As a consequence, the instruction set contains mostly arithmetic and branch operations but none that resemble kernel mode instructions of the PPE.

结果是指令集中包含大部分算术操作和转移操作，但是并不包含PPE中的那种内核模式指令。

You set some registers and issue a system call instruction (or an interrupt) and have the kernel code called directly from the trap handler.

你可以设置一些寄存器，并发出一个系统调用指令(或中断)，并由陷阱处理程序直接调用内核代码。
