VSSUBU.VV

Vector Saturating Integer Subtract Unsigned

VSSUBU.VV vd, vs2, vs1, vm

Subtracts unsigned integers with saturation (clips to 0 instead of wrapping).

Details

Performs element-wise unsigned saturating subtract on two vector registers, writing results to vd. The number of elements processed is determined by vl, and masking is controlled by vm.

Pseudocode Operation

foreach(i < vl): vd[i] = saturate_u(vs1[i] - vs2[i]);

Example

VSSUBU.VV v1, v4, v2, v0.t
