console. While most consoles do everything possible to prevent unauthorized games from being playable on their system, the PS3 goes in the other direction, even providing direct support for installing and booting foreign operating systems. Of course, many of the game-related features such as video acceleration are locked out for the third-party operating systems, but this series focuses on more general-purpose and scientific applications anyway.
The real centerpiece for the PS3, however, is its processor -- the Cell Broadband Engine chip (often called the Cell BE chip). The Cell BE architecture is a radical departure from traditional processor designs. The Cell BE processor is a chip consisting of nine processing elements (note the PS3 has one of them disabled, and one of them reserved for system use, leaving seven processing units at your disposal). The main processing element is a fairly standard general-purpose processor. It is a dual-thread Power Architecture™ element, called the Power Processing Element, or PPE for short. The other eight processing elements, however, are a different story.
