CS-601 – Micro Processor and Interfacing

RATIONALE:

The purpose of this subject is to cover the underlying concepts and techniques used in Micro

Processor and Interfacing. In this subject we cover the unique issues associated with designing,

testing, integrating, and implementing microcontroller/microprocessor-based embedded

systems.

List of Experiments

1. Add a data byte located at offset 0500H in 2000H segment to another data byte available at

06000H in same segment and store the resulting 0700H in same segment?

2. Add the contents of memory location 2000H, offset 0500H to the contained of accumulator.

3. Write a program to find the average to two temperature name HI-TEMP and LO-TEMP and

puts the result in the memory location AV-TEMP.

4. Find out the largest number from an unordered array of sixteen 8-bit numbers stored

sequentially in the memory locations starting at offset 0500H in the segment 2000H

5. Move a byte string, 16 bytes long, from the offset 0200H to 0300H in the segment 7000H.

6. Write a program to add a profit factor to each element in a cost array and puts the result in a

PRICES array, where profit factor is 15H and COST =20H, 28H, 15H, 26H, 19H, 27H, 16H,

29H.

7. Write a program to find out the number of positive numbers and negative numbers from a

given series of signed numbers.

8. Write a program that performs the addition, subtraction, multiplications, division of the given

operands. Perform BCD operation for addition and subtraction.

9. A Program to find out the number of even and odd numbers from a given series of 16 bit

hexad4ecimal numbers.
