Experiments

(to be carried out using discrete components)

Note: For the experiments 1 to 6, 8051 assembly programming is to be used.

1 Data transfer – Program for block data movement, sorting, exchanging, finding largest element in an array.
2 Arithmetic instructions: Addition, subtraction, multiplication and division. Square and cube. Operations.
3 Counters
4 Boolean and logical instructions (bit manipulation).
5 Conditional call and return instructions.
6 Code conversion programs – BCD to ASCII, ASCII to BCD, ASCII to decimal, Decimal to
ASCII, Hexa to decimal.7 Programs to generate delay, Programs using serial port and on-chip timer/counters.
Note: Single chip solution for interfacing 8051 is to be with C Programs for the following experiments.
