However, the problem is that vector processing assumes that each and every instruction will be applied to all elements of the vector.
然而,问题是向量处理会假设每条指令都可以适用于向量的所有元素。

For instance, spu_add (myvec, 2) generates an ai (add immediate) instruction, while spu_add (myvec, 2000) first loads the 2000 into its own vector using il and then performs the a (add) instruction.
