Extract Packed Single-Precision Floating-Point Values

Encoding

Description

The (V)EXTRACTPS instruction extracts a single-precision floating-point value from the source operand. The selected value is indicated by the bits 0..1 in the immediate (the other bits are ignored). The extracted value is stored in the destination operand.

Operation

public void EXTRACTPS(ref U32 dest, SimdU32 src, byte imm8)
{
    dest = src[imm8 & 3];
}

public void VEXTRACTPS_Vex(ref U32 dest, SimdU32 src, byte imm8) =>
    EXTRACTPS(ref dest, src, imm8);

public void VEXTRACTPS_Evex(ref U32 dest, SimdU32 src, byte imm8) =>
    EXTRACTPS(ref dest, src, imm8);

Intrinsics

int32_t _mm_extract_ps (__m128 a, const int idx)
