Format:

FSQRT.df 

FSQRT.W wd,ws

FSQRT.D wd,ws

Purpose:

Vector Floating-Point Square Root

Vector floating-point square root.

Description:

wd[i] = sqrt(ws[i])

The square roots of floating-point elements in vector ws are written to vector wd.

The square root operation is defined by the IEEE Standard for Floating-Point Arithmetic 754^TM-2008.

The operands and results are values in floating-point data format df.

Restrictions:

Data-dependent exceptions are poss ible as s pecified by the I EEE Standard for Floating-Point Arithmetic 754^TM2008.

Operation:

FSQRT.W
   for i in 0 .. WRLEN/32-1
      f = SquareRootFP(WR[ws]32i+31..32i, 32)
      WR[wd]32i+31..32i = f
   endfor
FSQRT.D
   for i in 0 .. WRLEN/64-1
      f = SquareRootFP(WR[ws]64i+63..64i, 64)
      WR[wd]64i+63..64i = f
   endfor
function SquareRootFP(tt, ts, n)
   /* Implementation defined square root operation. */
endfunction SquareRootFP

Exceptions:

Reserved Instruction Exception, MSA Disabled Exception, MSA Floating Point Exception.
