Components of an Embedded System

An embedded system has three main components : Hardware, Software and time
operating system
i) Hardware

• Power Supply
• Processor
• Memory
• Timers
• Serial communication ports
• Output/Output circuits
• System application specific circuits

ii) Software: The application software is required to perform the series of tasks.
An embedded system has software designed to keep in view of three constraints:
• Availability of System Memory
• Availability of processor speed
• The need to limit power dissipation when running the system continuously in
cycles of wait for events, run , stop and wake up.
iii)  Real Time Operating System: (RTOS) It supervises the application software
and provides a mechanism to let the processor run a process as per scheduling and
do the switching from one process (task) to another process.
