CPU

n.[计算机]中央处理器

Once the power of a computer is turned on, all the behaviors are under the control of CPU.

计算机一旦通电运行，则所有的行为都要在它的控制之下运行。

Each controller on a bus can be individually addressed by the CPU, this is why the software device driver can write to its registers and thus control it.

在总线上的每个控制器可以被CPU所单独寻址，这是软件设备驱动程序能写入寄存器并能控制这些控制器的原因。
