vclmulh.vx
Vector carry-less multiply high by scalar
Performs a carry-less multiply operation on each element in vector register vs2 with scalar register xs1, storing the high bits of the result in vector register vd according to mask vm.
| This instruction must have data-independent timing when extension Zkt is enabled. |
Decode Variables
Bits<1> vm = $encoding[25];
Bits<5> vs2 = $encoding[24:20];
Bits<5> xs1 = $encoding[19:15];
Bits<5> vd = $encoding[11:7];
