Searchable:

MMX-Swizzle-XMM

Register:

XMM 128 bit

Return Type:

__m64

Param Types:

__m64 a, __m64 b

Param ETypes:

UI8 a, UI8 b

__m64 _mm_unpackhi_pi8(__m64 a, __m64 b);

Intel Description

Unpack and interleave 8-bit integers from the high half of “a” and “b”, and store the results in “dst”.

Deprecated since version X87: MMX technology intrinsics can cause issues on modern processors and should generally be avoided. Use SSE2, AVX, or later instruction sets instead, especially when targeting modern processors.
