Instruction Cycle Assessment

What is the primary function of the fetch cycle in the instruction cycle?

• To execute the instruction

• To retrieve the instruction from memory

• To decode the instruction

• To store the result in memory

During which cycle does the control unit interpret the instruction?

• Fetch cycle

• Decode cycle

• Execute cycle

• Store cycle

In the execute cycle, what is typically performed?

• The instruction is sent to memory

• The arithmetic or logical operation is carried out

• The next instruction is fetched

• The instruction is decoded

Which statement best describes the decode cycle?

• It retrieves data from the CPU registers

• It converts the instruction into control signals

• It stores the instruction in memory

• It performs the necessary calculations

What is the first step in the instruction cycle?

• Decode cycle

• Execute cycle

• Fetch cycle

• Write-back cycle

The fetch cycle concludes when which action occurs?

• The instruction is executed

• The instruction is decoded

• The instruction is loaded into the instruction register

• The results are written back to memory

Which of the following components is primarily involved in the decode cycle?

• Arithmetic Logic Unit (ALU)

• Control Unit

• Memory Unit

• Cache

What is the significance of the execute cycle in the instruction cycle?

• It determines the next instruction to fetch

• It performs operations based on the decoded instruction

• It clears the instruction register

• It checks for input/output operations

How does the fetch cycle affect the overall performance of a CPU?

• It has no impact on performance

• It determines how quickly instructions can be executed

• It only impacts memory storage

• It manages data transfers between devices

What happens to the results after the execute cycle?

• They are discarded

• They are sent back to the memory if necessary

• They are immediately fetched for the next instruction

• They are only stored in the CPU registers
