fsqrt.s

Floating-Point Square Root Single-Precision

The fsqrt.s instruction computes the square root of fs1 and writes the result is written to fd.

Assembly format

fsqrt.s fd, fs1, rm

Decode Variables

Bits<5> fs1 = $encoding[19:15];
Bits<3> rm = $encoding[14:12];
Bits<5> fd = $encoding[11:7];

Execution

check_f_ok($encoding);
RoundingMode mode = rm_to_mode(rm, $encoding);
F[fd] = f32_sqrt(F[fs1], mode);
mark_f_state_dirty();
