Course Outcomes:

After studying this course, students will be able to:

1. Construct the combinational circuits, using discrete gates and pro­ grammable logic devices.

2 Describe how arithmetic operations can be performed for each kind of code, and also combinational circuits that implement arithmetic opera­ tions.

3. Design a semiconductor memory for specific chip design.

4. Design embedded systems using small microcontrollers, larger CPUs/DSPs, or hard or soft processor cores.

5. Synthesize different types of I/O controllers that are used in embed­ded system.

Question paper pattern:

• Examination will be conducted for 100 marks with question paper containing 10 full questions, each of 20 marks.
• Each full question can have a maximum of 4 sub questions.
• There will be 2 full questions from each module covering all the topics of the module.
• Students will have to answer 5 full questions, selecting one full question from each module.
• The total marks will be proportionally reduced to 60 marks as SEE marks is 60.
