If you don't have a compiler that can produce code to take advantage of the underlying processor architecture and instruction set, then the fastest machines will be useless.
如果您没有可以生成代码来利用底层处理器架构和指令集的编译器，那么最快的机器也将是无用的。

In addition to processor clock speed, another important processor performance metric is clock cycles per instruction (CPI).
除了处理器时钟速度外，另一个重要的处理器性能度量是每条指令的时钟周期(CPI)。

Thus, whenever instruction addresses are presented to the processor (as in Branch instructions), the low-order two bits are ignored.
