaluate the protective effect of sesamin on kidney damage and renal endothelial dysfunction in two-kidney, one-clip renovascular hypertensive rats fed with a high-fat-sucrose diet (2K1C rats on HFS diet). Sesamin was intragastrically administered to 2K1C rats on HFS diet for eight weeks. Then, we measured the levels of(More)
