Conference Paper: Optimal manufacturing flow to determine minumum operating voltage.
[Show abstract] [Hide abstract]
ABSTRACT: A technique to optimize power determines the minimum operating voltage during manufacturing testing on a per die basis. The die is then programmed to operate at the minimum voltage for the life of the die. Silicon results to evaluate the effectiveness of a variety of techniques to determine the minimum voltage of a die, in a manufacturing environment, are presented. Based on this we propose an adaptive hybrid test flow that is guaranteed to compute the minimum voltage while minimizing test time. Finally, sample data on power optimization achievable using power reduction is provided.2011 IEEE International Test Conference, ITC 2011, Anaheim, CA, USA, September 2022, 2011; 01/2011 
Conference Paper: Effective Supervisors for Predictive Methods of Dynamic Power Management
[Show abstract] [Hide abstract]
ABSTRACT: The paper presents new supervisors dedicated to predictive methods of dynamic power management, i.e. DCT (dynamic clock throttling), DFS (dynamic frequency scaling), and DVS (dynamic voltage scaling). The presented supervisors make decisions on the basis of current chip temperature; future, current and previous power dissipations. They consist in cooperation with operating system and they are dedicated to high efficiency systems. The proposed supervisors can be implemented in both software and hardware, e.g. as neural network. Not only performance gain but also energy profit can be made in systems that use these supervisors. Simulations results of considered cases show that theoretical improvement of the ideal supervisor is in the range of 7.38 to 16.17% for performance and of 2.47 to 9.88% for energy. The profit of the real supervise method depends on the complexity of supervisor.Mixed Design of Integrated Circuits and Systems, 2007.

ABSTRACT: Given a circuit netlist, based on the slack analysis in the netlist, the optimal voltage in a maximum slacksharing cluster(MSC) can be obtained to maintain the performance of the netlist. Furthermore, according to the optimal voltages of all the MSCs and the constraints for multiplevoltage assignment, an efficient assignment approach is proposed to assign multiple voltages onto the given circuit netlist for lowpower optimization in this paper. The experimental results show that our proposed assignment approach has 10%∼56% reduction of power consumption in multiplevoltage assignment for all the tested circuits.Circuits and Systems and TAISA Conference, 2008.
