Overview

Introduction of microprocessors & microcontrollers was a turning point in the era of electronic product design.

Ability of programs to have decision making capabilities which is not possible with conventional discrete logic was a major breakthrough in designing intelligent products.

Today 16 bit, 32 bit processors & microcontrollers dominate industrial scene & consumer applications.

8086 processor, 80386 processor, 8051 microcontroller & other programmable peripherals from Intel are the ideal vehicles to make the students understand microprocessor architecture, programming & integrated systems.

Objectives

Understanding microprocessor architecture , assembly language programming, microprocessor based system design, Microcontroller architecture & Embedded system design.

Understanding all concepts in theory by practically trying out programming and experiments.

Developing analytical skills and problem solving abilities of the students.
