1.1.1 Structure and function of the processor

What is the purpose of an Accumulator (ACC) in a CPU?

• To store the current instruction being executed

• To carry the memory location address

• To perform arithmetic calculations

• To temporarily store the results of operations

What does the Address Bus do?

• Stores data to be read from or written to memory

• Connects several components of a computer

• Carries the memory location address

• Carries control signals

What is the main function of the Arithmetic and Logic Unit (ALU)?

• To perform arithmetic calculations and logical operations

• To synchronize access and use of data

• To store instructions and data accessed regularly

• To control and manage the execution of instructions

What are Buses in a computer system?

• A small and fast memory in the CPU

• A set of parallel wires connecting components

• A part of the CPU that controls execution of instructions

• A special register to store operation results

What is Cache memory used for?

• To store the memory address of the next instruction

• To temporarily store data to be read from or written to memory

• To carry the memory location address

• To store instructions and data accessed regularly

What does Clock Speed in a CPU determine?

• The capacity of the cache memory

• The number of cores in a processor

• The size of the data bus

• How often instructions are executed

What is Contemporary Processor Architecture known for?

• Combining elements of both Von Neumann and Harvard architectures

• Storing data and instructions in separate memories

• The frequency at which the internal clock generates signals

• The process of fetching, decoding, and executing instructions

What is the role of the Control Bus?

• To carry control signals

• To temporarily store the results of operations

• To carry the memory location address

• To connect and carry groups of bits between components

What does the Control Unit do?

• Controls and manages the execution of instructions

• Carries the memory location address

• Performs arithmetic calculations

• Stores the memory address of the next instruction

What is stored in the Current Instruction Register (CIR)?

• The memory address of the next instruction

• Data to be read from or written to memory

• The current instruction being executed and decoded

• Control signals for execution coordination
