The Rough Guide scientific computing on the PlayStation 3
As much as the Sony PlayStation 3 (PS3) has a number of interesting features, it's the heart of the CELL processor is what the fuss is all about. CELL, CELL Broadband engine architecture, also abbreviated CBEA cell be architecture or, in abbreviated form, is a microprocessor, which is jointly developed by Sony, Toshiba, and IBM, an Alliance known as the STI.
In 2000, the STI Design Center in Austin, Texas, and four years with about 400 engineers and consumed nearly half billion dollars. The initial goal was to outperform desktop systems, design, implementation, available at the time of the magnitude through a dramatic increase in the performance of the chip area and power consumption of the unit of measure. A quantum leap in performance is achieved by abandoning the outdated model, which is the result of a history of the architecture mechanisms such as caching hierarchies and speculative execution, which in those days brought diminishing returns in performance gains. Instead, the new architecture would depend on a heterogeneous multi-core design with a very powerful processors. Their architecture to be removed from the costly and inefficient features such as address translation, teaching, reordering, register renaming, and branch prediction. Instead, they should be given a powerful short-vector SIMD capabilities and a massive register file. Cache hierarchies is replaced by a small and fast local memories and effective DMA engines. This design approach has led to 200 million transistors a chip, which today offers performance hardly approachable billion transistor-terparts in the countries and served in a wide range of computing the audience truly off-the-shelf way via a $ 600 gaming console.
