These instructions are executed in the scalar shift unit. They
shift values in an S register by an amount specified by jk. All
shifts are end off with zero fill.
The 052 instruction shifts (Si)
1
eft j k places and enters
the
result
into So.
The 053 instruction shifts (Si)
right by 64-jk places and enters the
result into So.
The 054 instruction shifts (Si)
left jk places and enters
the
result
into Si.
The 055 instruction shifts
(Si)
right by 64-jk places and enters the
result into Si.
