5 cards from this section. Quick, good the night before a test.
What is the primary function of the control unit in the CPU?
Think about the signals that direct data flow.
Define 'opcode' as it relates to the control unit.
It's part of the instruction that contains operational details.
What is the role of the control unit in the CPU?
Consider which part of the CPU drives its operations.
True or False: Flags in the control unit are only used for arithmetic operations.
Think about the various operations that utilize flags.
Design a control unit for a simplified CPU that handles three instructions: LOAD, ADD, and JUMP. Specify the control signals needed for each operation.
Consider how each instruction impacts the flow of control signals.
Create a timing diagram that represents the execution of an ADD operation in a CPU. Include the steps involved.
Think about how each step aligns with clock cycles and control signals.
