Leakage Minimization Using Self Sensing and Thermal Management
The authors have developed a system architecture, measuring and modeling techniques, and algorithms for on-line power and energy optimization and thermal management. The starting point for their approach is a simple and small gate-level network that can be used for real-time and low overhead measurement of temperature on chip positions where their network gates are placed. They use linear programming and interpolation to calculate the temperature at any arbitrary point of the integrated circuit. The periodic calculations of the temperature are used to estimate locally dissipated energies, which are consequently used to derive the most efficient use of operational times to minimize the overall leak-age energy.
