Processors CISC RISC

Which of the following is FALSE about von Neumann architecture?

• Data and programs share the same memory.

• The programming instructions and data share the same bus.

• There is no possibility of data being overwritten by instruction and vice versa.

• None of the above.

Why is the speed of a Harvard processor better than that of a von Neumann processor?

• More memory is allocated

• Because program memory is read-only

• Separate buses for program and data enables us to process them simultaneously.

• All of the above
