Purpose:

Vector Signed Minimum

Vector and vector signed minimum.

Description:

wd[i] = min(ws[i], wt[i])

Minimum values between signed elements in vector wt and signed elements in vector ws are written to vector wd.

The operands and results are values in integer data format df.

Restrictions:

No data-dependent exceptions are possible.

Operation:

MIN_S.B
   for i in 0 .. WRLEN/8-1
      WR[wd]8i+7..8i = min_s(WR[ws]8i+7..8i, WR[wt]8i+7..8i, 8)
   endfor
MIN_S.H
   for i in 0 .. WRLEN/16-1
      WR[wd]16i+15..16i = min_s(WR[ws]16i+15..16i, WR[wt]16i+15..16i, 16)
   endfor
MIN_S.W
   for i in 0 .. WRLEN/32-1
      WR[wd]32i+31..32i = min_s(WR[ws]32i+31..32i, WR[wt]32i+31..32i, 32)
   endfor
MIN_S.D
   for i in 0 .. WRLEN/64-1
      WR[wd]64i+63..64i = min_s(WR[ws]64i+63..64i, WR[wt]64i+63..64i, 64)
   endfor
function min_s(ts, tt, n)
   t = ttn-1 || tt
   s = tsn-1 || ts
   if t > s then
      return ts
   else
      return tt
