High-level synthesis of low-power VLSI processors and its efficient search method

摘要

The emergence of mobile computing and mobile communication devices such as laptop computers, cellular phones, wireless modems, etc., drive the needs for low-power design of VLSI processors. Moreover, development of high-level methodologies for low-power design becomes important because of increasing complexities of VLSI processors. The use of multiple supply voltages is one efficient technique to obtain low-power implementations at reduced performance overheads. This paper presents an integer linear programming model for energy-consumption minimization using multiple supply voltages. Moreover, an efficient genetic algorithm is proposed based on a new crossover method using cutsets of a data-flow graph.
