译码单元由指令缓存器和指令译码器构成，针对12位的指令代码翻译成16位控制信号，传送给处理器内部各个部件，用以保证各部件正常工作。

The encoding unit, composed of instruction buffer and command encoder, translates the 12-bit command code to 16-bit control signal, and ensures each part of the system to work steadily.

这些指令被翻译成二进制代码，这是计算机容易处理的一种形式。

The instructions are translated into binary code, a form that computers can easily handle.

《柯林斯英汉双解大词典》

早期的程序设计利用机器代码指令在裸机层次上完成。

Early programming was done at the bare machine level, using machine code instructions.

And I want to remind you, that block of code is a set of instructions, the same set of instructions that are going to be done each time through the loop.

我想提醒大家,这块代码是一个指令集,一个每次循环都会被执行的相同指令集,会变化的仅仅是变量的值。

And that does two things: bug one, it helps catch bugs in your code, and secondly it often converts it into a more efficient sequence of instructions before you actually go off and run it. All right?

这有两点好处：,第一是可以帮助你发现程序中的，第二是把你的代码,在运行之前,转换为更有效率的指令的集合，对不对？

If it does, then execute each of the instructions in that block.
