Question

Which of the following statements are true for von Neumann architecture?

(a) shared bus between the program memory and data memory

(b) separate bus between the program memory and data memory

(c) external bus for program memory and data memory

(d) external bus for data memory only

The question was posed to me in a job interview.

My question comes from RISC Processor in section Embedded Processors of Embedded Systems

Answer 1

Right choice is (a) shared bus between the program memory and data memory

Best explanation: von Neumann architecture shares bus between program memory and data memory whereas Harvard architecture have a separate bus for program memory and data memory.
