This lab provides technical information about the microprocessor that will help the students to gain knowledge about 8 bit and 16 bit microprocessors. A lab manual on microprocessor is provided with some programming examples to help students understand the logic of programs. For 8085 microprocessor, kit(VMC-8506) is used for programming. Various I/O chips used in the kit are 8279,8255,8253,8251 and 8259.

For 8086, computer software is there to help students in making and running their programs.Practical demonstration of the programming concepts done in classrooms will enhance the understanding of the students. The experiments included in the curriculum covers all the concepts of programming studied in theory. Some additional value added experiments are also included in the end.

The students are provided with a comprehensive Lab Manual, which is almost self explanatory. All the experiments are well documented clearly so that the students are able to perform the experiments with ease and proper understanding.
