当PPE将一个数据字写入这个地址时，SPU就可以从对应的邮箱读通道中读取这个数据字的内容。
When the PPE writes a data word to that address, the SPU can read from its corresponding mailbox read channels.
可能由于短区段而增加操作时间的操作包括：查找区段、逻辑地址到物理地址的映射、轻量扫描、存档、预读、以及检查点刷新。
The operations that may take longer with short extents include: finding extents, mapping logical to physical addresses, light scans, archives, read-ahead, and checkpoint flush.
这个地址怎么读？
只读存储器。一个包括所的的每个地址只能被读，不能被写的存储器的大概分类。

输入起始的列地址，开始读操作。

另一示例是，与LUT相关的以其他方式不需要的寄存器可被用于为用户RAM模式提供同步读地址信号。
As another example, an otherwise unneeded register associated with a LUT can be used to provide a synchronous read address signal for user RAM mode.
代码访问违反意味着某个地方，试图访问(读，在这种情况下)内存不是映射到程序的地址空间。
An access violation means that somewhere, your code tried to access (read, in this case) memory that's not mapped to your program's address space.
不同内存地址的读可以与较早的写排序，同一地址的情况除外。
Reads may be reordered with older writes to different locations but not with older writes to the same location.
不同内存地址的读可以与较早的写排序，同一地址的情况除外。
