Purpose:

Vector Floating-Point Division

Vector floating-point division.

Description:

wd[i] = ws[i] / wt[i]

The floating-point elements in vector ws are divided by the floating-point elements in vector wt. The result is written to vector wd.

The divide operation is defined by the IEEE Standard for Floating-Point Arithmetic 754TM-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 754TM2008.

Operation:

FDIV.W
   for i in 0 .. WRLEN/32-1
      WR[wd]32i+31..32i = DivideFP(WR[ws]32i+31..32i, WR[wt]32i+31..32i, 32)
   endfor
FDIV.D
   for i in 0 .. WRLEN/64-1
      WR[wd]64i+63..64i = DivideFP(WR[ws]64i+63..64i, WR[wt]64i+63..64i, 64)
   endfor
function DivideFP(tt, ts, n)
   /* Implementation defined divide operation. */
endfunction DivideFP

Exceptions:

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