Autonomic computing systems are capable of adapting their behavior and resources thousands of times a second to automatically decide the best way to accomplish a given goal despite changing environmental conditions and demands. Different decision mechanisms are considered in the literature, but in the vast majority of the cases a single technique is applied(More)
Nowadays, the same piece of code should run on different architectures, providing performance guarantees in a variety of environments and situations. To this end, designers often integrate existing systems with ad-hoc adaptive strategies able to tune specific parameters that impact performance or energy—for example, frequency scaling. However, these(More)
This article presents a detailed overview and the experimental comparison of 15 multi-objective design-space exploration (DSE) algorithms for high-level design. These algorithms are collected from recent literature and include heuristic, evolutionary, and statistical methods. To provide a fair comparison, the algorithms are classified according to the(More)
Electronic components in space applications are subject to high levels of ionizing and particle radiation. Their lifetime is reduced by the former (especially at high levels of utilization) and transient errors might be caused by the latter. Transient errors can be detected and corrected using memory scrubbing. However, this causes an overhead that reduces(More)
In real time systems, random caches have been proposed as a way to simplify software timing analysis, by avoiding corner cases usually found in deterministic systems. Using this random approach, one can obtain an application's probabilistic Worst Case Execution Time (pWCET) to be used for timing analysis. As with deterministic systems, technology scaling in(More)
In recent years, random caches have been proposed as a way to simplify the timing analysis of real-time systems. However, technology-scaling makes caches prone to faults. Fault detection mechanisms can detect permanent faults but they affect the timing analysis of a random cache. This paper introduces a Static Probabilistic Timing Analysis (SPTA) technique(More)
