The Cell Broadband Engine is a multi-core chip architecture jointly developed by IBM, Sony, and Toshiba. It is derived from IBM's Power Architecture, which was once used in Apple notebooks and desktops. Today, IBM uses the Cell processor in a line of blade servers.
Samples of the SE1000 chip began shipping from Toshiba on April 8. Toshiba has said it expects sales of 6 million units within the first three years.

Some other features of the SpursEngine: Its multimedia engine can deliver up to 48 GFlops (billion Floating point operations per second) or 12GFlops per processing element. Every element has 256KB of integrated memory. The circuit board (photo) supports a PCI-Express Base Specification Revision 1.1.
Toshiba also plans to release a TV with the Cell processor.
