An in-place, in-order address generation scheme is proposed for the realization of prime factor mapping (PFM). The new approach has the characteristic of forming systematic and regular structures. Hence it is suitable for realizations using both high-level and low-level languages. Furthermore, it requires very few modulo operations and no modulo inverse for its computation; such inverses often take up memory space for their storage and/or extra time for the computation in other address generation algorithms. The approach has been implemented using Fortran 77 and the assembly language of the 320C25 DSP. It shows that a maximum of 86% saving in address generation time can be achieved as compared to the conventional approach.
