In this tutorial we will learn about different Addressing Modes and Instruction Cycle in Computer Architecture.
Addressing modes are an aspect of the instruction set architecture in most central processing unit (CPU) designs. The various addressing modes that are defined in a given instruction set architecture define how machine language instructions in that
8 Aug 2018 Types of Addressing Modes. Implied Addressing Mode: In this mode the operands are specified implicitly in the definition of an instruction. Immediate Addressing Mode: In this mode the operand is specified in the instruction itself or we can say that, an immediate mode instruction has an operand rather than an address.
Addressing Modes– The term addressing modes refers to the way in which the operand of an instruction is specified. The addressing mode specifies a rule for interpreting or modifying the address field of the instruction before the operand is actually executed.
