+\subsection{Cell Broadband Engine}
+Cell Broadband Engine is a microprocessor architecture jointly developed by Sony, Sony Computer Entertainment, Toshiba, and IBM.
+The first major commercial application of Cell Broadband Engine was in Sony's PlayStation 3 game console.
+The Cell processor can be split into four components:
+external input and output strctures, the main processor called the Power Processing Element (PPE),
+eight fully functional co-processors called the Synergistic Processing Elements or SPEs,
+and a specialized high-bandwidth circular data bus connecting the PPE, input/output elements and the SPEs,
+called the Element Interconnect Bus or EIB (Figure \ref{fig:cell_arch}).
