从__m128i转换为short或int [英] convertion from __m128i to short or int

问题描述

我该如何转换:
__128i * p =(__ m128i *)x;

到short * p =(short *)x;
?

how do i convert from:
__128i*p=(__m128i*)x;

to short*p=(short*)x;
?

推荐答案

答案是仅使用强制转换运算符:

The answer is simply using the cast operator:

short* p = (short *)x;

但是，我认为阅读有关 MMX 和 SSE 内在用法的这两篇文章可能对您很有用:

However, I think it could be useful for you to read these two articles about MMX and SSE intrinsics usage:
