stdarch_x86_avx512_f16 #127213)Available on (x86 or x86-64) and target feature
avx512fp16 and x86-64 only.Expand description
Multiply the lower complex number in a by the complex conjugate of the lower complex number in b,
accumulate to the lower complex number in c using zeromask k (the element is zeroed out when the corresponding
mask bit is not set), and store the result in the lower elements of dst, and copy the upper 6 packed elements
from a to the upper elements of dst. Each complex number is composed of two adjacent half-precision (16-bit)
floating-point elements, which defines the complex number complex = vec.fp16[0] + i * vec.fp16[1, or the complex
conjugate conjugate = vec.fp16[0] - i * vec.fp16[1].
Rounding is done according to the rounding parameter, which can be one of:
_MM_FROUND_TO_NEAREST_INT|_MM_FROUND_NO_EXC: round to nearest and suppress exceptions_MM_FROUND_TO_NEG_INF|_MM_FROUND_NO_EXC: round down and suppress exceptions_MM_FROUND_TO_POS_INF|_MM_FROUND_NO_EXC: round up and suppress exceptions_MM_FROUND_TO_ZERO|_MM_FROUND_NO_EXC: truncate and suppress exceptions_MM_FROUND_CUR_DIRECTION: useMXCSR.RC- see_MM_SET_ROUNDING_MODE
