ABSTRACT With new technologies, temperature has become a major issue to be considered at system level design. Without taking temperature aspects into consideration, no approach to energy or and performance optimization will be sufficiently accurate and efficient. In this paper we propose an on-line temperature aware dynamic voltage and frequency scaling (DVFS) technique which is able to exploit both static and dynamic slack. The approach implies an offline temperature aware optimization step and online voltage-frequency settings based on temperature sensor readings. Most importantly, the presented approach is aware of the frequency-temperature dependency, by which important additional energy savings are obtained.

    ABSTRACT: This paper presents a novel statistical-based approach to Worst-Case Response-Time (WCRT) analysis of complex real-time system models. These system models have been tailored to capture intricate execution dependencies between tasks, inspired by real industrial control systems. The proposed WCRT estimation algorithm is based on Extreme Value Theory (EVT) and produces both WCRT estimates together with a probability of being exceeded. By using the tools developed, an evaluation is presented using three different simulation models, and four other methods as reference: Monte Carlo simulation, MABERA, HCRR and traditional Response-Time Analysis (basic RTA). Empirical results demonstrate that the benefit of the proposed approach, in terms of 1) reduced pessimism when compared to basic RTA and 2) validated guarantee of never being less than the actual response time values. The proposed approach also needs much fewer simulations compared to other three simulation-based methods.

    ABSTRACT: As the semiconductor technology proceeds into the deep sub-micron era, the leakage and its dependency with the temperature become critical in dealing with power/energy minimization problems. In this paper, we study the problem on how to schedule a hard real-time system to achieve the minimal overall energy, including both dynamic and leakage energy consumption. We first develop an energy estimation method that can be used to accurately and efficiently calculate the overall energy consumption of a candidate schedule. Based on the proposed energy equation, we then develop two scheduling methods, i.e. an off-line and an on-line method, to minimize the overall energy consumption for real-time systems. Our experimental results demonstrate that the proposed energy estimation method can achieve up to two orders of magnitude speedup compared with an existing approach while maintaining good accuracy. In addition, with a large number of different test cases, both our off-line and on-line approaches can significantly outperform existing related works.

    ABSTRACT: Many-core chips interconnected by networks-on-chip (NoC) are increasingly challenged by the tight power consumption constraints. The concept of voltage and frequency island (VFI) which has been recently introduced for achieving fine-grain core-level power management fits well with an NoC design style. This paper will discuss some recent advancement of VFI optimizations for many-core/NoC designs. We will also discuss other research challenges for low-power many-core/NoC designs from an electronic system level (ESL) perspective.
