I execute my instructions, and I am paid for doing so.

我执行我的指示，并因此获得报酬。

This meant our design required three clock cycles to execute one instruction.

这意味着我们的设计需要三个时钟周期来执行一条指令。

So even though this program is only 7 instructions long, the CPU ended up executing 13 instructions, and that's because it looped twice internally.

所以尽管这个程序只有 7 条指令长，但 CPU 最终执行了 13 条指令，这是因为它在内部循环了两次。

For example, many processors will have four, eight or more identical ALUs, so they can execute many mathematical instructions all in parallel!

例如，许多处理器会有四个、八个或更多相同的 ALU，因此它们可以并行执行许多数学指令！

For example, while executing an instruction that fetches a value from memory, the ALU is just going to be sitting there, not doing a thing.

例如，在执行一条从内存中获取值的指令时，ALU 只是坐在那里，什么都不做。

There's " infogreed" , a kind of desperate hunger for data at all costs; " syntaxmania" , an obsession with the " purity" of their code; and " datarush" , that thrill you get from successfully executing an instruction.

比如有“infogreed”，一种不惜一切代价对数据的绝望渴望；有“syntaxmania”，一种对代码的“纯粹”痴迷；还有“datarush”，一种从成功执行指令中获得的强烈快感。

For example, you might fetch something that the currently executing instruction is just about to modify, which means you'll end up with the old value in the pipeline.

例如，您可能会获取当前正在执行的指令即将修改的内容，这意味着您最终将在管道中获得旧值。

So why not fetch-and-decode several instructions at once, and whenever possible, execute instructions that require different parts of the CPU all at the same time! ?

那么，为什么不一次获取和解码多条指令，并尽可能同时执行需要 CPU 不同部分的指令！？

In an ideal case, pipelining lets you complete one instruction every single clock cycle, but then superscalar processors came along which can execute more than one instruction per clock cycle.

在理想情况下，流水线让您可以在每个时钟周期完成一条指令，但后来出现了超标量处理器，它可以在每个时钟周期执行多条指令。

You may have even heard of processors with MMX, 3DNow! , or SSE. These are processors with additional, fancy circuits that allow them to execute additional, fancy instructions - for things like gaming and encryption.

您甚至可能听说过带有 MMX、3DNow 的处理器！ , 或上交所。这些处理器带有额外的、奇特的电路，允许它们执行额外的、奇特的指令——比如游戏和加密。
