  1. 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） 。
  2. The lk bit specifies whether the address of the next sequential instruction is saved in the link register as a return address for a subroutine call

    Lk位指定了下一個順序指令的地址是否作為子常式調用的返回地址保存在鏈接寄存器中。
  3. The ability to save the address of the next sequential instruction is provided on all branch instructions, including the branch to link register instruction

    所有的轉移指令都具備保存后繼順序指令地址的能力，包括到鏈接寄存器的轉移。
  4. An option provided for most load and store instructions is to update the base register in other words, ra with the data s effective address generated by the instruction

    用指令生成的數據有效地址來更新基址寄存器（也就是ra ）是大部分加載和存儲指令的一個可選項。
  5. A register in the processor that contains the address of the next instruction to be executed. also known as a program counter

    包含下一條要執行指令地址的處理器中的寄存器。也叫程序計數器。
