Extended Java-FFT Environment

This document presents a signal processing tool called Java–FFT for the codification of Kronecker products factors, called functional primitives, in language C. We present mathematical preliminaries for the addition of new functional primitives to a tool environment, which assist a developer in the generation of new algorithms based on Kronecker products algebra formulation. This tool is made to aid the analysis, design, modification, and implementation of Fast Fourier Transform (FFT) algorithms. The tool was written as Java applets, so it can be used with Internet browsers. The tool will be modified to include specifically two new functional primitives in the user interface. In the new version, the tool will generate C code that run efficiently on personal computers (PCs) by exploiting their architecture features
