The spu_mfcdma64() function takes an additional argument specifying the top 32 bits of an effective address.
spu_mfcdma64()函数则使用另外一个参数来指定有效地址的高32位部分。
However, remember that they point to memory in the main storage of the application (an effective address), not to the SPE's local store.
但请记住它们指向在应用程序主存储内的内存(有效地址)，而非到SPE的本地存储。
In both modes, effective address computations use all 64 bits of the relevant registers (GPRs, LRs, CTRs, etc.) and produce a 64-bit result.
在两种模式下，有效地址计算将使用所有64位相关寄存器(GPR、LR、CTR等)并生成64位结果。
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。
A program references storage using the effective address computed by the processor when it executes a storage Access or Branch instruction or when it fetches the next sequential instruction.
在程序执行StorageAccess或Branch指令或者在存取下一条顺序指令时，它将使用处理器计算出的有效地址引用存储设备。
It is to say that each operating data stored in internal memory has its only exact address (physical address), composed of two parts: segment address and effective address.
即每一个存储在内部存储器上的操作数都有唯一确定的地址(物理地址)，这个地址由两部分构成：段地址和段内偏移地址。
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。
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。
