Question

Characteristics of von Neumann architecture?

Answer 1

that uses a central processing unit (CPU) and a single separate storage structure (memory) to hold both instructions and data. Characteristicsof the Von Neumann's architecture: a) memory; b) control unit; c) arithmetic logic unit; d) input / output interface.

Answer 2

Hi there!
Here's the answer:

¶¶¶ Von-neumann Architecture ¶¶¶

- It is alse called as 'Princeton Architecture'.

*** Block diagram of Von-Neumann Architecture is shown in attachment.

• In Von-neumann Architecture, Single Bus is shared for fetching both Data and Instructions.

Eg: ARM7, Pentium

• The cost is low.
[ Requires less wires/ Less Hard wiring Connection ]

• Throughput(Speed) is less.
[ As parallel fetching of Instruction & Data can't be possible
^ Due to single bus, first instructions are fetched, then data are fetched. ]

• Due to Single Memory block for both Instructions & Data:

- There is a chance of Program Memory Corruption

- There may be Memory Alignment Problems

- Self Modifying Codes are available.
