An overview of DSP optimization techniques, from the design stage, through high-level implementations, to assembly implementations.
Many tricks and techniques have been developed to speed up the computation of FFTs. Significant reductions in computation time result from table lookup of twiddle factors, compiler-friendly or assembly-language programming, special hardware, and FFT algorithms for real-valued data. Higher-radix algorithms, fast bit-reversal, and special butterflies yield more modest but worthwhile savings.

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.
