The document then explains the five addressing modes used in the 8085 microprocessor: immediate, register, direct, indirect, and implicit. each addressing mode specifies how the operand or data is addressed in memory for an instruction.
Instruction Addressing Modes Pdf Computer Hardware Computer Science Organization prof. kamalika datta department of computer science and en ineering national institute of technology, lecture 07 instruction format and addressing modes (refer slide time: 00:27). There are several types of instruction formats, including zero, one, two, and three address instructions. each type of instruction format has its own advantages and disadvantages in terms of code size, execution time, and flexibility. D addressing modes. many instructions require two operands for execution (for example transfer of data bet een two registers). the method of identifying the operands position by the instruction format is known as he addressing mode. when two operands are involved in an instruction, the first operand is assumed to be in a. The document discusses data movement instructions in microprocessor systems, explaining different addressing modes like register, direct, indexed, and immediate addressing that are used to specify the operands and destinations of instructions.

The document discusses data movement instructions in microprocessor systems, explaining different addressing modes like register, direct, indexed, and immediate addressing that are used to specify the operands and destinations of instructions. An operation code field that specifies the operation to be performed. an address field that designates a memory address or a processor registers. a mode field that specifies the way the operand or the effective address is determined. Relative addressing — the instruction specifies an offset of displacement, which is added to the program counter (pc) to get the effective address of the operand. Addressing modes specify how to calculate the effective memory address of an operand by using information held in registers and or constants contained within a machine instruction. Addressing modes of an isa specifies how to calculate the effective address of the operand (s) from the instruction. addressing mode is encoded in the instruction.
