Abstract

Abstract: According to the logic value of an adjacent signal, the coupling dynamic dissipation of the adjacent signal is computed. The method is used in calculating the dynamic dissipation of the N bit bus during M, so the average dissipation factor p_M is obtained to reflect the average power of the N bit bus. With the datafile of the program address bus, the best routing of the bus is searched for by computing the lowest p_M. As a result, the dynamic dissipation of the bus is reduced by 38.2％.

Key words: low-power, adjacent signal, dissipation factor, routing
