14. Handling Different Addressing Modes
The chapter focuses on handling various addressing modes in computer architecture and the corresponding control signals required for instruction execution. It details the operational sequences involved in immediate, direct, and indirect addressing modes, emphasizing the differing microinstructions and control signals for each type. Understanding these modes is crucial for efficient processor instruction handling and control design.
