The POWER6 chip has two hardware instruction threads that are both capable of issuing multiple instructions per cycle, which causes a boost in performance.
POWER 6处理器有两个能够在每个处理器周期发出多条指令的硬件指令线程，从而改善了性能。
The POWER5 chip has two hardware instruction threads that are both capable of issuing multiple instructions per cycle, which causes a boost in performance.
POWER 5芯片有两个硬件指令线程，在每个周期都能够执行多个指令，这可以提高性能。
By knowing instruction retired per cycle, the system knows how fast the current application is executing inside the processor.
通过知晓每循环的指令重试，系统就知晓了处理器内部正在执行的当前应用程序有多快。
More instruction retired per cycle, the better performance the application is getting.
每循环的指令重试越多，该应用程序获取的性能就越好。
At per cycle, processor fetch many instruction from many thread to manage operation.
在每个周期，处理机从多个线程取出多条指令调度执行。
It is more efficient to design a simple instruction set that enable the execution of one instruction per clock cycle.
设计一个能够在一个时钟周期执行一条指令的简单指令系统才是更有效的。
