SLLI.H wd,ws,m

SLLI.W wd,ws,m

SLLI.D wd,ws,m

Purpose:

Immediate Shift Left

Immediate bit count shift left.

Description:

wd[i] = ws[i] << m

The elements in vector ws are shifted left by m bits. The result is written to vector wd.

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

Restrictions:

No data-dependent exceptions are possible.

Operation:

SLLI.B
   t = m
   for i in 0 .. WRLEN/8-1
      WR[wd]8i+7..8i = WR[ws]8i+8-t-1..8i || 0t
   endfor
SLLI.H
   t = m
   for i in 0 .. WRLEN/16-1
      WR[wd]16i+15..16i = WR[ws]16i+16-t-1..16i || 0t
   endfor
SLLI.W
   t = m
   for i in 0 .. WRLEN/32-1
      WR[wd]32i+31..32i = WR[ws]32i+32-t-1..32i || 0t
   endfor
SLLI.D
   t = m
   for i in 0 .. WRLEN/64-1
      WR[wd]64i+63..64i = WR[ws]64i+64-t-1..64i || 0t
   endfor
