If you hesitate before moving or neglect to move promptly, your mem will be wiped off by time.

如果你在行动前犹豫不决，或者不及时行动，你记忆信息就会被时间抹去。

If signals from America's GPS constellation are jammed, they can tune into Russia's glonas, Europe's Galileo or China's bado MEMS and satellite signals typically reinforce one another Americas joint direct attack.

如果来自美国 GPS 星座信号受到干扰，它们可以调谐到俄罗斯 glonas、欧洲 Galileo 或中国 bado MEMS，而卫星信号通常会相互加强美洲联合直接攻击。

I didn't have enough money and then the checkout lady insisted on counting every single coin and the people behind mem were getting really annoyed and it was so embarrassing.

我没有足够钱，然后收银员坚持要清点每一枚硬币，mem 背后很生气，这太尴尬了。

One thing to note is that sometimes MEMS oscillators are used in smartphones to save space instead of crystal oscillators, and we'll dive into MEMS in a future episode.

需要注意是， 有时手机会使用MEMS振荡器来节省空间， 而不是石英晶体振荡器，我们将在未来节目中详细介绍MEMS。

And also we have microelectromechanical systems, or MEMS, which covers the technology of microscopic devices with moving parts.

此外，我们还拥有微机电系统（简称MEMS），它涵盖了带有活动部件微观设备技术。

We don't have to jump back into the code that called the mem copy.

我们不必跳回调用内存副本代码。

Down below the battery is an additional small circuit board that holds the main MEMS microphone, which is about the size of a grain of rice.

电池下方还有一个小型电路板， 上面装有主MEMS麦克风，大小约等于一粒米。

We mem copy that descriptor with that length that we set to two here and this descriptor into that DMA buffer.

我们用我们在这里设置为 2 那个长度复制那个描述符，并将这个描述符复制到那个 DMA 缓冲区中。

So we take a bunch of our payload, copy it over the stack, and then the mem copy is done.

所以我们拿了一堆我们有效载荷，把它复制到堆栈上，然后内存复制就完成了。

So what does the copy operation look like? If we do the mem copy, it looks like this.

那么复制操作是什么样子呢？如果我们进行 mem 复制，它看起来像这样。

We control mem copies return pointer, and we capture the flow of control profit.

我们控制mem拷贝return指针，我们捕获控制利润流量。

That means we can copy more than two bytes using this mem copy function.

这意味着我们可以使用此内存复制功复制两个以上字节。

The mem copy would return to this function because of the saved return points around the stack, which we overwrote.

由于我们覆盖了堆栈周围保存返回点，内存副本将返回到此函数。

But this descriptor length here is used down below in that mem copy.

但是这里描述符长度在下面内存副本中使用。

And what then happens is that down below here, a mem copy happens where that response, this is the response that the host waits for on that control request because it wants to get the status.

然后发生是，在下面下方，一个内存副本发生在该响应位置，这是主机等待该控制请求响应，因为它想要获得状态。

But what if we copy eight kilobytes? If we set that w length to eight kilobytes, then the mem copy operation is going to copy that variable plus 8,190 bytes into that DMA buffer from the stack.

但是如果我们复制 8 KB 呢？如果我们将 w 长度设置为 8 KB，那么内存复制操作将把该变量加上 8,190 字节从堆栈复制到 DMA 缓冲区中。

And the interesting thing is on the stack, the stack in the C language is used if you do a function call to the mem copy, for example.

有趣是在堆栈上，例如，如果您对 mem 副本进行函数调用，则使用 C 语言中堆栈。
