– We may think of languages (C, C++), but computation model is the key • Common computation models: – Sequential program model • Statements, rules for composing statements, semantics for executing them – Communicating process model • Multiple sequential programs running concurrently – State machine model • For control dominated systems, monitors control inputs, sets control outputs – Dataflow model • For data dominated systems, transforms input data streams into output streams – Object-oriented model • For breaking complex software into simpler, well-defined pieces.

Date: 30-12-16 Online course on Embedded Systems MODULE -1 (Introduction) Embedded Systems is simply the brain of the most of the electronics based systems to access, process, store and control the data. Few simple electronics circuits can be intelligently hardware designed without a microprocessor or microcontroller but is not worth the economics except for simple passive operations.

So it's more or less must to put this so called silicon brain, which we engineers call as microcontroller in all electronics systems. Embedded market is experiencing best of it's times and double-digit market growth will continue for some more years.

It will continue to grow as long as semiconductor ICs are used for data processing. This may be vague but to be precise, your career growth is assured for another five years. This is only a prediction/extrapolation based on the current trends in the industry. Honey Singh Lungi Dance Dj Mix Download. Who knows what may come in future, however next two years, it's going to be very hot and growing field.

That too for India, where engineers have extra edge over other regions when it comes to programming will surely lead in the growth. Though programming is a major task in embedded systems.

Programming knowledge alone won't help much in getting into this world. The real challenge is in understanding the electronics hardware and also other interface hardware (Automobile engine, heart patient's ECG, to a motor in a satellite).

Here in this free online course on embedded hardware and software, our objective is to train in embedded systems design to pass entry-level stage and prepare to deep dive into complex embedded systems world, if you find it easy and interesting. We recommend the readers/attendees for this course should be a holder of Bachelor of Engineering/Technology or Bachelor of Sciences in Electronics or it's closely allied branches.

Otherwise if you are strong in theoretical parts of analog circuits, digital circuits, and microprocessor can also grasp this content easily. One thing is must; you should love C programming. What is Embedded System?

Being an electronic engineer, you might have seen PC desktop's motherboard; it's an embedded system. It has microprocessor (Pentium or Athlon), memory (DRAM DIMM module and onboard SRAM), I/O interface (keyboard, mouse etc.), Peripheral communication interface (PCI, USB port, etc). This PC system's architecture is designed for application such as net surfing, excel, word, powerpoint, and you know the rest!!! Say you want to use same computer to monitor the engine of your bike or car. Can you think of using big PC for that purpose?

It's so impractical. The i/p and o/p are totally different, here comes customizing your own microprocessor/microcontroller, memory, display, i/o and peripheral interface and also the operating system. This field of designing application specific computer systems is called embedded systems development. If the response of the computer system need to be real time and highly reliable then it's called Real Time Embedded System. The real time means, say in a control system where a speed of motor need to varied the moment some parameter deflect from it's original value, then it's real time; no waiting or hanging. To define in a sentence, Embedded Systems is a special purpose computer system/board, which encapsulates all the devices such as processor, memory, interface and control in single package or board to perform only a specific application tasks.

Figure 1: Sample block diagram of a typical embedded system. Figure 2: PowerPC based embedded board. The most common examples are, Cell-phones Automatic Teller Machine The Digital Interfaced Gasoline Station Airborne Flight Control System Automotive Engine Health Monitoring System Home Security Systems Modern Air-conditioners Washing Machines Medical Equipment DVD Players Printers Medical Equipment The list goes on. Wherever the microcontroller is used it's embedded computer.

The leading applications of embedded market are, Communication Computer Peripherals Industrial Control and Automotive Consumer Electronics Test and Measurement Medical Military/Aerospace This only is a list of popular applications. The embedded is now getting into lot more interesting applications such as RFID, Agriculture etc. Each application need some domain knowledge of it's interface hardware. Say the project is to develop a coffee vending machine controller; the embedded programmer/designer has to have knowledge on how the valves dispensing hot water and milk operate and their technical specification. The user interface design is different for each application. Some application may not need graphic interface at all but some may need audio interface. Embedded systems - Learning curve Development for embedded systems is different from common practices in many ways.

For new developers in the embedded systems world, there is a learning curve to understand where conventional practices are no longer valid in this new environment. To be an embedded systems developer, s/he need to know many things about the hardware on which software will be executed. Often embedded systems are connected to some sort of control system (activating some switch, rotating a motor) and the developer also needs knowledge of that system as well. If the CPU and/or the operating system are different on the target embedded platform, s/he have to do cross-platform development, which has its own issues. There are different testing techniques as well because most of the embedded systems don't have a monitor screen where error messages or test results can be displayed.

All of these issues make embedded systems development much more complicated than writing a program on a UNIX machine (or a windows PC) and then executing it.
