The effective address is, under the hood, always split into a pair of 32-bit registers; the high-order register is optional and if it's not specified, it is treated as zero.
在这种情况下，有效地址总是分为两个32位的寄存器；高位寄存器是可选的，如果没有指定，就会被当作零进行处理。
The PPE accesses main storage (the effective-address space) with load and store instructions that move data between main storage and a private register file, the contents of which may be cached.
PPE用载入和存储指令访问主存储器(有效地址空间)，可以在主存储器与内容可以缓存的私有寄存器文件之间移动数据。
