Instead, the SPU can access any 128-bit word in the local store at L1cache speed.
相反,SPU可以以L1缓存的速度来访问本地存储器中的任何128位的字。

If a program reads a single byte in memory, the processor loads the whole cache line that contains that byte into the L2 and L1 caches.
如果一个程序在存储中读到一个单独的字节,处理器就会释放包含字节的所有的缓存线到L2和L1缓存中。

Such an access is serviced by the processor's L1cache and the data is read or written all at once; it cannot be affected halfway by other processors or threads.
