VFWCVT.F.X.V

Vector Widening Integer to Float Convert

VFWCVT.F.X.V vd, vs2, vm

Converts N-bit integers to 2*N-bit floats (e.g., Int16 -> FP32).

Details

Performs a widening operation, producing results twice as wide as the source elements. Results are written to vd using 2× the element grouping (EEW). The number of elements and masking are governed by vl and vm.

Pseudocode Operation

foreach(i < vl): vd[i] = int_to_wide_float(vs2[i]);

Example

VFWCVT.F.X.V v1, v4, v0.t
