Fetch to Code Execute Cycle

What are the three stages of the fetch to code execute cycle?

• Input, Process, Output
• Fetch, Decode, Execute
• Read, Write, Store
• Load, Store, Execute

What is the function of the program counter?

• Stores the program instructions
• Carries out the instructions
• Holds the address of the next instruction to be executed
• Stores the data being processed

Where is the program stored in a computer?

• Memory
• Processor
• Control unit
• Input device

What is the role of the central processing unit (CPU)?

• Stores the program instructions
• Processes the data
• Delivers the output
• Stores the data being processed

What happens during the fetch stage of the fetch to code execute cycle?

• The program counter is checked
• The data is processed
• The output is delivered
• The program instructions are stored

What is the purpose of the memory address register?

• Stores the program instructions
• Holds the address of the next instruction to be executed
• Stores the data being processed
• Copies the address from the program counter

What is the function of the control bus?

• Reads the data from memory
• Sends signals to the control unit
• Transfers data between the CPU and memory
• Executes the instructions

What is the purpose of the memory data register?

• Stores the program instructions
• Holds the address of the next instruction to be executed
• Stores the data being processed
• Receives the data from memory

What is the role of the current instruction register?

• Stores the program instructions
• Holds the address of the next instruction to be executed
• Stores the data being processed
• Holds the fetched instruction

What happens during the decode stage of the fetch to code execute cycle?

• The program counter is checked
• The data is processed
• The output is delivered
• The instruction is analyzed
