4 cards from this section. Quick, good the night before a test.
What is an addressing mode in computer architecture?
Think about how instructions locate their data.
How many steps are needed for immediate addressing mode?
Review the steps we discussed.
What is the number of steps required for immediate addressing mode?
Consider the efficiency of fetching the operand.
True or False: In direct addressing mode, the operand is located at the address specified in the instruction.
Think about how this mode allows access to the operand.
Design a simple assembly instruction set that includes one immediate, one direct, and one indirect instruction. Describe how the control steps differ between them.
Reflect on how each of these instructions accesses their operands differently.
Explain why in modern microprocessors, immediate mode is often preferred for simple operations.
Consider how speed impacts computational efficiency.
