程序计数器指示存储器当中的某些位置，尤其是指示序列中的第一个指令。
That program counter points to some location in memory typically to the first instruction in the sequence.
程序存储器的导址逻辑是由寄存器来实现的，这个寄存器叫程序计数器。
This program memory addressing logic is handled by a register referred to as a program counter.
如果测试结果为真，它会改变程序计数器的结果去，指向记忆存储器里的其他地方，指令序列里的其他地方，然后你会继续这个过程。
And if the test is true, it will change the value of this program counter to point to some other place in the memory, some other point in that sequence of instructions, and you'll keep processing.
