International Symposium on Low Power Electronics and Design (ISLPED)
作者: A. Acquaviva R. Scarsi Universita di Bologna Bologna Italy Politecnico di Turino Torino Italy
adaptive encoding has been shown to be an effective approach to bus power minimization in situations where characterization of the input statistics is not available. In this paper, we propose a novel technique for ada... 详细信息
