PRACTICAL COMPONENT OF IPCC (May cover all / major modules)

Experiments

Module – 1

1. Using Keil software, observe the various Registers, Dump, CPSR, with a simple Assembly

Language Programs (ALP).

Module – 2

2. Develop and simulate ARM ALP for Data Transfer, Arithmetic and Logical operations

(Demonstrate with the help of a suitable program).

3. Develop an ALP to multiply two 16-bit binary numbers.

4. Develop an ALP to find the sum of first 10 integer numbers.

5. Develop an ALP to find the largest/smallest number in an array of 32 numbers.

6. Develop an ALP to count the number of ones and zeros in two consecutive memory locations.

Module – 3

7. Simulate a program in C for ARM microcontroller using KEIL to sort the numbers in

ascending/descending order using bubble sort.

8. Simulate a program in C for ARM microcontroller to find factorial of a number.

9. Simulate a program in C for ARM microcontroller to demonstrate case conversion of characters

from upper to lowercase and lower to uppercase.

Module – 4 and 5

10. Demonstrate enabling and disabling of Interrupts in ARM.

11. Demonstrate the handling of divide by zero, Invalid Operation and Overflow exceptions in ARM.
