VCVTPH2PSX
Converts packed half-precision floating-point values to packed single-precision floating-point values with a specified rounding mode.
The following table covers the supported source and destination operands.
| source | destination(s) |
|---|---|
| xmm | xmm |
| m128 | xmm |
| imm | #I |
DO NOT support LOCK
This instruction SHALL be used only in 64-bit mode or 32-bit mode. It is NOT supported in compatibility mode. The instruction requires AVX-512 FP16 extensions to be enabled.
The rounding mode is controlled by the immediate operand, which overrides the rounding control in the MXCSR register. Failure to provide a valid immediate value results in an invalid operation. Precision (#P) and Underflow (#U) exceptions may be triggered based on the conversion result and the active rounding mode.
