This paper presents a novel usage-based characterization method to capture predesigned 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 MT X_MU LT8X8, which computes product of two 8 x 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.
