Sample EE6602 Important questions:

1. Define a System.

A way of doing one or more tasks according to a program.

2. What is an embedded system?
An embedded system employs a combination of hardware & software (a “computational engine”) to perform a specific function; is part of a larger system that may not be a “computer”; works in a reactive and time-constrained environment

3. What are the typical characteristics of an embedded system?

Typical characteristics:
Perform a single or tightly knit set of functions;
Increasingly high-performance & real-time constrained;
Power, cost and reliability are often important attributes
That influence design; Application specific processor design can be a significant component of some embedded systems.
Other characteristics:
• Application specific
• Digital signal processing in ECS
• Reactive
• Real-time
• Distributed

4. What are the advantages of embedded system?

Customization yields lower area, power, cost, etc.,

5. What are the disadvantages of embedded system?

Higher HW/software development overhead design, compilers, debuggers, etc., may result in delayed time to market!

6. What are the applications of an embedded system?

Embedded Systems: Applications:
• Consumer electronics, e.g., cameras, camcorders, etc.,
• Consumer products, e.g., washers, microwave ovens, etc.,
• Automobiles (anti-lock braking, engine control, etc.,)
• Industrial process controllers & avionics/defense applications
• Computer/Communication products, e.g., printers, FAX machines, etc.,
• Emerging multimedia applications & consumer electronics

7. What are the various embedded system designs Modeling

Refining (or “partitioning”)
HW-SW partitioning

8. What are the complicating factors in embedded design?

Complicating factors in the design of embedded systems
• Many of the subtasks in design are intertwined.
• Allocation depends on the partitioning, and scheduling presumes a certain allocation.
• Predicting the time for implementing the modules in hardware or software is not very easy, particularly for tasks that have not been performed before.
