RTOS

Abstract

This work presents the basic characteristics and classifications of real time systems and the real time operating systems (RTOS). It also presents the main characteristics of the μC/OS-III RTOS and the ARM architecture with an example of its application in an embedded system based in the ARM (Cortex-M3) architecture. Some of the services given by the RTOS in an embedded system and APIs are used to develop an event detector and generator to test the system. The event generator follows a client-server model between the embedded system and a PC.
