A Level Computer Science: Types of Processor

Which of the following is not an aspect of Von Neumann Architecture?

• It makes use of the "Stored Program Concept"

• There is a processing unit that contains an Arithmetic and Logic unit

• Data and instructions are stored separate memories

• Instructions and data are transferred via single shared bus

Which of the following correctly describes the "Von Neumann Bottleneck"?

• The CPU is overclocked and becomes too hot

• There is insufficient memory to store instructions

• The CPU has data to process, but no instructions to carry this out

• The CPU is idle while it waits for data to be sent

Which of the following partially mitigates the impact of Von Neumann bottleneck?

• Through the use of the cache

• By adding more RAM to the computer

• By overclocking the CPU

• The Fetch Execute Cycle

Which of the following statemens are true TRUE? (Select as many as appropriate)

• Harvard Architecture makes use of a singe, shared memory for data and instructions

• Harvard Architecture makes use of different buses to transmit data and instructions

• Harvard Architecture makes use of separate memories for data and instructions

• Harvard Architecture makes use of a single bus to transmit data and instructions

Which of the following statements about Von Neumann and Harvard Architectures are true? Select as many answers as you feel are appropriate

• Harvard architecture is used in embedded systems and digital signal processing

• Von Neumann architecture is more complex and costly to design/implement

• In VN architecture, data and instructions use the same word size

• Harvard architecture makes use of two buses to transfer instructions and data

• In Harvard architecture, data and instructions use the same word size

Which of the following is NOT an advantage of Von Neumann Architecture?

• The design of Control Unit is simplified

• Data from memory/devices can be accessed in the same way

• Only one data bus is needed

• Ideal for embedded systems

TRUE OR FALSE: Modern CPU's often incorporate aspects of both Von Neumann and Harvard Architecture
