2 cards from this section. Quick, good the night before a test.
What is immediate addressing?
Think of an instruction where a value is specified directly.
How does direct addressing work?
What happens when we load from a specified memory location?
Which addressing mode retrieves data using a reference address stored in a register?
What does 'indirect' imply?
True or False: In immediate addressing, the value to be loaded is not specified directly in the instruction.
Recall what immediate means in terms of addressing.
Design two instructions: one using direct addressing that loads from location 3 and another using register indirect addressing where Register 2 holds 3.
How do both instructions differ in accessing data?
Write a short program that uses displacement addressing to iterate through an array of integers using a base of 0 and incrementing register 1 for each loop iteration.
How can you control the number of iterations while accessing each array entry?
