Description

1Microprocessor and Microcontroller by Prof. Saurabh Chaudhury (co-authored with Dr. Risha Mal) is an authoritative academic textbook designed for engineering students. Published in collaboration with institutions like the National Institute of Technology (NIT), Silchar, the book is engineered to bridge foundational computing theory with practical embedded system design.

Book Core Scope & Core Objectives

The textbook delivers a comprehensive, structured approach to understanding the architecture, instruction sets, and external hardware interfaces of classic computing chips.

It provides:

Theoretical Balance: Breaks down internal complex circuitry and logic operations using clear block diagrams.

Programming Skills: Transitions students from structural theory to writing functional assembly language programs.

System Design: Teaches readers how to design custom hardware by connecting CPUs with peripheral memory and timing controllers

The book is methodically split into distinct modules to ease the learning curve:

1. Foundation of Computing & 8-Bit Architecture (Intel 8085)Explores the essential differences between a general-purpose microprocessor (standalone CPU) and a microcontroller (all-in-one chip with integrated RAM/ROM).Introduces the internal layout of the Intel 8085 processor, focusing on register configurations, timing delays, and interrupt signals.

2. Basic Programming Concepts & Assembly LanguageTeaches fundamental logic tracking using standard flow chart symbols.Covers data transfer, 16-bit arithmetic mechanics, logic shifting, looping, and counting/indexing techniques.

3. 16-Bit Processing & Peripheral Interfacing (Intel 8086)Deep dives into the modern architecture of the Intel 8086, highlighting physical address segmentation and memory organization.Explains how to establish communication between the processor and vital support hardware, including:8255 PPI (Programmable Peripheral Interface)8253/8254 (Programmable Interval Timers)8237 DMA (Direct Memory Access Controller)8259 PIC (Programmable Interrupt Controller)

4. 8051 Microcontroller Architecture & Memory DecodingShifts focus entirely to embedded processing through the iconic Intel 8051.Breaks down the Program Status Word (PSW) flag bits, register banks, internal RAM/ROM layout, and input/output (I/O) port pin behaviors.Demonstrates how to decode memory addresses to interface external RAM and ROM memory chips with the core processor.

5. 8051 Assembly Programming & ApplicationsOutlines instruction sets and addressing modes specific to the 8051 family.Guides the reader through creating firmware to manage physical inputs and outputs in real-time embedded environments.
