3.2.4 Shift and R o t a t e Instructions
The arithmetic shift instructions (ASR and ASL) and logical shift instructions
Table 3-4 is a summary of the shift and rotate operations,
and without the extend bit. All shift and rotate operations can be performed
on either registers or memory.
may be specified in the instruction operation word (to shift from 1-8 places)
or in a register (modulo 64 shift count).
sition only. The SWAP instruction exchanges the 16-bit halves of a register.
Performance of shift/rotate instructions is enhanced so that use of the ROR
and ROL instructions with a shift count of eight allows fast byte swapping.
(LSR and LSL) provide shift operations in both directions. The ROR, ROL,
ROXR, and ROXL instructions perform rotate (circular shift) operations, with
Register shift and rotate operations shift all operand sizes. The shift count
Memory shift and rotate operations shift word-length operands one bit po-
