Design method for parameterized IP generator using structural and creational design patterns

Parameterized intellectual property (IP) core generators, which produce synthesizable hardware design based on predefined microarchitectural-level parameters, can improve the efficiency of IP reuse. However, the process of designing such IP core generators is usually time-consuming and error-prone because it has to couple SW with HW designs in one product. In this paper, we propose a pattern-oriented design method for parameterized IP core generators. The paper shows that IP core generators quality can be improved through combining structural design pattern with creational design pattern. We also demonstrate the method through a soft-decision Viterbi decoder generator application.
