The challenge today

�For many years, organizations have relied on performance gains from increasing clock speeds of “traditional” microprocessor architectures

�This approach has been challenged by the physical limitations ofsemiconductors and by traditional processor architecture implementations

�High performance computing (HPC) applications need a fundamentally new technology and approach to the system-level architecture to achieve the desired level of performance.

Performance highlights

� Performance is an order of magnitude better than general purposeprocessors (GPP) for media and certain applications that can take advantage of its Single Instruction Multiple Data (SIMD) capability

– Performance of its simple Power Processor Element (PPE) is comparable to a traditional GPP performance

– Each Synergetic Processor Element (SPE) is able to perform mostly the same as a GPP running at the same frequency

– Key performance advantage comes from its eight de-coupled SPE engines with dedicated resources including large register files and DMA channels

� Accelerates targeted applications with extraordinary processing capabilities– Floating-point operations

– Integer operations

– Data streaming / throughput support

– Real-time support

� Open architecture allows for optimization at compiler and application level– Performance gains from tuning compilers and applications can be significant

– Tools/simulators are provided to assist in performance optimization efforts
