VCVTNEPS2BF16
Converts packed single-precision floating-point values to packed bfloat16 floating-point values. The conversion is performed using a rounding mode specified by the immediate operand or the MXCSR register.
The table after the description covers what the source and destinations can be.
| source | destination(s) |
|---|---|
| xmm | xmm |
| m128 | xmm |
DO NOT support LOCK
This instruction is available only in 64-bit mode. It requires the AVX-512 BF16 extension.
The rounding mode is controlled by the immediate byte; if the immediate is not specified, the rounding control field in the MXCSR register SHALL be used. Failure to ensure the correct rounding mode may result in unexpected precision loss. Precision (#P) may be signaled if the result of the conversion is inexact.
