List of Experiments

Some experiments you can perform after completion of this course:

  • Study of Multiplexer and Demultiplexer.
  • Study of Half Adder and Subtractor.
  • Study of Full Adder and Subtractor.

Some Programs List

Here are some program list to practice:

  • Write a program to add two 8 bit numbers and store the result at memory location 2000.
  • Write a program to multiply two 8 bit numbers stored at memory location 2000 and 2001 and stores the result at memory location 2000 and 2001.
  • Write a program to add two 16-bit numbers. Store the result at memory address starting from 2000.
  • Write a program which tests if any bit is '0' in a data byte specified at an address 2000. If it is so, 00 would be stored at address 2001 and if not so then FF should be storedat the same address.
  • Assume that 3 bytes of data are stored at consecutive memory addresses of the data memory starting at 2000. Write a program which loads register C with (2000), i.e. with data contained at memory address2000, D with (2001), E with (2002) and A with (2001).
  • Sixteen bytes of data are specified at consecutive data-memory locations starting at 2000. Write a program which increments the value of all sixteen bytes by 01.
  • Write a program to add t 10 bytes stored at memory location starting from 3000. Store the result at memory location 300A.
