15. Indirect Mode

The chapter discusses various addressing modes in computer architecture, focusing on their mechanisms and processes for executing instructions. Key modes such as immediate, direct, indirect, and register indirect are explained, illustrating the control stages involved in loading operands. The comparative efficiency of these modes is highlighted, particularly the differences in the number of steps required for data retrieval and instruction execution.
