What is not usually apparent to new assembly language programmers is that the order of instructions affects the speed of the program.

对于新入门的汇编语言程序员来说，不太明显的一个问题是指令的顺序会影响程序执行速度。

The extra information then overlays a part of the running program and causes the runtime to execute instructions that it should not execute.

那么多出的信息会覆盖正在运行的程序的一部分，导致运行时执行本不应该执行的指令。

So, for the price of at most a few instructions, your program can have the provability of a functional program and the speed and memory characteristics of an imperative one.

从而，在只是付出了一些指令的代价后，您的程序会拥有函数式程序的可证明性和命令式程序的速度和内存特性。

And if the test is true, it will change the value of this program counter to point to some other place in the memory, some other point in that sequence of instructions, and you'll keep processing.

如果测试结果为真，它会改变程序计数器的结果去,指向记忆存储器里的其他地方，指令序列里的其他地方，然后你会继续这个过程。

What that means, in a stored-program computer, is that I can provide to the computer a sequence of instructions describing the process I want it to execute.

它的意思就是说，我可以给一个存储程序计算机,提供一系列,描述我希望,能执行的过程的指令。

Remember last time, I said that there's different kinds of complexity in our code, and I suggested for simple branching programs, the amount of time it takes to run that program is, in essence, bounded by the number of instructions, because you only execute each instruction at most once.

但是这里有个很重要的点,记得上节课，我提过在我们的代码中，有不同种类的复杂度，而且我还说了对于简单的分支程序,运行这种程序需要的总体时间,大体上，是和指令的数目相关的,因为每个指令只会被执行最多一次。

Using a software program to compare the sequences of the genes that give the instructions for making egg proteins, they show that teleosts with floating eggs share a gene called VtgAa.

This program is then fed into a second piece of software called a compiler, which translates it into a sequence of machine instructions for a specific kind of microprocessor, such as Intel's x86 family, which can then run the original program.
