PowerPC使用了加载/存储（也成为RISC）指令集，这意味着访问主存的惟一时机就是将内存加载到寄存器或将寄存器中的内容复制到内存中时。
The PowerPC uses a load/store (also called RISC) instruction set, which means that the only time it accesses main memory is for loading into registers or copying a register to memory.
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。
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.
SPE用直接内存访问（DMA）命令访问主存储器，可以在主存储器与称为本地库或本地存储（LS）的私有本地内存之间移动数据和指令。
The SPEs access main storage with direct memory access (DMA) commands that move data and instructions between main storage and a private local memory, called a local store or local storage (LS).
存储单位和执行单位分工明确，可以不受指令访问范围限制，成块地扩充内存。
The memory unit and the performance unit work clearly with each other. The blocks can extend the memory at virtually no limit.
本发明公开了一种动态随机访问存储器（DRAM）的控制器及用户指令处理方法。
