Introduction
The world is being captured by the small devices. These small devices are capturing our life at a very rapid rate. You will find your day-to-day devices getting smaller and smaller, yet are capable of outperforming their ancestors in terms of performance, efficiency.
Embedded realtime programming was once looked upon as a niche skill that many programmers can keep themselves away from, but not now anymore. The focus now is on very intelligent devices. Let us consider the good old washing machine. The main purpose of a washing machine is to wash clothes. But the modern world has extended it to include special features and give more control thereby optimizing actual process of washing clothes. Present day washing machines come complete with sensors, which maintain optimum water temperature, cloth dependant spin speed, number of spins, etc. They take care of filling water, heating it to a particular temperature, mixing the optimum amount of detergent, soaking the clothes in water for just the right time, the soft tumble for extracting dirt, aggressive tumble for removing stains, and finally the spin-dry. More necessarily, this happens with the minimum amount of user intervention. The user just has to select type of clothes being put inside the machine. (and obviously how dirty they are!☺ ) All this is not magic. This is because somebody hit upon a brilliant idea that we can use a small microprocessor to automate a lot of the dreary process of washing.
