Question

Match the type of memory reference to it's definition Immediate addressing absolute/direct addressing 1. The name (the number) of the CPU register is part of the instruction. 2. The "data" is a constant. 3. A register has the address, and when the instruction is done, that register is incremented or decremented. 4. The Base register points to the start, and then another number is added to get there 5. The memory address is part of the instruction base and displacement addressing register mode auto increment/autodecrement

Answer 1

Immediate addressing - data is constant

absolute / direct addressing mode.-memory address is part of instruction

Base and Displacement addressing- base register points to the start , and then another number is added to get there.

Register mode - the name(the number) of the CPU register is a part of instruction-register mode

Auto increment / Autodecrement - A register has the address, and instruction is done , that register is incremented or decremented-auto incremented or decremented.

Explanation : All the above addressing modes indicates the method where the instruction operation is stated.These modes are employed across several policies.The immediate operand contain constant data.The absolute addressing employs the operand real address and also helpful for accessing just the normal variables.Base register address is attained with the summation of base register and address field.Auto increment / Autodecrement which contains operand address where the increment =following operand addressing and decrement = ahead of oprand addressing
