addressing modes Assembly Language Addressing Modes • Memory is accessed by calculating its effective address using the distance (or offset) of the data from the beginning of a segment (usually the data segment) • Memory Addressing modes: Direct Register Indirect Based or Indexed Base-indexed Base-indexed with displacement
Immediate
With immediate addressingmode, the actual data to be used as the operand is included in the instruction itself. Let's say we want to store operand 1 into a register and then add operand 2. With immediate addressing mode, the data values 1 and 2 would be part of the instruction itself as shown below. This would be a relatively fast option since ther...
Direct Addressing
When using direct addressing mode, the address of the operand is specified in the instruction. The processor will retrieve the data directly from the address specified in the instruction. In this figure, the example shows how the instruction tells the processor where to get the data from in memory. The variable addr_of_2is a pointer to the effectiv...
What are the different types of addressing modes?
Let's take a look at the different types of addressing modes, one at a time now. 1. Immediate With immediate addressing mode, the actual data to be used as the operand is included in the instruction itself. Let's say we want to store operand 1 into a register and then add operand 2.
What is direct addressing mode?
Direct Addressing Mode- The address field of the instruction contains the effective address of the operand. Only one reference to memory is required to fetch the operand. It is also called as absolute addressing mode. ADD X will increment the value stored in the accumulator by the value stored at memory location X. 5. Indirect Addressing Mode-
What is register addressing mode?
Register addressing mode indicates the operand data is stored in the register itself, so the instruction contains the address of the register. The data would be retrieved from the register. Here's how this would work: Figure 3. Register Retrieving data from the register is fast and the instructions are shorter because no memory is involved.
What is memory addressing mode?
The addressing mode specifies a rule for interpreting or modifying the address field of the instruction before the operand is actually executed. The 8086 memory addressing modes provide flexible access to memory, allowing you to easily access variables, arrays, records, pointers, and other complex data types.
