+<h2 class="chapter">6 FFTW on the Cell Processor</h2>
+
+<p><a name="index-Cell-processor-329"></a>
+Starting with version 3.2, FFTW contains specific support for the Cell
+Broadband Engine (&ldquo;Cell&rdquo;) processor, graciously donated by the IBM
+Austin Research Laboratory.
+
+   <p>Cell consists of one PowerPC core (&ldquo;PPE&rdquo;) and of a number of
+Synergistic Processing Elements (&ldquo;SPE&rdquo;) to which the PPE can
+delegate computation.  The IBM QS20 Cell blade offers 8 SPEs per Cell
+chip.  The Sony Playstation 3 contains 6 useable SPEs.
+
+   <p>Currently, FFTW fully utilizes the SPEs for one- and multi-dimensional
+complex FFTs of sizes that can be factored into small primes, both in
+single and double precision.  Transforms of real data use SPEs only
+partially at this time.  If FFTW cannot use the SPEs, it falls back to
+a slower computation on the PPE.
+
+   <p>FFTW is meant to use the SPEs transparently without user intervention. 
+However, certain caveats apply, which are discussed later in this
+document.
