Thermal sensor allocation and placement for reconfigurable systems

Temperature monitoring using thermal sensors is an essential tool for evaluating the thermal behavior and sustaining the reliable operation in high-performance and high-power systems. With current technology scaling and integration trends timely and accurate detection of localized heating will be evermore important. In this work, we address the creation of a resource efficient sensor infrastructure for computing systems that are of regular nature, such as logic array-based computing platforms. We propose algorithms to embed thermal sensors into a regular structure to minimize the number of sensors and determine sensor locations required to maintain a given accuracy in temperature sensing for a given design. Our algorithms are tailored for minimal usage of thermal sensors to suit a variety of architectural conditions. For programmable logic arrays the highly application-specific usage of the hardware resources leads to unpredictable thermal profiles. As a result, post-manufacture insta...
