MICROPROCESSOR INTERFACING LABORATORY

Group A

1. Write 8086 Assembly language program (ALP) to add array of N hexadecimal numbers stored in the memory. Accept input from the user.

2. Write 8086 ALP to perform non-overlapped and overlapped block transfer (with and without string specific instructions). Block containing data can be defined in the data segment.

3. Write 8086 ALP to convert 4-digit Hex number into its equivalent BCD number and 5-digit BCD number into its equivalent HEX number. Make your program user friendly to accept the choice from user for: (a) HEX to BCD b) BCD to HEX (c) EXIT. Display proper strings to prompt the user while accepting the input and displaying the result.

4. Write 8086 ALP for the following operations on the string entered by the user. a) Calculate Length of the string b) Reverse the string c) Check whether the string is palindrome OR Make your program user friendly by providing MENU like: (a) Enter the string b) Calculate length of string c) Reverse string d) Check palindrome e) Exit Display appropriate messages to prompt the user while accepting the input and displaying the result.

5. Write 8086 ALP to perform string manipulation. The strings to be accepted from the user is to be stored in data segment of program_l and write FAR PROCEDURES in code segment program_2 for following operations on the string: (a) Concatenation of two strings (b) Number of occurrences of a sub-string in the given string Use PUBLIC and EXTERN directive. Create .OBJ files of both the modules and link them to create an EXE file.

6. Write 8086 ALP to perform multiplication of two 8-bit hexadecimal numbers. Use successive addition and add and shift method. Accept input from the user.

7. Write 8087ALP to obtain: i) Mean ii) Variance iii) Standard Deviation For a given set of data elements defined in data segment. Also display result.
