Abstract

In this paper, we study the problem of behavioral-level partitioning for low power design. By behavioral-level partitioning, we mean a partitioning which is done at the behavioral description where scheduling and allocation have not been carried out. The motivation is that turning on/off individual operations cycle-by-cycle is very expensive, thereby we provide a partitioning solution so that all operations in the same partition can be controlled by the same gated clock signal. Our partitioning algorithm is specifically focused on the applications which contain many nested conditional branches and loops.
