Architectures :(

Question 1

von neumann architecture

Answer 1

it has:
- single control unit
- ALU
- registers
- memory units
this architecture has shared memory and busses for both instructions and data.

Question 2

advantages of von neumann architecture

Answer 2

• cheaper to develop as the control unit is much easier to design
• programs can be optimised in size

Question 3

harvad architecture

Answer 3

it has:
- single control unit
- ALU
- registers
- memory units
this architecture has separate memories and busses for data and instructions.

Question 4

advantages of harvard architecture

Answer 4

• quicker execution as data and instructions are fetched in parallel.
• memories can be different in size, which can make more efficient use of space.

Question 5

contemporary processing

Answer 5

• it is a combination between harvard architecture ad von neumann architecture.
• von neumann is used when working with data and instructions in main memory.
• harvard is used to divide the cache into instruction cache and memory cache.
