今天我们要从硬件向软件迈出第一步！使用上一集我们构建的CPU，我们将运行一些指令，并引导您了解程序如何在机器级别运行。

我们将向您展示如何使用不同的程序来执行不同的任务，以及软件如何解锁硬件中未内置的新功能。这一集和上一集一样非常复杂，但别担心——随着我们进入编程阶段，这个机器级别的操作码、地址和寄存器的概念将像本系列中的许多概念一样被抽象出来。

Today we’re going to take our first baby steps from hardware into software! Using that CPU we built last episode we’re going to run some instructions and walk you through how a program operates on the machine level. We'll show you how different programs can be used to perform different tasks, and how software can unlock new capabilities that aren't built into the hardware. This episode, like the last is pretty complicated, but don’t worry - as we move forward into programming the idea of opcodes, addresses, and registers at this machine level will be abstracted away like many of the concepts in this series.
