Functional module model, pipelined circuit synthesis and pipelined circuit device

Abstract

The invention provides a functional module model for realizing optimal pipelining. The functional module model includes division line data representing division lines corresponding to positions where pipeline registers can be inserted and delay/area data representing the trade-off relationship between the delay and the area of each division area partitioned by the division lines. By using this functional module model, a pipeline register insertion position is selected among the division lines represented by the division line data, and the delay and the area of each division area are set on the basis of the trade-off relationship represented by the delay/area data. Thus, a pipelined circuit with a minimized area can be synthesized.
