Chapter 2: Architecture of the ARM Processor

What are the functional units in an ARM core connected by?

• The functional units in an ARM core are connected by a bus or interconnect.

• The functional units in an ARM core are connected by wires.

• The functional units in an ARM core are connected by a network.

• The functional units in an ARM core are connected by a pipeline.

How does data enter the processor core?

• Through the data bus

• Through the power supply

• Through the cooling system

• Through the external storage

Which architecture uses the same bus for data items and instructions?

• Harvard architecture

• Von Neuman

What is the role of the instruction decoder in the ARM architecture?

• To decode instructions into signals for execution

• To store data temporarily

• To manage power consumption

• To handle input/output operations

What is the main difference between Von Neumann and Harvard architectures as shown in the diagram?

• Von Neumann architecture uses a single memory for both instructions and data, while Harvard architecture uses separate memories for instructions and data.

• Von Neumann architecture uses separate memories for instructions and data, while Harvard architecture uses a single memory for both.

• Von Neumann architecture is used in modern computers, while Harvard architecture is obsolete.

• Von Neumann architecture is faster than Harvard architecture.

In the Von Neumann architecture, what type of bus is used?

• Shared bus

• Separate bus

What type of architecture does the ARM processor use?

• Load-store architecture

• Harvard architecture

• Von Neumann architecture

• CISC architecture

What are the two instruction types used by the ARM processor for transferring data?

• A) Load and Store
