As much as the Sony PlayStation 3 (PS3) has a number of interesting features, the heart is what is going on the CELL processor. Cell, a shorthand for CELL broadband engine architecture, also abbreviated as cell architecture or CBEA, is a microprocessor, which together by the Alliance of Sony, Toshiba and IBM, known as STI developed.
The work began about 400 engineers involved in the year 2000 on the STI Design Center in Austin, Texas, and more than four years and consumes almost half a billion dollars. The original goal was to desktop systems, at the time of the completion of design, an order of magnitude, to exceed power consumption and chip area by a dramatic increase in performance per unit. A quantum leap in performance would by abandoning the outdated architecture model performance based on where mechanisms such as cache hierarchies and speculative execution, brought at that time decreasing performance gains to be achieved. Instead, the new architecture on a heterogeneous multi-core design with highly efficient data processing would will leave the heart. Its architecture would be features such as address translation, taken away from costly and inefficient instructions reorder, rename and branch register prediction. Instead she would be given powerful short vector SIMD capabilities and a massive register file. Cache hierarchies would be replaced by small and fast local memories and high-performance DMA engine. This design approach led performance a 200 million transistors chip, which delivers today hardly accessible through its billion transistor of countries Terparts and is $600 of the wide IT community available in a really commercially available manner on a video game console.
