Usage-based characterization of complex functional blocks for reuse in behavioral synthesis

This paper presents a novel usage-based characterization method to capture pre-designed complex functional blocks for automatic reuse in behavioral synthesis. We identify attributes necessary for reuse of such complex components and illustrate how the attributes are captured into a design database. A complex component MTX-MULT 8/spl times/8, which computes product of two 8/spl times/8 matrices, is captured with the proposed method, and its reuse in behavioral synthesis is demonstrated with design of a DCT example. Feasibility of the method for capturing various components is demonstrated as well.
