An embedded system is nearly any computing system other than a desktop computer. An embedded system is a dedicated system which performs the desired function upon power up, repeatedly.

Embedded systems are found in a variety of common electronic devices such as consumer electronics ex. Cell phones, pagers, digital cameras, VCD players, portable Video games, calculators, etc., Embedded systems Notes pdf free Download.Embedded-systems-notes-material-pdf-download

Embedded systems are found in a variety of common electronic devices, such as:

(a)consumer electronics — cell phones, pagers, digital cameras, camcorders, video cassette recorders, portable video games, calculators, and personal digital assistants;

(b) Home appliances microwave ovens, answering machines, thermostat, home security, washing machines, and lighting systems;

(c) Office automation fax machines, copiers, printers, and scanners;

(d) Business equipment cash registers, curbside check-in, alarm systems, card readers, product scanners, and automated teller machines;

(e) Automobiles — transmission control, cruise control, fuel injection, anti-lock brakes, and active suspension

Classifications of Embedded systems

Small-Scale Embedded Systems:

These systems are designed with a single 8- or 16-bit microcontroller; they have little hardware and software complexities and involve boardlevel design. They may even be battery operated. When developing embedded software for these, an editor, assembler and cross assembler, specific to the microcontroller or processor used, are the main programming tools. Usually, ‗C‘ is used for developing these systems. ‗C‘ program compilation is done into the assembly, and executable codes are then appropriately located in the system memory. The software has to fit within the memory available and keep in view the need to limit power dissipation when system is running continuously. Embedded systems material pdf download.

Medium Scale Embedded Systems:

These systems are usually designed with a single or few 16- or 32-bit microcontrollers or DSPs or Reduced Instruction Set Computers (RISCs). These have both hardware and software complexities. For complex software design, there are the following programming tools: RTOS, Source code engineering tool, Simulator, Debugger and Integrated Development Environment (IDE). Software tools also provide the solutions to the hardware complexities. An assembler is of little use as a programming tool. These systems may also employ the readily available ASSPs and IPs (explained later) for the various functions—for example, for the bus interfacing, encrypting, deciphering, discrete cosine transformation and inverse transformation, TCP/IP protocol stacking and network connecting functions.

Sophisticated Embedded Systems:

Sophisticated embedded systems have enormous hardware and software complexities and may need scalable processors or configurable processors and programmable logic arrays. They are used for cutting edge applications that need hardware and software co-design and integration in the final system; however, they are constrained by the processing speeds available in their hardware units. Certain software functions such as encryption and deciphering algorithms, discrete cosine transformation and inverse transformation algorithms, TCP/IP protocol stacking and network driver functions are implemented in the hardware to obtain additional speeds by saving time. Some of the functions of the hardware resources in the system are also implemented by the software. Development tools for these systems may not be readily available at a reasonable cost or may not be available at all. In some cases, a compiler or retarget able compiler might have to be developed for these. Embedded Systems Notes and Materials Free Download.
