CPU Architecture - DG

What register is connected directly to the data bus?

• Memory Address Register

• Memory Data Register

• Program Counter

• Current Instruction Register

To get data from RAM, memory addresses are sent from the CPU down the...

• bus.

• registers.

• ROM.

• cache.

The Control Unit

• Controls the flow of data around the CPU and also decodes instructions

• Only controls the flow of data around the CPU

• Only decodes instructions

• Controls how much power is directed to all components within the computer

The ALU....

• does any maths or logic problems for the CPU

• stores data inside the CPU

• sends out control signals for the CPU

• holds specific data for the fetch-decode-execute cycle

The part of the CPU that directs the operations of the processor

• Control unit

• ALU

• Registers

• Clock

Which of these is NOT a stage of the FDE cycle?

• Fetch

• Execute

• Decide

• Decode

What is the part of the CPU called that performs calculations?

• ALU

• Control Unit

• Program Counter

• Memory

Inside the CPU, you will find:

• ALU, CU, registers, cache memory

• ADU, PC, storage, RAM memory

• ARM, PC, controller, cache memory

• APM, CU, time signal, RAM memory

Which component of the CPU executes instructions based on the decoded instruction obtained during the Fetch-Decode-Execute cycle?

• ALU (Arithmetic Logic Unit)

• Control Unit (CU)

• Registers

• Cache Memory

A type of primary memory that does not need to be refreshed to retain its contents AND whose contents cannot be changed

• RAM

• BIOS

• Flash

• ROM
