CHAPTER 12 — Shift Instructions and Logic Instructions

It often happens that a bit pattern must be moved left or right within a register. The instructions that do this are the shift instructions.

Chapter Topics:

• Logical shift instructions (sll and srl).
• No-op as a shift instruction.
• Bitwise logic instructions (or, and, xor, nor).
• NOT as a NOR operation.
• MOVE as an OR operation.
• Example program: instruction assembly.
