# FFTW Home Page

Introduction FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST). We believe that FFTW, which is free software, should become the FFT library of choice for most applications. The latest official release of FFTW is version 3.3.4, available from our download page. Version 3.3 introduced support for the AVX x86 extensions, a distributed-memory implementation on top of MPI, and a Fortran 2003 API. Version 3.3.1 introduced support for the ARM Neon extensions.

[OMAPL138] Hello DSPLink Program - OMAPL1x Processors Forum - OMAP™ Processors - TI E2E Community - Iceweasel
It's been a few days, no much progress. What I have done is: 1, Re-configured the dsplink using command: perl dsplinkcfg.pl --platform=OMAPL138 --nodsp=1 --dspcfg_0=OMAPL138GEMSHMEM --dspos_0=DSPBIOS5XX --gppos=ARM --comps=ponslrmc --trace=1 --DspTskMode=1 This turns on the trace function. 2, Re-build dsplink following this link:
Discrete Fourier transform
Relationship between the (continuous) Fourier transform and the discrete Fourier transform. Left column: A continuous function (top) and its Fourier transform (bottom). Center-left column:Periodic summation of the original function (top).
Demonstrations Project
The Fourier descriptors of a shape are calculated as follows. 1. Find the coordinates of the edge pixels of a shape and put them in a list in order, going clockwise around the shape.2. Define a complex-valued vector using the coordinates obtained. For example: . 3.

thrust - Code at the speed of light
We no longer maintain the Thrust project on Google Code. Find Thrust's new home at thrust.github.com Thrust is now hosted on Github! Thrust v1.6.0 has been released! Refer to the CHANGELOG for changes since v1.5.1 Thrust v1.5.1 has been released! Version 1.5.1 is distributed with CUDA 4.1 and fixes an uncommon sorting bug (see CHANGELOG).

Karl's Calculus Tutor: 1.0 Number Systems
Calculus deals with properties of the real numbers. In order to understand calculus you must first understand what it is about the real numbers that separates them from other kinds of numbers we use from day to day. 1.1 The Counting Numbers These are the first numbers we learn. When we count, we start from one and list off the names of numbers in sequence.

OMAP3 DSP MMU Configuration - Texas Instruments Embedded Processors Wiki - Iceweasel
What are TLBs? The OMAP35xx MMU has Translation Lookaside Buffers (TLB). The TLB is a cache the allows the MMU to accelerate virtual to physical address translation by holding the most recent translations. For example if there is a TLB hit then the translation will be retrieved from the TLB cache.
