Embedded Real-Time Systems: Core Concepts (Based on K.V.K.K. Prasad’s Approach)

1. Introduction to Embedded Systems

An embedded system is a microprocessor-based system designed to perform dedicated functions, often as part of a larger system. Unlike general-purpose computers, embedded systems are optimized for reliability, power consumption, and cost.

Round Robin: Tasks take turns executing (simple, but bad for real-time).
Priority-Based Preemptive Scheduling: A higher-priority task can interrupt a lower-priority task. This is the standard for Real-Time Operating Systems (RTOS).
Rate Monotonic Scheduling: Assigns priorities based on task frequency (higher frequency = higher priority).

Introduction

Hardware Architecture: Detailed exploration of hardware platforms, including microcontrollers and microprocessors, with a focus on how they interface with the physical world through sensors and actuators. embedded real time systems kvkk prasad pdf
