A Block Floating Point Implementation for an N-Point FFT on the TMS320C55x DSP

Texas Instruments

Published Date: 09/01/2003

Description

A block floating-point (BFP) implementation provides an innovative method of floating-point emulation on a fixed-point processor. This application report implements the BFP algorithm for the Fast Fourier Transform (FFT) algorithm on a Texas Instruments (TI) TMS320C55x? DSP by taking advantage of the CPU exponent encoder. The BFP algorithm as it applies to the FFT allows signal gain adjustment in
