Learning Objectives

  • Instructions can be categorized into data transfer, arithmetic, logical, and control types.

  • The execution of control instructions often depends on the state of flags set during operations.

  • Different instruction formats (one-address, two-address, three-address, zero-address) provide various ways to specify operands for operations.

Key Concepts

Data Transfer Instructions

Operations that move data between registers and memory locations.

Arithmetic Instructions

Operations that perform mathematical calculations like addition, subtraction, multiplication, etc.

Control Instructions

Instructions that alter the flow of execution based on certain conditions.

Flags

Binary indicators set by the processor to reflect the outcome of arithmetic or logical operations.

Instruction Formats

The structure of instructions, which may vary (e.g., one-address, two-address) based on the number of operands.
