System calls. when an emulator ordinarily encounters a powerpc system call instruction, it emulates the exception by storing the instruction address into the srr0 register, setting some architecture - defined bits in srr1, and transferring control to physical address 0xc00. some powerpc variants allow more control over this behavior, but this is the traditional powerpc model
當模擬器正常地碰到一個powerpc系統調用指令時，它便將指令地址存入到srr0寄存器，設置srr1中某些體系結構定義的位，並將控制權轉交給物理地址0xc00 ，從而模擬這個異常（有些powerpc的變種允許對這種行為有更多的控制，但是這里的這種是傳統的powerpc模型） 。 -
