CE 701 Interfacing With Microprocessors

Introduction to Course Importance of course and course objective. The course provides a platform for learning the basics of advanced microprocessors, with its architecture details. The course also introduces low level assembly program. Pre-requisite Basics of digital logic and its design and computer organization.

Course Learning Outcomes 1. understand basic architecture of microprocessors 2. develop logic for programs in assembly language 3. design and develop microprocessor based systems for interfacing peripherals

Syllabus • Microprocessor Architecture: architectural details of 8085, 8086 and 80 x 86 processors, pin functions, read/write machine cycles, memory organization (linear, segmentation, paging), interrupts. • Microprocessor Programming: instruction set of 8086 microprocessor, programming model, modular programming (procedures and macros), BIOS/DOS interrupts and programming of interrupt service routines. • Interfacing: Architecture and interfacing of Intel 8255 Programmable Peripheral Interface, Intel 8259 Programmable Interrupt Controller, Intel 8254 programmable timer, 8237 DMA Controller Analog to Digital Converter and Digital to Analog Converter. • Microcontrollers, interfacing and industrial applications in process control • Self-study: • Microcontrollers, interfacing and industrial applications in process control
