SPU本身使用向量操作，每个时钟周期可以执行多达8条浮点指令。

An SPU USES vector operations itself and can thereby execute up to eight floating point instructions per clock cycle.

我们只需要供应它一个向量的方向，在这里，以逆时钟方向。支配它的运转的方向是从左到右，至少，在我们精神分析的写作中是这个方向。

One has only to provide it with a vectorial direction, here anti-clockwise-this is governed by the fact that, at least in our writing, you read things from left to right.

并使用时钟测试来减少生成测试向量所需的时间。

It can reduce the time used to generate the test vectors by using the clock test.
