Embedded System MCQ [Free PDF] – Objective Question Answer for Embedded System Quiz

61. Which of the following is a traditional method for emulating the processor?

a) CPU simulator
b) SDS
c) ICE
d) Low-level language simulator

Answer: c

The SDS is one of the simulation tools used in embedded systems. CPU simulator and the low-level simulator are the other kinds of simulators used in the embedded system design.

 

62. Which of the following unit protects the memory?

a) memory management unit
b) peripheral unit
c) execution unit
d) bus interface unit

Answer: a

The resources have to be protected in an embedded system and the most important resource to be protected is the memory which is protected by the memory management unit through different programming.

 

63. Identify the standard software components that can be reused in an embedded system design?

a) memory
b) application software
c) application manager
d) operating system

Answer: d

There are certain software components that can be reused in an embedded system design. These are the operating systems, real-time databases, and some other forms of middleware.

 

64. What does ICE stand for?

a) in-circuit EPOM
b) in-code emulation
c) in-circuit emulation
d) in-code EPROM

Answer: c

The ICE or in-circuit emulation is one of the traditional methods used to emulate the processor in the embedded system so that the software can be downloaded and can be debugged in situ in the end application.

 

65. Who proposed the first power model?

a) Tiwari
b) Russell and Jacome
c) Russell
d) Jacome

Answer: a

Tiwari proposed the first power model in the year 1974. The model includes the so-called bases and the inter-instruction instructions. Base costs of the instruction correspond to the energy consumed per instruction execution when an infinite sequence of that instruction is executed. Inter instruction costs model the additional energy consumed by the processor if instructions change.

 

66. Which of the following offers external chips for memory and peripheral interface circuits?

a) Embedded system
b) Peripheral system
c) Microcontroller
d) Microprocessor

Answer: d

Microcontrollers are the CPUs that have integrated memory and peripherals whereas microprocessor offers external chips for memory.

 

68. What kind of socket does an external EPROM to plugged in for prototyping?

a) Piggyback reset socket
b) Multi-socket
c) Piggyback
d) Single socket

Answer: c

Some controllers use a special package called a piggyback socket on the top of the package to allow the EPROM for prototyping.

 

69. Which is the single device capable of providing prototyping support for a range of microcontrollers?

a) Umbrella device
b) OTP
c) RAM
d) ROM

Answer: a

The umbrella device is capable of providing prototyping support for a range of microcontrollers.

 

70. By which instruction does the switching of registers take place?

a) Register instruction
b) EXX instruction
c) Instruction opcodes
d) AXX instruction

Answer: c

Only one set of registers can be used at one time and the switching of registers and data transfer is performed by the EXX instruction.
