| Abstract(in English) | In this paper, we present an integer linear programming (ILP) model for a voltage scheduling problem. In the ILP model, we assume that the core processor can vary its supply voltage dynamically but can use only a single voltage level at a time. The objective function and constraint of ILP problem are energy consumption for given program and execution time, respectively. In addition, we prove basic theorems for variable voltage low power processors. The theorems indicate that the variable voltage scheduling with at most two voltages minimize energy consumption of processor. That is, only a single time voltage alteration while the program is running minimizes energy consumption. These theorems help to keep the energy and timing loss for voltage alteration to the minimum. The theorems must be a guideline to select optimal supply voltages which minimize energy consumption under a timing constraint. |
