A DAY IN MICROPROCESSOR LAB.........

  This was our second day in a lab. We had one day theory in microprocessor and toady we tried at applying what we have learned in writing programs. As the previous day we were grouped into 4 and each group had two members. We were to do two programs. The questions chosen by my group is given below.

1. Develop a program to convert decimal number to hexadecimal.

2. Find the square root of a number using successive approximation.

          We were able to execute the programs successfully.

ALGORITHM TO FIND SQUARE ROOT (SUCCESSIVE APPROXIMATION)

1. Set C as 01

2. Set E as 01

3. Set A as 09

4. Subtract A and C

5. Go to step 10 if A=0

6. Increment C by1

7. Increment C by 1

8. Increment E by 1

9. Repeat step 4-8

10. Copy the contents of E to A 

11. Store the value of A to a memory location

12. Stop

ALGORITHM TO CONVERT DECIMAL TO HEXADECIMAL (eg: 255)

1. Set A as 0

2. Set B as 02

3. Set C as 05

4. Set D as 05

5. Set E as 64

6. Go to 10  step if B=A

7. Sum contents of A and E

8. Decrement B by 1

9. Repeat steps 7-8 until B not equal to 0

10. Set the value of E as 0A

11. Go to step 15 if C=A

12. Sum the contents of E and A

13. Decrement C by 1

14. Repeat steps 12-13 until C not equal to 0

15. Sum the contents of D and A

16. Store the contents of A in a memory location

17. Stop
