The Fast Fourier transform (FFT) is an efficient algorithm for computing the Discrete Fourier Transform. The FFT is a block-based algorithm.
This module describes a processor exercise in which students implement a spectrum analyzer using mixed C and assembly code. Students are to acquire a block of 1024 samples, apply a Hamming window, compute a length-1024 Discrete Fourier Transform using pr

This module describes a processor exercise in which students implement a spectrum analyzer using mixed C and assembly code. Students are to acquire a block of 1024 samples, apply a Hamming window, compute a length-1024 Discrete Fourier Transform using provided Fast Fourier Transform code, and display the magnitude-squared spectrum on an oscilloscope.

This module introduces the interactive optimizing compiler combination VPO/VISTA. VPO (Very Portable Optimizer) is a retargetable compiler developed at the University of Virginia. VISTA (VPO Interactive System for Tuning Applications), developed at Florida State University, is a GUI that allows a user to interactively select optimization steps with VPO feedback. Instructions are given on how to apply VPO/VISTA optimization to three routines provided in the power spectral density (PSD) estimator of the previous lab. Students are then asked to optimize these routines twice: once using VISTA and once using any method desired.
This is a basic guide to writing mex files for MATLAB in C. This guide gives a simple background of some the MATLAB mex features so that learning to write mex files can be quick and easy.
