RTOS (Real-Time Operating System): Powering Embedded Systems

Introduction

In today’s connected world, many devices need to respond instantly to user inputs and environmental changes. This is where an RTOS (Real-Time Operating System) comes into play. Unlike general-purpose operating systems, an RTOS is designed to process data and tasks within strict timing constraints. From automotive systems to medical devices, RTOS (Real-Time Operating System) ensures that operations are executed reliably and on time.

What is RTOS (Real-Time Operating System)?

An RTOS (Real-Time Operating System) is a specialized operating system that manages hardware resources, tasks, and real-time requirements. It ensures tasks are executed within precise time limits, making it essential for applications where delays are unacceptable. Unlike traditional OS, an RTOS focuses on predictability, minimal latency, and deterministic performance.
