假如跳转目标是重复执行，那么程序将对这一步重复执行，就是说这个程序步里的所有指令将被重新发送执行。
If the Jump destination is "repeat", then the program will repeat the same step, which means it will issue all the commands in the step.
在现代的处理器中，HLT停机指令节省了大量的电能与执量，空闲任务几乎总是由一个重复执行HLT停机指令的循环组成。
On modern processors, where a HLT (halt) instruction saves significant amounts of power and heat, the idle task almost always consists of a loop which repeatedly executes HLTinstructions.
