White Paper
The Cell Broadband Engine (CBE, shortname “Cell”) is a nine-core implementation of the Cell Broadband Engine
Architecture (CBEA), including a 64-bit Power Processor
Element (PPE) and eight Synergistic Processor Elements
(SPEs). We apply this processor’s computational power
to the calculation of a large FFT, comprising 16 million
(224) single-precision complex samples. We present an
overview of the CBE, discuss Cell code development
methodology, explore the challenges and the tradeoffs of
this particular task, describe some implementation details,
and present results.
