_m_pmaxsw#

__m64 _m_pmaxsw(__m64 a, __m64 b);

Intel Description

Compare packed signed 16-bit integers in “a” and “b”, and store packed maximum values in “dst”.

Intel Implementation Psudeo-Code

FOR j := 0 to 3
        i := j*16
        dst[i+15:i] := MAX(a[i+15:i], b[i+15:i])
ENDFOR

__m64 _m_pmaxub(__m64 a, __m64 b);

Intel Description

Compare packed unsigned 8-bit integers in “a” and “b”, and store packed maximum values in “dst”.

__m64 _m_pminsw(__m64 a, __m64 b);

Intel Description

Compare packed signed 16-bit integers in “a” and “b”, and store packed minimum values in “dst”.

Intel Implementation Psudeo-Code
