VFREDMAX.VS

Vector Float Reduction Maximum

VFREDMAX.VS vd, vs2, vs1, vm

Reduces a float vector to a scalar by finding the maximum element.

Details

Performs a vector reduction: applies the operation across all active elements of vs2, using vs1[0] as the initial accumulator, and writes the scalar result to vd[0]. Active elements are determined by vl.

Pseudocode Operation

vd[0] = max(vs1[0], max_element(vs2));

Example

VFREDMAX.VS v1, v4, v2, v0.t
