In the last twenty five years or so, microprocessors and microelectronics in general have brought about a revolution in computer science, telecommunications as well as in space and high-energy physics .This course is intended as a first level course for microcomputer and embedded system design. Designer of an embedded system must have a thorough understanding of hardware, software and system integration. In view of this, various aspects of hardware design, such as interfacing of memory and different types of I/O devices, will be covered in details. As it is customary to write software in machine or assembly language for embedded system applications, laboratory assignments will be on assembly language programming of 8085 and 8051. The students will also learn to use development aids, such as a simulator and an in-circuit-emulator to perform software development, hardware development and hardware-software integration. Finally, each batch of students will implement a complete microcontroller-based system as part of the lab assignment.

Objective:

The significance of the Microprocessors and Microcontrollers Lab is renowned in the various fields of engineering applications. For an Engineer, it is obligatory to have the practical ideas about the applications of Microprocessors and Microcontrollers. By this perspective we have introduced a Laboratory manual cum Observation for Microprocessors and Microcontrollers Lab.

In this laboratory students has to perform the experiments of microprocessor & microcontroller based programming for the first time. The features and facilities available in this laboratory helps the students to do their projects and enhance their knowledge on the latest trends and technologies.
