COMPUTER ARCHITCTURES

Question 1

What is von neumann architecture?

Answer 1

computer architecture in which there is a single shared memory and shared bus for both data and instructions

Question 2

What is harvard architecture?

Answer 2

computer architecture in which there are 2 separate memories and separate buses for data and instructions

Question 3

What is von neumann architecture used in?

Answer 3

• PCs
• servers
• embedded systems with only control functions
• high performance computers

Question 4

What is harvard architecture used in?

Answer 4

• digital signal processing
• embedded systems
• mobile communication systems
• audio, speech and image processing systems
• micro controllers

Question 5

Advs of harvard over von neumann

Answer 5

• faster execution: separate memory for data and instructions allows simultaneous fetching, speeding up processing
• reduced bottlenecks: with separate buses for data and instructions, harvard architecture avoids delays that occur when both share the same bus, leading to faster processing
• faster data transfer: independent paths for instructions and data allow faster, more efficient data transfer to and from the CPU

Question 6

Advs of von neumann over harvard

Answer 6

• simpler and cheaper: von neumann uses a single memory and bus for both instructions and data, making it simpler and cheaper to design and implement
• easier programming: von neumann architecture uses a single memory for both data and instructions, simplifying code management, debugging, and dynamic changes during execution
