While most research papers on computer architectures include some performance measurements, these performance numbers tend to be distrusted. Up to the point that, after so many research articles on data cache architectures, for instance, few researchers have a clear view of what are the best data cache mechanisms. To illustrate the usefulness of a fair(More)
SystemC is rapidly gaining wide acceptance as a simulation framework for SoC and embedded processors. While its main assets are modularity and the very fact it is becoming a de facto standard, the evolution of the SystemC framework (from version 0.9 to version 2.0.1) suggests the environment is particularly geared toward increasing the framework(More)
—Simulator development is already a huge burden for many academic and industry research groups; future complex or heterogeneous multi-cores, as well as the multiplicity of performance metrics and required functionality, will make matters worse. We present a new simulation environment, called UNISIM, which is designed to rationalize simulator development by(More)
When integrating mixed critical systems on a multi/many-core, one challenge is to ensure predictability for high criticality tasks and an increased utilization for low criticality tasks. In this paper, we address this problem when several high criticality tasks with different deadlines, periods and offsets are concurrently executed on the system. We propose(More)
INTRODUCTION Voluntary muscle contraction is accompanied by an increase in sympathetic nerve activity. The sympathetic skin response (SSR) is a simple and non-invasive method of autonomic assessment that reflects a synchronized activity of the sweat glands. The aim of our study was to examine the possible relationship between isometric muscle contraction(More)
In the past few years, several research works have demonstrated that sampling can drastically speed up architecture simulation, and several of these sampling techniques are already largely used. However, for a sampling technique to be both easily and properly used, i.e., plugged and reliably used into many simulators with little or no effort or knowledge(More)
Electrical stimulation of the lateral amygdala nucleus was found to evoke field potentials and influence unitary activity in the suprarhinal cortex of anesthetized rats. Laminar distributions of the field responses consisted of positive waves in superficial layers, that reversed to electronegatives from a depth of 0.4-0.5 mm. This response was followed by a(More)
