基本操作
- 使用SSE专门的LOAD指令将数据从内存加载一个向量到寄存器；
- 使用SSE专门的OP指令对两个向量进行某种计算；
- 使用SSE专门的STORE指令把计算结果从寄存器写回到内存；
数据类型
- __m128表示128bit的单精度浮点数
typedef union __declspec(intrin_type) __declspec(align(16)) __m128 {
float m128_f32[4];
unsigned __int64 m128_u64[2];
__int8 m128_i8[16];
__int16 m128_i16[8];
__int32 m128_i32[4];
__int64 m128_i64[2];
unsigned __int8 m128_u8[16];
unsigned __int16 m128_u16[8];
unsigned __int32 m128_u32[4];
} __m128;
- __m128i表示128bit的整数型
typedef union __declspec(intrin_type) __declspec(align(16)) __m128i {
__int8 m128i_i8[16];
__int16 m128i_i16[8];
__int32 m128i_i32[4];
__int64 m128i_i64[2];
unsigned __int8 m128i_u8[16];
unsigned __int16 m128i_u16[8];
unsigned __int32 m128i_u32[4];
unsigned __int64 m128i_u64[2];
} __m128i;
- __128d表示128bit的双精度浮点数
typedef struct __declspec(intrin_type) __declspec(align(16)) __m128d {
double m128d_f64[2];
} __m128d;
指令函数命名
SSE指令的函数从命名上，主要分成三部分，以_mm_loadu_pd为例：
- 第一部分均以_mm开头，表示属于SSE指令集，_mm256或_mm512是AVX或AVX-512指令集的Intrinsic函数前缀；
- 第二部分表明操作类型，比如load，add，store等。但部分指令后面跟有[l|h|u|r]等字母，比如u表示mem_addr不需要内存对齐，r表示反向读取等；
- 第三部分为操作的对象名及数据类型：
_ps：packed操作所有的单精度浮点数；
_pd：packed操作所有的双精度浮点数；
_pixx：（xx为长度，可以是8，16，32，64）packed操作所有的xx位有符号整数，使用的寄存器长度为64位；
_epixx：（xx为长度）packed操作所有的xx位的有符号整数，使用的寄存器长度为128位；
_epuxx： packed操作所有的xx位的无符号整数；
_ss：scalar操作第一个单精度浮点数；
p表示packed即对128bits的数据全部执行相同的操作，s表示scalar，只对128bits中的第一组数据执行操作，如下图所示。
