1.0 INTRODUCTION

1.1 RTOS Features

RTOS suppose to respond inputs immediately without any delay such as an aircraft system. However a real time computing is not a RTOS as its equivalent to fast computing. A real time system operating under static environment and real time programming are not considered a RTOS. The following diagram shows the basic features of a RTOS regardless of its categories like Hard RTOS and Soft RTOS.

2.0 EMBEDDED RTOS MARKET PROJECTIONS 2016 – 2021 2.1 Embedded RTOS Market Revenue

Global combined RTOS embedded system sales revenue will grow 5.9% CAGR during the forecasted period of 2016 – 2021. Combined embedded RTOS market includes embedded hardware, embedded software and 16 -32bit MCUs. Embedded RTOS market is equivalent to 27% of total embedded system market and less than 1% of global IoT market revenue. The market share reveals the potential that is highly likely to grow by 2025. The combined RTOS embedded market will reach US $37.9 billion by 2021.
