Lab and Practical works

Laboratory Works:

The laboratory work includes Assembly language programming using 8085/8086/8088 trainer

kit. The programming should include: Arithmetic operation, base conversion, conditional

branching etc. The lab work list may include following concepts:

1. Assembly language program using 8085 microprocessor kit and 8085 microprocessor


2. Use of all types of instructions and addressing modes.

3. Program including basic arithmetical, logical, looping, bitwise and branching.

4. Assembly language programming using 8086 microprocessor emulator, using any types

of Assembler, including the different functions of 21H.
