Unless otherwise specified, the FFTLIB package installs under C:\ti\ in directory fftlib_k2hx_2_0_1_3. The directory structure of the installed package will look similar to that displayed below in Figure 1, though the install folder will match the installation version.

ERROR: UNRECOGNIZED TARGET

The files that comprise the FFTLIB installation can be categorized into the following seven categories.

  1. Documentation
  2. Component Repository
  3. Kernel Directories
  4. Eclipse Support

The sections that follow provide details for each category.

 

Documentation

Installation places all FFTLIB documentation in a Docs directory in the FFTLIB root. The following documentation comes with the delivery:

 

Component Repository

The installation creates a Components directory in the FFTLIB root folder. This directory serves as a repository for all packages included in the FFTLIB installation. Each package in this repository is compressed.
 

Kernel Directories

The installation also creates a Packages directory in the FFTLIB root folder. This directory holds all kernels contained within the FFTLIB library. This directory follows the standard TI directory structure. As an example, the files that comprise the FFTLIB kernel FFT_sp_1d_r2c_batch will be located, relative to the FFTLIB root installation directory, at packages/ti/fftlib/src/FFT_sp_1d_r2c_batch/.

Each Kernel is delivered with a pre-compiled CCS project that illustrates the kernel API and performs several validation tests. Each project provides an estimate of kernel cycle and program memory requirements.

 

Eclipse Support

The Eclipse directory contains all files required for FFTLIB to be recognized by Eclipse (CCS) as a plug-in. This is a support directory and can be safely ignored.
