min

Minimum

Returns the smaller of two signed integers.

Assembly format

min xd, xs1, xs2

Decode Variables

Bits<5> xs2 = $encoding[24:20];
Bits<5> xs1 = $encoding[19:15];
Bits<5> xd = $encoding[11:7];

  raise(ExceptionCode::IllegalInstruction, mode(), $encoding);
}
X[xd] = ($signed(X[xs1]) < $signed(X[xs2])) ? X[xs1] : X[xs2];
