Indexed Addressing
Indexed addressing is a memory addressing mode in computer architecture and assembly language programming where an index register's value is added to a base address to compute the effective address of an operand. It is commonly used for efficient array and data structure access, allowing iteration through elements with simple register increments. This mode simplifies code by enabling loops that process sequential memory locations without hardcoding addresses.
Developers should learn indexed addressing when working with low-level programming, embedded systems, or performance-critical applications to optimize memory access patterns. It is essential for implementing data structures like arrays, strings, and buffers in assembly language or systems programming, as it reduces code size and improves execution speed by leveraging hardware support for address calculation.
