This paper proposes a new thermal nonlinear modeling technique for packaged integrated systems. Thermal behavior of complicated systems like packaged electronic systems may exhibit nonlinear and temperature dependent properties. As a result, it is difficult to use a low order linear model to approximate the thermal behavior of the packaged integrated(More)
Efficient temperature estimation is vital for designing thermally efficient, lower power and robust integrated circuits in nanometer regime. Thermal simulation based on the detailed thermal structures no longer meets the demanding tasks for efficient design space exploration. The compact and composable model-based simulation provides a viable solution to(More)
This paper proposes a new thermal modeling method for package design of high-performance microprocessors. The new approach builds the thermal behavioral models from the given accurate temperature and power information by means of the subspace method. The subspace method, however, may suffer predictability problem when the practical power is given as a(More)
Temperature estimation and prediction are critical for online regulation of temperature and hot spots on today's high performance processors. In this paper, we present a new method, called FRETEP, to accurately estimate and predict the full-chip temperature at runtime under more practical conditions where we have inaccurate thermal model, less accurate(More)
AIM To analyze the causes, demographic and socio-cultural aspects, and the magnitude of burn injuries prospectively and to evaluate the outcome of treatment of patients admitted to burns ICU of tertiary care hospital. MATERIALS AND METHODS A total of 892 burn patients admitted over a period of 6 years from January 2002 to December 2007 at tertiary care(More)
Accurate runtime power estimation is important for on-line thermal/power regulation on today's high performance processors. In this paper, we introduce a power calibration approach with the assistance of on-chip physical thermal sensors. It is based on a new error compensation method which corrects the errors of power estimations using the feedback from(More)
INTRODUCTION Trauma and injury severity score (TRISS), introduced in 1981 is a combination index based on revised trauma score (RTS), injury severity score (ISS) and patient's age. In this study we have used TRISS method to predict the outcome in trauma cases. MATERIALS AND METHODS 1000 consecutive cases of trauma of adult age group admitted in casualty(More)
—Efficient temperature estimation is critical for designing thermal efficient, low power and robust integrated circuits in nanometer regime. Thermal simulation starts from the detailed thermal structures by solving thermal diffusion equations no longer meets demanding tasks for efficient design space exploration. Compact and composable model-based(More)
In this paper, we propose a new behavioral thermal modeling technique for high-performance microprocessors at package level. Firstly, the new approach applies the subspace identification method with the consideration of practical power maps with correlated power signals. We show that the input power signal needs to meet an independence requirement to ensure(More)
