相对于64位地址空间，我们首先来看一下32位地址空间这个概念。
First is the concept of a 32-bit address space, as opposed to a 64-bit address space.
尽管处理器可以存储32位地址值，但是高8位(实际上在68008中多于8位)并没有被使用，因此这样做也不会产生什么影响。
Although the processors can store 32-bit address values, the top eight bits (actually more than eight, on the 68008) are not wired to anything, and have no effect.
