This is known as SIMD (single instruction, multiple data), or data parallelism.
这种技术称为SIMD(单指令，多数据)或数据并行。
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)。
In audio applications, the single-instruction, multiple data (SIMD) mode effectively doubles the processor performance.
在音频应用中，单指令多数据(SIMD)模式实际上可使处理器性能提高一倍。
