The chapter explores various addressing modes in computer architecture, detailing immediate, direct, indirect, and displacement addressing. It provides concrete examples to clarify how each mode works, particularly in relation to registers and memory locations. The importance of addressing modes in executing instructions and managing loops in programming is also highlighted.
Different addressing modes allow various methods to access data in memory.
Immediate addressing provides data directly within the instruction.
Displacement addressing enables dynamic access patterns for loops and arrays.
A mode where the operand is specified directly within the instruction.
The operand is in a specific memory location directly referenced by the instruction.
The instruction points to a memory location that contains another address where the actual operand is located.
Combines a base address from a register with an offset to find the effective address of the operand.
Uses the program counter (PC) as a base to calculate the address of the operand.
Utilizes a base register that holds a memory address to calculate an effective address using an added displacement.
Uses a general-purpose register as an index, often utilized in accessing elements of an array.
