Floating-Point Arithmetic with theTMS32020

Abstract

This report presents algorithm and code implementing floating-point addition, subtraction, multiplication, and division with theTMS320. The support of floating-point operations by the TIprocessors has made possible some applications, such asimplementation of the CCITT Adaptive Differential Pulse CodeModulation (ADPCM) algorithm and image/graphics operations.
