CHAPTER 11 — Immediate Operands and Bitwise Logic

Some machine instructions contain data as part of the instruction. This data is an immediate operand. The ori instruction used in the previous chapter contains an immediate operand.

With a bitwise logic operation two bit patterns are "lined up" and then an operation such as OR or AND is performed between pairs of bits.

Chapter Topics:

• Immediate Operands.
• Bitwise Logic.
• Bitwise OR, AND, and XOR
• Format of Machine Instructions.
• Zero Extension of a Bit Pattern.
• OR Immediate with $0 as a Load Instruction.
