The Processor is the heart of the Embedded System and it can be anything like a Microprocessor, Microcontroller, DSP, CPLD (Complex Programmable Logic Device) or an FPGA (Field Programmable Gated Array).Īll these devices have one thing in common: they are programmable i.e., we can write a program (which is the software part of the Embedded System) to define how the device actually works.Įmbedded Software or Program allow Hardware to monitor external events (Inputs / Sensors) and control external devices (Outputs) accordingly. If we consider a simple Embedded System, the main Hardware Module is the Processor. Programming Embedded SystemsĪs mentioned earlier, Embedded Systems consists of both Hardware and Software.
Some of the embedded systems in a Car are Anti-lock Braking System (ABS), Temperature Monitoring System, Automatic Climate Control, Tire Pressure Monitoring System, Engine Oil Level Monitor, etc.Īlso read EMBEDDED SYSTEMS & ITS REAL TIME APPLICATIONS. A modern day Car has several individual embedded systems that perform their specific tasks with the aim of making a smooth and safe journey. If no new instructions are given for the next wash, then the washing machines repeats the same set of tasks as the previous wash.Įmbedded Systems can not only be stand-alone devices like Washing Machines but also be a part of a much larger system. It takes some inputs from the user like wash cycle, type of clothes, extra soaking and rinsing, spin rpm, etc., performs the necessary actions as per the instructions and finishes washing and drying the clothes. We use washing machines almost daily but wouldn’t get the idea that it is an embedded system consisting of a Processor (and other hardware as well) and software. A good example for an Embedded System, which many households have, is a Washing Machine. Different Components of an Embedded C ProgramĪn Embedded System can be best described as a system which has both the hardware and software and is designed to do a specific task.Basic Structure of an Embedded C Program (Template for Embedded C Program).Introduction to Embedded C Programming Language.Factors for Selecting the Programming Language.
