Fixed-Point Toolbox

Introduction

Fixed-Point Toolbox™ provides fixed-point data types and arithmetic in MATLAB^®. The toolbox lets you design fixed-point algorithms using MATLAB syntax and execute them at compiled C-code speed. You can reuse these algorithms in Simulink^® and pass fixed-point data to and from Simulink models, facilitating bit-true simulation, implementation, and analysis. The toolbox also enables you to generate test sequences for fixed-point software and hardware verification.

Example of fixed-point computation in MATLAB: Convolution of two fixed-point variables.
