Microprocessor Architecture and Interfacing Lab

1. (i) Familiarization with 8085 microprocessor kit, hardware and software commands. (ii) Detailed description of commands: substitute, move, go to and search. 2. To draw a flowchart and write a well-documented assembly language program (ALP) for addition of two 16 bit hexadecimal numbers. Provision should exist for storing result and carry generated after addition. 3. To draw a flow chart and write a well-documented assembly language program (alp) for subtraction of 16 bit hexadecimal numbers and store the result at some memory location. 4. To draw a flowchart and write an alp for the addition of ‘n’ number of data bytes stored in memory locations consecutively. Save carry if any generated during addition. Store the entire sum at two consecutive memory locations. 5. To draw flow chart and write an alp for checking a hex number for odd or even parity, if the parity is odd, store 00 at some given memory location and if the parity is even, store ee at that location. 6. To draw a flow chart and write program for multiplication of two 8-bit numbers by repetitive additions (provision for storing 16-bit result). 7. To draw a flow chart and write program for division of 16-bit number with an 8-bit number. 8. To draw a flow chart and write program to arrange the given ‘n’ numbers stored in a block of memory locations in (i) ascending order (ii) descending order. 9. To write an assembly language program for finding the square of the number by lookup table technique. The values of the number whose squares to be found are given to be between the decimal number 1 to 9. 10. To draw a flow chart and write program to find the largest number of the given numbers stored at consecutive memory locations. Store the largest number at some memory location. 11. To interface relay and opto-isolator with Microprocessor 8085. 12. To interface ADC and DAC with Microprocessor 8085.
