Portability methods in parametrized DSP module generators

Parametrized module generators can be widely utilized in the VLSI implementations of digital signal processing systems. By making the generators portable one can significantly simplify their later reutilization. The portability can be addressed either on system level, on macroblock level, or on leaf cell level. The applicable methods for achieving the portability on different levels are classified and reviewed. Practical and efficient methods for facilitating the technology porting to the next generation technologies are highlighted in example cases
