Microprocessor Lab: Counting Odd/Even Numbers and Sorting Arrays, Exercises of Microprocessors

Anna UniversityMicroprocessors

Two microprocessor lab programs for counting odd and even numbers and sorting arrays in ascending order. The first program uses a loop to count the number of odd and even numbers in a memory location, while the second program sorts an array in ascending order using a repeat-until loop. These programs can be useful for students studying microprocessor programming and digital electronics.
