1. How many types of architectures are available, for designing a device that is able to work on its own?
a) 3
b) 2
c) 1
d) 4
Explanation: There are basically two main types of architectures present, they are Von Neumann and Harvard architectures.
2. Which architecture is followed by general purpose microprocessors?
a) Harvard architecture
b) Von Neumann architecture
c) None of the mentioned
d) All of the mentioned
Explanation: General purpose microprocessors make use of Von Neumann architecture as here a simpler design is offered.
3. Which architecture involves both the volatile and the non volatile memory?
a) Harvard architecture
b) Von Neumann architecture
c) None of the mentioned
d) All of the mentioned
Explanation: In Harvard architecture, both the volatile and the non volatile memories are involved. This is done to increase its efficiency as both the memories are being used over here.
4. Which architecture provides separate buses for program and data memory?
a) Harvard architecture
b) Von Neumann architecture
c) None of the mentioned
d) All of the mentioned
Explanation: Harvard Architecture provides separated buses for data and program memory to fetch program and data simultaneously. By doing this access time is reduced and hence performance is increased.
5. Which microcontroller doesn’t match with its architecture below?
a) Microchip PIC- Harvard
b) MSP430- Harvard
c) ARM7- Von Neumann
d) ARM9- Harvard
Explanation: MSP430 supports Von Neumann architecture.
6. Harvard architecture has _____________
a) dedicated buses for data and program memory
b) pipeline technique
c) complex architecture
d) all of the mentioned
Explanation: Harvard Architecture has dedicated buses for data and program memory and pipeline technique because of this architecture is complex.
7. Which out of the following supports Harvard architecture?
a) ARM7
b) Pentium
c) SHARC
d) All of the mentioned
Explanation: SHARC supports harvard architecture for signal processing in DSP.
8. Why most of the DSPs use Harvard architecture?
a) they provide greater bandwidth
b) they provide more predictable bandwidth
c) they provide greater bandwidth & also more predictable bandwidth
d) none of the mentioned
Explanation: Most of the DSPs use harvard architecture because they provide a wider predictable bandwidth.
9. Which of the following supports CISC as well as Harvard architecture?
a) ARM7
b) ARM9
c) SHARC
d) None of the mentioned
Explanation: SHARC supports both the CISC and the Harvard architecture.
10. Which of the two architecture saves memory?
a) Harvard
b) Von Neumann
c) Harvard & Von Neumann
d) None of the mentioned
Explanation: As only one memory is present in the Von Neumann architecture so it saves a lot of memory.
