Last thing to do is increment our instruction address register by 1, and we’re done with another cycle.

最后要做的是将我们的指令地址寄存器递增 1，这样我们就完成了另一个周期。

As before, the last thing to do is increment our instruction address by 1, and another cycle is complete.

和以前一样，最后要做的是将我们的指令地址加 1，然后完成另一个周期。

Last thing to do is increment our instruction address register by 1, and we're done with another cycle.

最后要做的是将我们的指令地址寄存器递增 1，我们完成了另一个周期。

For this, we use an instruction address register, which as the name suggests, stores the memory address of the current instruction.

为此，我们使用一个指令地址寄存器，顾名思义，它存储当前指令的内存地址。

This causes the processor to overwrite the value in the instruction address register, which is currently 4, with the new value, 2.

这会导致处理器用新值 2 覆盖指令地址寄存器中当前为 4 的值。

The hallmarks of a von Neumann computer are a processing unit containing an arithmetic logic unit, data registers, an instruction register, and an instruction address register.

冯诺依曼计算机的标志是包含算术逻辑单元、数据寄存器、指令寄存器和指令地址寄存器的处理单元。

At a low level, this is done by writing the value specified in the last four bits into the instruction address register, overwriting the current value.

在低级别，这是通过将最后四位中指定的值写入指令地址寄存器，覆盖当前值来完成的。
