Abstract:

Energy consumption has recently emerged as one of the most critical design constraints. It directly relates to the operating time of a portable device. Most researches on pipelined circuits address the optimization of logic blocks to achieve low power. Among the power reduction techniques, the bipartition approach is comparatively effective as it partitions a given circuit into two subcircuits such that only a selected subcircuit is activated at a time, hence reducing unnecessary signal transitions. However operation time of a system is correlated to energy dissipation rather than power dissipation. In this paper, we propose a bipartition algorithm which aims to reduce switching probabilities such that the energy dissipation of combinational blocks as well as pipelined registers are reduced. Transistor-level simulation results show that our proposed algorithm reduces not only the power dissipation but also delay for most of the benchmark circuits.
