·先进的POWER和Power PC体系结构 IBM不仅于1975年首先发明了RISC技术,在1990年又第一个推出了第二代超标量RISC:POWER。POWER2处理器中,有多个运算单元,每个时钟周期可同时执行多达6条指令,浮点运算能力超过270SPECfp92,同时改进了系统总线带宽,可达2000MB/s以上。Power PC处理器浓缩了POWER体系结构的精华和当今最先进的微处理器技术,具有非常均衡的整数和浮点运算能力,无论是单CPU系统,还是SMP对称多处理器系统,都提供了优良的性能和性能价格比。 ·卓越的性能和最大的扩展能力
Advanced POWER and Power PC architecture IBM not only invented RISC technology first in 1975, but also the first to introduce the second generation of superscalar RISC: POWER in 1990. POWER2 processor, there are multiple computing units, each clock cycle can perform up to six instructions at the same time, floating-point computing power over 270SPECfp92, while improving the system bus bandwidth, up to 2000MB / s or more. The POWER PC processor, which has condensed the best of POWER architecture and today’s state-of-the-art microprocessor technology, with well-balanced integer and floating-point capabilities, offers superior performance in either single-CPU or SMP symmetric multiprocessor systems The performance and cost performance. Excellent performance and maximum scalability
