On the SPUs, most instructions can operate on registers as if they contained multiple, independent values (thus the single instruction acting on multiple data items).
在SPU上，大部分指令都可以在寄存器上进行操作，就仿佛它们分别包含多个无关的值一样(因此可以对多个数据项执行一条指令)。
Parallel computer architecture consists of two classifications: simple instruction stream-multiple data stream (SIMD) and multiple instruction stream-multiple data stream (MIMD).
并行计算机体系结构包括单指令流多数据流(SIMD)和多指令流多数据流(MIMD)两种结构。
